Safety and environmental notices xxv

Acclimation
Server and storage equipment (racks and frames) must be gradually acclimated to the surrounding environment to prevent condensation. When server and storage equipment (racks and frames) is shipped in a climate where the outside temperature is below the dew point of the destination (indoor location), there's a possibility that water condensation can form on the cooler inside and outside surfaces of the equipment when the equipment is brought indoors. Sufficient time must be allowed for the shipped equipment to gradually reach thermal equilibrium with the indoor environment before you remove the shipping bag and energize the equipment. Follow these guidelines to properly acclimate your equipment: · Leave the system in the shipping bag. If the installation or staging environment allows it, leave the
product in the full package to minimize condensation on or within the equipment. · Allow the packaged product to acclimate for 24 hours.1 if there are visible signs of condensation (either
external or internal to the product) after 24 hours, acclimate the system without the shipping bag for an extra 12 - 24 hours or until no visible condensation remains. · Acclimate the product away from perforated tiles or other direct sources of forced air convection to minimize excessive condensation on or within the equipment. 1 Unless otherwise stated by product-specific installation instructions. Note: Condensation is a normal occurrence, especially when you ship equipment in cold-weather climates. All Dell products are tested and verified to withstand condensation that is produced under these circumstances. When sufficient time is provided to allow the hardware to gradually acclimate to the indoor environment, there should be no issues with long-term reliability of the product.
Performing the safety inspection procedure
Before you service the unit, complete the following safety inspection procedure. 1. Stop all activities between the host and the library's tape drives. 2. Turn off the power to the library by pushing in the Power button on the front of the tape library for 4
seconds. 3. Unplug the library's power cord from the electrical outlet and the library's power supply unit. 4. Check the library's power cords for damage, such as a pinched, cut, or frayed cord. 5. If drives are FC/SAS attached, check the tape drive's FC/SAS cable for damage. 6. Check the top and bottom covers of the library for sharp edges, damage, or alterations that expose its
internal parts. 7. Check the top and bottom covers of the library for proper fit. They must be in place and secure. 8. Check the product label at the rear of the library to make sure that it matches the voltage at your
outlet.

the bottom of the rack cabinet. Always install servers and optional devices starting from the bottom of the rack cabinet. · Rack-mounted devices are not to be used as shelves or work spaces. Do not place objects on top of rack-mounted devices. In addition, do not lean on rack mounted devices and do not use them to stabilize your body position (for example, when working from a ladder).
· Each rack cabinet might have more than one power cord. ­ For AC powered racks, be sure to disconnect all power cords in the rack cabinet when directed to disconnect power during servicing. ­ For racks with a DC power distribution panel (PDP), turn off the circuit breaker that controls the power to the system unit(s), or disconnect the customer's DC power source, when directed to disconnect power during servicing.
· Connect all devices installed in a rack cabinet to power devices installed in the same rack cabinet. Do not plug a power cord from a device installed in one rack cabinet into a power device installed in a different rack cabinet.
· An electrical outlet that is not correctly wired could place hazardous voltage on the metal parts of the system or the devices that attach to the system. It is the responsibility of the customer to ensure that the outlet is correctly wired and grounded to prevent an electrical shock. (R001 part 1 of 2)
Caution
· Do not install a unit in a rack where the internal rack ambient temperatures might exceed the manufacturer's recommended ambient temperature for all your rack-mounted devices.
· Do not install a unit in a rack where the air flow is compromised. Ensure that air flow is not blocked or reduced on any side, front, or back of a unit that is used for air flow through the unit.
· Consideration must be given to the connection of the equipment to the supply circuit so that overloading of the circuits does not compromise the supply wiring or overcurrent protection. To provide the correct power connection to a rack, refer to the rating labels on the equipment in the rack to determine the total power requirement of the supply circuit.
· (For sliding drawers) Do not pull out or install any drawer or feature if the rack stabilizer brackets are not attached to the rack. Do not pull out more than one drawer at a time. The rack might become unstable if you pull out more than one drawer at a time.
Safety and environmental notices xxvii

· (For fixed drawers) This drawer is a fixed drawer and must not be moved for servicing unless specified by the manufacturer. Attempting to move the drawer partially or out of the rack might cause the rack to become unstable or cause the drawer to fall out of the rack. (R001 part 2 of 2)
Caution
Removing components from the upper positions in the rack cabinet improves rack stability during relocation. Follow these general guidelines whenever you relocate a populated rack cabinet within a room or building: · Reduce the weight of the rack cabinet by removing equipment, starting at the top of the rack cabinet.
When possible, restore the rack cabinet to the configuration of the rack cabinet as you received it. If this configuration is not known, you must do the following: ­ Remove all devices in the 32U position (compliance ID RACK-001) or 22U (compliance ID RR001)
and above. ­ Ensure that the heaviest devices are installed in the bottom of the rack cabinet. ­ Ensure that there are little-to-no empty U-levels between devices installed in the rack-cabinet below
the 32U (compliance ID RACK-001) or 22U (compliance ID RR001) level, unless the received configuration specifically allowed it. · If the rack cabinet you are relocating is part of a suite of rack cabinets, detach the rack cabinet from the suite. · If the rack cabinet you are relocating was supplied with removable outriggers, they must be reinstalled before the cabinet is relocated. · Inspect the route that you plan to take to eliminate potential hazards. · Verify that the route that you choose can support the weight of the loaded rack cabinet. Refer to the documentation that comes with your rack cabinet for the weight of a loaded rack cabinet. · Verify that all door openings are at least 760 x 2032 mm (30 x 80 in.). · Ensure that all devices, shelves, drawers, doors, and cables are secure. · Ensure that the four leveling pads are raised to their highest position. · Ensure that no stabilizer bracket is installed on the rack cabinet during movement. · Do not use a ramp that is inclined at more than 10 degrees. · When the rack cabinet is in the new location, complete these steps. ­ Lower the four leveling pads. ­ Install stabilizer brackets on the rack cabinet or in an earthquake environment bolt the rack to the floor. ­ If you removed any devices from the rack cabinet, repopulate the rack cabinet from the lowest position to the highest position.
xxviii Dell EMC ML3 Tape Library: User's Guide

· If a long-distance relocation is required, restore the rack cabinet to the configuration of the rack cabinet as you received it. Pack the rack cabinet in the original packaging material, or equivalent. Also, lower the leveling pads to raise the casters off the pallet and bolt the rack cabinet to the pallet. (R002)

Physical numbering of storage slots starts with the left magazine of the lowest module of your library. As modules are added above this module, the numbering continues, starting with the lower left slot of the left magazine, and adding 40 storage slots for each additional module.
Note: For libraries with serial numbers before 7800K0K, the slots in the lowest row (1, 6, 11, 16, 21, 26, 31, 36) of the bottom module are inaccessible, and can contain a 4-slot I/O station only.
Each module can be configured to contain an I/O Station, or one I/O Station can be accessed by several modules. I/O Stations consist of five slots in the front column of the right magazine of each module, except for the lowest module. To enable or disable I/O Stations, go to Library > Modules and Magazines > Actions > Enable or Disable I/O Station in the Management GUI.
Important: Ensure that no tapes are in the slots before the I/O Station is enabled or disabled.
Accessor
The accessor is composed of several components: robotic assembly, spooling mechanism, and bar code reader.
· The robotic assembly has fingers that enable it to grab tape cartridges and move them to and from the I/O station, storage slots, and drives.
· The spooling mechanism has a cable that extracts and retracts based on movement of the robotic assembly. This cable provides communication between the robotic assembly and the library main board.
· The high-speed bar code reader is a part of the Base Module. The bar code reader provides inventory feedback to the host application, Operator Panel display, and Management GUI by reading cartridge bar code labels. The library stores the customized inventory data in memory. Library firmware supports a 6

10 Dell EMC ML3 Tape Library: User's Guide

or 8 character volume serial number (VOLSER) on the bar code label on the tape cartridge. It is highly recommended to use bar code labeled cartridges. See "Labeling tape cartridges" on page 160.
Note: For libraries with S/N 7800K0K and higher, review the "Minimum firmware levels for common library features" on page iii.
Power supply
The library provides a single power supply with each library. However, a secondary redundant power supply for the base module can be added. In addition, each expansion module with drives installed requires a power supply.

The LTO tape drives communicate with the library through an internal Ethernet interface. For enhanced performance, the LTO tape drives include speed matching, channel calibration, and power management. Speed matching dynamically adjusts the drive's normal native (uncompressed) data rate to the slower data rate of a server. Channel calibration customizes each read/write data channel for optimum performance. The customization enables compensation for variations in the recording channel transfer function, media characteristics, and read/write head characteristics. Power® management reduces the drive's power consumption during idle power periods.

Control path drives
A control path is a logical path to the library.
A control path is the path for SCSI Medium Changer commands that are sent by a server to control a specific logical library. The library has no direct SCSI connection to a host server. When a software host server communicates with the library, it sends the communication by way of a tape drive. The tape drive is designated as a control path drive.

Mixed drives
All supported generations of LTO tape drives and cartridges can be in the same physical library and within a single module.
This library supports a mixture of LTO drive types in a logical library. Some independent software vendors (ISVs) support mixed drive types within a logical library and other do not. Some ISVs that support mixed drive types might have restrictions. For details, contact your ISV.
Figure 17 on page 13 shows examples of methods for mixing LTO drive types in a logical library.

Physical and logical addresses of drives
The library assigns each tape drive a unique address to indicate its physical and logical location.
The library assigns each tape drive a unique address to indicate its physical location, which is shown in Figure 22 on page 15. The physical numbering is bottom up on all drives. This information is shown on the Drives page of the Management GUI.

Figure 22. Physical numbering of drives The library assigns each tape drive a SCSI element address that consists of a value that defines a logical location in the library to the SCSI interface. It is assigned and used by the application when the host server processes SCSI commands. The SCSI element address for a drive is unique to the location of the drive. It does not vary based on other drives in the library. See "Library partitioning" on page 57.
Chapter 1. Overview 15

Supported tape cartridges
This library supports LTO tape cartridges. Within the library, the supported LTO tape drives use the following cartridge types: · LTO8 Data Cartridge · LTO8 WORM Data Cartridge · LTO M8 Data Cartridge · LTO7 Data Cartridge · LTO7 WORM Data Cartridge · LTO6 Data Cartridge · LTO6 WORM Data Cartridge · LTO5 Data Cartridge · LTO5 WORM Data Cartridge · LTO4 Data Cartridge · LTO4 WORM Data Cartridge · Universal LTO Cleaning Cartridge For information, see Appendix C, "LTO media," on page 157.
Library functions
The library provides many specific functions, such as random or sequential operating mode, encryption, library sharing, path failover, and alerts and logging.
Random and Sequential Logical Library modes
A Logical Library can be configured in one of two modes: Random and Sequential.
Random Mode Random Mode is intended to be used by host applications that support SCSI media changer devices. Random Mode is the default. In Random mode, · The host application chooses the cartridges that are moved to the drive. · I/O slots provide the flexibility for the user to add and remove cartridges and the host application is
automatically notified of these changes. · Multiple drives can be assigned to provide parallel processing data operations and redundancy in case
of failure.
Sequential Mode Sequential Mode is intended to be used by host applications that aren't supporting SCSI media changer devices but need to get another cartridge loaded if the current cartridge is full. In Sequential Mode, · The library predefines the sequential order that the cartridges are moved to the drive. · I/O slots are hidden as they aren't assignable to a logical library with sequential mode enabled. · Only one drive can be assigned to a logical library with sequential mode enabled. · There's no control path drive and no media changer device is configured to the host server. Options to consider when Sequential Mode is chosen:
16 Dell EMC ML3 Tape Library: User's Guide

· Basic Function - To initiate use of cartridges, the user issues a Move Cartridge command to the drive through the Management GUI. After the load, the host application can begin data I/O activity. When the host application unloads the drive, the library moves the next cartridge into the drive. This behavior is implicit, unless otherwise defined by selection of another option.
· Loop Option - If a move sequence ends because no more cartridges are available in the current logical library, the sequence starts again by loading the first cartridge of the logical library. This option can be chosen with or without the Autoload function.
· Autoload Option - If enabled, the library loads the first cartridge of the logical library to the Sequential Mode tape drive during library startup after inventory scan is finished. This option changes the implicit behavior of the Basic function. This option can be chosen with or without the Loop option.
If storage slots are configured to I/O slots after assignment to a Sequential Mode logical library, they are still considered valid available slots and are used for movements. This option stays until you run the expert wizard again, and then these I/O slots no longer appear in the list of available slots. Finishing the expert wizard then sets the new slot assignment and these I/O slots can no longer be used for movements.
To enable sequential mode, click the Enable Sequential Mode check box in the Basic Logical Library Wizard or Expert Logical Library Wizard.
Encryption
All supported tape drives in this library support encryption.
The encryption enabled drive contains the necessary hardware and firmware to encrypt and decrypt host tape application data. Encryption policy and encryption keys are provided by the host application or host server. A drive digital certificate is installed at manufacturing time. Each drive receives a unique serial number and certificate. The T10 application might validate each drive instance by checking the drive's digital certificate.
The library provides these options.
1. Encryption disabled 2. Application Managed Encryption (AME) 3. Library Managed Encryption (LME). LME is a built-in feature. For configuration details, see
"Configuring Library Managed Encryption" on page 72.
The default is Application Managed Encryption.
Enabling library-managed encryption on a Dell EMC ML3 is a six-step process.
1. Upgrade the library and drive firmware to the current versions. The firmware can be found at www.Dell.com/support.
2. Library-managed encryption on the library is already activated and cannot be deactivated.
If issues occur with the library-managed encryption on the library, go to http://www.dell.com/ tapeautomation for information on resolving the issue. If your issue is not resolved, contact Dell technical support. 3. Configure library-managed encryption on your library. 4. Install the IBM SKLM application on the server that is designated as the key manager. See IBM SKLM Knowledge Center for information. 5. Configure the IBM SKLM application. See IBM SKLM Knowledge Center for information. 6. Start the IBM SKLM application. See IBM SKLM Knowledge Center for information.
Note: All encryption settings must be configured or reverified in the drive after any library or drive reset. A new drive might be added or an existing drive might be swapped with another drive.
Chapter 1. Overview 17

Library sharing
The library can be configured into one or more logical libraries that can be shared by multiple applications.
It is advantageous to be able to share a single physical library between heterogeneous or homogeneous applications. However, some applications (and some servers) do not allow for sharing a library between systems.
The library Management GUI provides two methods for logical library configuration.
1. A quick configuration for a simple one logical library configuration
2. An advanced configuration action for a multiple logical library configuration
Note: When any number of drives are loaded, a warning message appears when the Manage Logical Library (Expert Mode) wizard is accessed.
The second method gives the ability to create configurations that enable the library to process commands from multiple heterogeneous applications (such as a Windows application) and multiple homogeneous applications (for example, the same application run by several System p servers). See "Advanced library configuration" on page 56.
Control path failover, Data path failover, and load balancing
The path failover feature ensures the use of a redundant communication path when the primary path fails.
Command failures and time outs are costly. You want your library to run smoothly and efficiently. Path failover capabilities allow the device driver to resend a command to an alternate path. The alternate path can include another host bus adapter (HBA), Storage Area Network (SAN), or library control path drive. The device driver initiates error recovery and continues the operation on the alternate path without interrupting the application.
Path failover and load balancing are built-in features that are enabled by using a purchased license. The path failover feature can be ordered from the factory, or you can order it as a field upgrade. The path failover feature is activated on the Management GUI. To order features, contact your Sales Representative or Business Partner.
Two types of path failover capabilities exist: control path failover (CPF) and data path failover (DPF). Control refers to the command set that controls the library (the SCSI Medium Changer command set on LUN 1 of the tape drives). Data refers to the command set that carries the customer data to and from the tape drives (the SCSI-3 Stream Commands (SSC) device on LUN 0 of the tape drives). Path failover means the same thing in both. Path failover is where redundancy is in the path from the application to the intended target (the library accessor or the drive mechanism), the device driver transparently fails over to another path in response to a break in the active path.
Both types of failover include host-side failover when configured with multiple HBA ports into a switch. But CPF includes target-side failover through the control paths that are enabled on more than one tape drive. DPF includes target-side failover for the dual-ported tape drives that are supported by the library.
DPF includes load balancing of the HBAs because the channel is a data-intensive path (the control path carries little data, so load balancing is not an issue). The dynamic load balancing support optimizes resources for devices that have physical connections to multiple HBAs in the same machine. When an application opens a device where multiple HBA paths are configured, the device driver determines which path has the HBA with the lowest usage and assigns that path to the application. When another application opens a different device with multiple HBA paths, the device driver again determines the path with the lowest HBA usage and assigns that path to the second application. The device driver updates the usage on the HBA assigned to the application when the device is closed. Dynamic load balancing uses all HBAs whenever possible and balances the load between them to optimize the resources in the machine.
Both CPF and DPF require the use of the current device driver. They are supported exclusively with products that bear the Dell logo on the operating systems that is indicated in Table 14 on page 19.
Table 14 on page 19 summarizes the differences between CPF, DPF, and load balancing.

Alerts and logging
The library sends alerts about the library and attached tape drives, and offers audit-logging to track user actions.
· TapeAlert Support: The tape library is compatible with TapeAlert technology, which provides error and diagnostic information about the drives and the library to the host application. The library provides this error and diagnostic information as TapeAlert flags that are reported to the application by the SCSI LOG SENSE command. See "TapeAlert flags" on page 105.
· Email (SMTP - Simple Mail Transfer Protocol) Notifications: The library can configure email notification of library events. The library must have network access to an SMTP server. See "Locating Management functions" on page 63.
· Remote Logging (rsyslog): The library can send syslog (system log) notifications to a configured remote (rsyslog) server. When system events occur, the ML3 tape library creates a log of these events. With this notification feature configured, the library sends a notification of the event to the syslog server. The syslog server keeps its own log of system events. (The syslog server is a customer-provided server.) See "Locating Management functions" on page 63.
· SNMP Support: The Simple Network Management Protocol (SNMP) allows the library to send alerts over a LAN network to a monitoring server.
Occasionally, the library might encounter situations that you want to know about. These situations can be conditions that affect the library performance, such as an open door that causes the library to stop. You might also want to log user actions, such as a cartridge move or export that is initiated from the Management GUI. SNMP messages can alert you of these conditions.
The library provides a standard TCP/IP protocol that is called SNMP to send alerts about conditions over a TCP/IP LAN network to an SNMP monitoring server. These alerts are called SNMP traps. Using the information that is supplied in each SNMP trap, the monitoring server (together with customer-supplied software) can alert operations staff of possible problems or operator interventions that occur. Many monitoring servers can be used to send email or pager notifications when they receive an SNMP alert. See the manual for your network management application.

Chapter 1. Overview 19

The monitoring server must be loaded with systems management software that can receive and process the trap. SNMP supports a get and get-response mechanism for an operator to gather more information about a problem or query the library about its status. Through a monitoring server, the operator enters a "get" using SNMP to request information about the library. A get-response is the information that is provided in response to the get. This type of support generally requires an up-todate library Management Information Base (MIB). The SNMP server's MIB contains units of information that specifically describe an aspect of a system, such as the system name, hardware number, or communications configuration. SNMP Notification Levels SNMP provides various levels of notification about specific library events and user actions. ­ Inactive ­ No events are sent. ­ Critical ­ Only critical events are sent. ­ + Warnings ­ Only critical and warning events are sent. ­ + Configuration ­ Only critical, warning, and configuration events are sent. ­ + Information ­ All events are sent. Simple Network Management Protocol (SNMP) audit logging provides logging information about specific tape library user actions. To configure SNMP, see "Locating Management functions" on page 63.
Host connectivity
The library is supported by a wide variety of servers, operating systems, and adapters. There are many ways to determine the servers and software that support this library. Compatible servers and software These attachments can change throughout the lifecycle of the product. To determine the newest attachments, or to get a comprehensive list of compatible software, do one of the following actions. · For a list of compatible software, operating systems, and servers for LTO tape drives, see
www.Dell.com/support. Notes: 1. Dell does not provide application software with this library. To order software, contact your sales
representative, Business Partner, or an independent software provider. 2. If you attach your library to a server with non-Dell software, contact your software vendor for a
matrix of compatible hardware, software, firmware revisions, and adapter cards. Note: Dependent on the use of Random or Sequential Mode, the library might require an HBA with multiple LUN supports. Also, multiple LUN supports must be enabled on the host computer. When multiple LUN supports are not enabled, the host computer can see the tape drive, but not the library. See "Random and Sequential Logical Library modes" on page 16. Supported device drivers Dell provides device driver support for the LTO tape drives, and the robotics in this library. Dell maintains the current levels of device drivers and driver documentation on the web. Go to www.Dell.com/support and follow the steps to access this material.

Network connectivity
This library supports various browsers and interfaces.
Supported browsers Dell supports higher versions of the browsers if the vendors don't remove or disable functions that the product relies upon. For browser levels higher than the versions that are certified with the product, customer support accepts usage-related and defect-related service requests. As with operating system and virtualization environments, if Dell support can't re-create the issue in the lab, the client might be asked to re-create the problem on a certified browser version to determine whether a product defect exists. Defects aren't accepted for cosmetic differences between browsers or browser versions that don't affect the functional behavior of the product. If a problem is identified in the product, defects are accepted. If a problem is identified with the browser, Dell might investigate potential solutions or workarounds that the client can implement until a permanent solution becomes available.
Supported interfaces This tape library supports the Gigabit Ethernet interface in either auto negotiation or fixed modes of 10 Mbps, 100 Mbps, and 1 Gbps by using half or full duplex. The library supports the following TCP/IP protocols: IPv4 and IPv6 support
This tape library supports Internet Protocol (IP) addresses in both IPv4 and IPv6 format. Both the integrated management console (IMC) and the management GUI allow the definition of IPv4 and IPv6 addresses. The key proxy determines the IP version that is used and presents the correct IP address and parameters to the IP Stack. Simple Network Management Protocol (SNMP) SNMP traps are supported for drive and library events. SNMP management query functions are supported by using a standard Management Information Block (MIB). Hyper Text Transfer Protocol (HTTP) An embedded web server provides a management GUI for library management and query capabilities. Secure Socket Layer (SSL) The tape library supports SSL, a protocol for transmitting private documents through the internet. Key Management Interoperability Protocol (KMIP) Used for communicating with the IBM® Security Lifecycle Key Manager and other security key management software. Simple Mail Transfer Protocol (SMTP) The tape library supports SMTP for sending email alerts. Network Time Protocol (NTP) The tape library supports NTP for external time-and-date synchronization. Lightweight Directory Access Protocol (LDAP) The tape library supports LDAP for centralized authentication. Domain Name System (DNS) The tape library supports DNS for flexible IP addressing. Dynamic Host Configuration Protocol (DHCP) The library supports DHCP for automatically providing an Internet Protocol (IP) host with its IP address and other related configuration information, such as the subnet mask and default gateway.

Contamination

Requirement

Gaseous contamination

Severity level G1 as per ANSI/ISA 71.04-19851, which states that the reactivity rate
of copper coupons shall be fewer than 300 Angstroms per month (Å/month,  0.0039 µg/cm² - hour weight gain)2. In addition, the reactivity rate of silver coupons shall be less than 300 Å/month ( 0.0035 µg/cm² - hour weight gain)3. The reactive
monitoring of gaseous corrosivity should be conducted approximately 5 cm (2 in.) in
front of the rack on the air inlet side at one-quarter and three-quarter frame height
off the floor or where the air velocity is much higher.

Particulate contamination

Data centers must meet the cleanliness level of ISO 14644-1 class 8. For data centers without airside economizer, the ISO 14644-1 class 8 cleanliness might be met by the choice of the following filtration:

· The room air might be continuously filtered with MERV 8 filters.
· Air entering a data center might be filtered with MERV 11 or preferably MERV 13 filters.

For data centers with airside economizers, the choice of filters to achieve ISO class 8
cleanliness depends on the specific conditions present at that data center. The
deliquescent relative humidity of the particulate contamination should be more than 60% RH.34.Data centers must be free of zinc whiskers5.

Notes:
1. ANSI/ISA-S71.04. 1985. Environmental conditions for process measurement and control systems: Airborne contaminants, Instrument Society of America, Research Triangle Park, NC, 1985.
2. The derivation of the equivalence between the rate of copper corrosion product thickness growth in Å/ month and the rate of weight gain assumes that Cu2S and Cu2O grow in equal proportions.
3. The derivation of the equivalence between the rate of silver corrosion product thickness growth in Å/month and the rate of weight gain assumes that Ag2S is the only corrosion product.
4. The deliquescent relative humidity of particulate contamination is the relative humidity at which the dust absorbs enough water to become wet and promote ionic conduction.
5. Surface debris is randomly collected from 10 areas of the data center on a 1.5-cm diameter disk of sticky electrically conductive tape on a metal stub. If examination of the sticky tape in a scanning electron microscope reveals no zinc whiskers, the data center is considered free of zinc whiskers.

Network requirements
The library supports an independent customer network. It is the customer's responsibility to provide the proper length Ethernet cable for this connectivity. The base module controller card has two Ethernet ports, which offer primary and redundant customer network connectivity. See "Rear panel" on page 8. These connections allow remote viewing and management of the library with the Management GUI. Note: Have your network settings handy to use for entering on the Operator Panel. Your network settings can also be stored as hardcopy on Appendix A, "Library Configuration Forms," on page 146. The secondary Ethernet port might be used for service. Three models are available for connection: · No Ethernet port - Service personnel can connect a laptop to the customer network to use the
Management GUI. · Dedicated secondary Ethernet port - The secondary network port that is dedicated only for service
personnel to connect a laptop directly to the library. · Secondary Ethernet port - The secondary network port can be disconnected and service personnel can
use it to connect a laptop directly to the library.
IP range selection For internal communication between modules, the tape library uses an Ethernet connection with an internal IP address range. To prevent any conflict between the internal IP address range and the external IP addresses, you must select the internal IP range. Choosing the Internal IP address range, and also entering the external IP address information is part of the initial setup of the library.
Host requirements
The library requires attachment to supported SAS or FC HBAs. The library requires attachment to supported SAS or FC HBAs. See "Host connectivity" on page 20.
Static Sensitive Risk of damage to devices · A discharge of static electricity damages static-sensitive
devices or micro circuitry. · Proper packaging and grounding techniques are necessary
precautions to prevent damage.
Follow these general guidelines. · Check with a system administrator before the host computer is powered off. · For a SAS library, confirm availability or install a SAS HBA that supports multiple LUNs. · For a direct-attach Fibre Channel library, confirm availability of installation of an FC HBA. · For connection of a Fibre Channel library through a compatible switch, verify that sufficient ports are
available.
Persistent binding to ensure SCSI ID assignment When a server is booted, devices are discovered and assigned SCSI target and LUN IDs. It is possible for these SCSI assignments to change between boots. Some operating systems do not guarantee that devices are always allocated the same SCSI target ID after rebooting. Also, some software depends on
32 Dell EMC ML3 Tape Library: User's Guide

this association, so you do not want it to change. The issue of SCSI ID assignment is addressed by persistent binding. Persistent binding is an HBA function that allows a subset of discovered targets to be bound between a server and device. Implemented by a worldwide node name (WWNN) or worldwide port name (WWPN), persistent binding causes a tape drive's WWNN to be bound to a specific SCSI target ID. After a configuration is set, it survives restarts and any hardware configuration changes because the information is preserved. If a drive must be replaced, the new drive assumes the WWNN of the old drive because the WWNN for the drive is location-dependent within the library. Because the WWNN does not change, persistent binding does not need changing, thus preventing a potential outage.

Advanced library configuration
To create and manage multiple logical libraries, utilize the advanced logical library function.
Overview
Overview of advanced features such as multipath architecture, multiple logical libraries, and multiple control paths.
Multipath architecture The multipath architecture feature of this tape library allows Open Systems applications to share the robotics of the library. See "Library sharing" on page 18.
The library features storage area network (SAN) ready multipath architecture. This architecture allows homogeneous or heterogeneous Open Systems applications to share the library's robotics without middleware or a dedicated server (host) acting as a library manager. The SAN-ready multipath architecture makes sharing possible by partitioning the library's storage slots and tape drives into logical libraries. Servers can then run separate applications for each logical library. This partitioning capability extends the potential centralization of storage that the SAN enables. Partitioning also provides investment protection if your application does not support the mixing of drive generations and media in the same logical library.
The multipath architecture of this library is designed to provide the capability to share the library robotics. The sharing is accomplished first by partitioning the library into multiple logical libraries (up to the number of drives installed). Then, each logical library is assigned its own separate and distinct drives, storage slots, and control paths. Input/output (I/O) slots are shared on a first-come-first-serve basis. This type of partitioning is designed to allow heterogeneous applications to share the library robotics independent of each other. Cartridges under library control are not shared between logical libraries, nor are they allowed to be moved between logical libraries. An example of heterogeneous sharing is a
56 Dell EMC ML3 Tape Library: User's Guide

Microsoft Windows application that is using the drive and storage slots of one logical library, while a UNIX application uses the drive and slots of another logical library. See "Mixed drives" on page 12.
Multiple logical libraries
A library can be partitioned into multiple logical libraries to enable simultaneous data backup and restore tasks from different applications. For example, you can create multiple logical libraries so that is processes
· Commands from Application 1 (about Department A) in Logical Library 1 · Commands from Application 2 (about Department B) in Logical Library 2 · Commands from Application 3 (about Department C) using Sequential Mode in Logical Library 3
In this configuration, the tape drives and cartridges of each logical library are dedicated to that library and are not shared among other libraries and applications. Commands that are issued by the applications travel to the library through unique control paths or sequential mode processing by the library. So, the data processing for Department A is confined to the tape drives and cartridges of Logical Library 1. Processing for Department B is confined to the tape drives and cartridges of Logical Library 2, and so forth.
For applications that do not support mixed drive types and media within the same logical library, partitioning the library into multiple logical libraries provides the capability to keep them separate. For example, you can partition the following tape drives and their media into multiple and separate logical libraries:
· LTO 8 · LTO 7 · LTO 6
Multiple control paths
With this tape library's multipath architecture, in addition to creating multiple logical libraries, you can configure any logical library to have more than one control path. A control path is a logical path into the library through which the library receives standard SCSI Medium Changer commands to control the library operations.
Note: No SCSI Medium Changer is configured when the logical library is enabled as Sequential Mode
Multiple control paths reduce the possibility of a failure in one control path to cause the entire library to become unavailable. Also, when you configure more control paths, more library-sharing configurations and options are possible. Access to the library is on a first-come, first-served basis. Each control path for a logical library can accept commands while the library is in use by another control path.
Multiple control paths for control path failover
This tape library offers an optional control path failover feature. See "Library sharing" on page 18 and "Control path failover, Data path failover, and load balancing" on page 18.
Use of the control path failover feature further reduces the possibility of a failure in one control path to cause the entire library to become unavailable.
The control path failover feature (feature code 1682) enables the host device driver to resend a command to a different control path for the same logical library.
Library partitioning
Libraries that contain at least two drives can configure two logical libraries. It is possible to configure up to 21 logical libraries in the library (up to the number of drives installed). In a partitioned library, the Operator Panel reports only the status of logical library 1 in the main menu because of space limitations. The user must go to the logical libraries status in the Operator Panel to get the information about the additional library partitions. The Management GUI provides a Logical Library Graphical View.
Chapter 3. Installing 57

Partitioning of libraries With full-height or half-height physical drives, physical numbering is bottom up for all drives. For example, if you replace a half-height drive in Figure 22 on page 15, the drives are still numbered 1-4. If you add a drive in any of the slots in between drives numbered 1 and 4, the physical numbering changes and is still numbered bottom up. Important: A full-height drive can be installed in a module in the lower two slots only.
Configuration of a 1-logical library system A one logical library system contains all drives present in any drive positions, and it contains all the slots.
Configuration of multiple logical libraries A library with multiple logical libraries must have a drive for each logical library and at least five slots. Drives can be in any location in the library. It is best to have drives that are located near the slots that are assigned to the same logical library to minimize accessor movement and maximize performance.
SCSI element-addressing A logical library assigns SCSI element addresses to drives, storage slots, I/O slots, and the accessor. For each element type (drive, storage, I/O), the SCSI element address can be viewed on the Management GUI. While SCSI addressing follows the same method as physical location-numbering, this action depends on the Advanced Logical Library configuration. Drive numbering is from bottom to top. Storage slot-numbering is from left magazine (front to back, bottom to top) to right magazine (back to front, bottom to top). IO slot-numbering is from bottom to top. Accessor is single number. Note: When the number of drives in your library are reduced, update the logical library configuration. This action removes all event notifications that indicate a drive is missing. Updating the logical library configuration might change the SCSI element addressing.
Verifying the host connection
Procedure to verify the connection between the host computer and the library. To verify the connections between the host computer and the library 1. Install the application software and drivers that are compatible with the library. Backup software
packages might require extra software or licensing to communicate with the robotics. 2. Verify the connection between the library and the host by using the host server's operating system
utilities. Or, use the Tape Diagnostic Tool (ITDT) to verify the communication between library and host. See "The ITDT firmware update, dump retrieval and drive test tool " on page 80. See "Host connectivity" on page 20 for compatible servers and software.

Chapter 4. Managing
Four user roles are described, and each user role has its specific functions.
· Administrator - This role provides access to the administrator functions on the Management GUI. There is a default administrator password adm001 for the first login. The administrator password can be changed on the Local Users page.
· Monitor - This role allows access to library status information and does not allow access to configuration, maintenance, or operation features. Setting a monitor password restricts access to status information to only those users who know the monitor password. Passwords for the Monitor role can be set or changed by the administrator.
· Superuser - This role has same access rights as the Administrator role, except the ability to access the Local Users and Remote Authentication (LDAP Authentication and Kerberos Authentication) pages. In addition, it is possible to do cartridge moves and open magazines and I/O Stations. Passwords for the Superuser role can be set or changed by the administrator.
· Service - This role provides access to the service functions on the Management GUI. Passwords for the Service role can be set or changed by the administrator.
Notes:
· Monitor, Superuser, and Service user IDs must be enabled by the library administrator. These accounts are disabled by default.
· For a complete description of the menu items available to each user role, see Appendix B, "Management GUI functions and roles ," on page 151.
The Management GUI
With the Management graphical user interface (GUI), you can monitor, configure, and operate most library functions from a web browser.
When possible, use the Management GUI as the primary library interface. The web interface provides access to more features, includes online help, and is intuitive to use.
Before the Management GUI can be used, you need to log in and configure the library network settings with the Operator Panel. This action can be done during Initial Setup. See "The Initial Setup process" on page 53.
Logging in with the Management GUI
1. Open a supported web browser and enter the IP address of the library in the browser's address bar. 2. Type in the username (administrator or other administrator-created user) and the password. Click
Login.
Note: For initial login, type administrator and the password adm001. You must change the password after the initial login. Your new password must have these characteristics:
· 8 characters long · At least one lowercase alphabet character · At least one uppercase alphabet character · At least one numeric character · No more than two consecutive characters
Note: Only one person (on Operator Panel or Management GUI) can be logged in to the library at a time. If another person is already logged in when you try to log in, a dialog box appears asking if you want to log off the other user.

Methods of cleaning drives
Automatic cleaning of tape drives is disabled by default in the library. However, automatic cleaning of tape drives is recommended for this library. It is also possible to initiate manual or host cleaning methods.
The head of every tape drive in the tape library must be kept clean to prevent errors that are caused by contamination. To help you keep the drives clean, Dell provides a cleaning cartridge with the library. The library uses the cleaning cartridge to clean the drive with whatever cleaning method that you choose. In all methods, cleaning is done after the data cartridge is unloaded from the drive and before the next load.
If you put the cleaning cartridge into a storage slot that is assigned to a logical library, it is visible to any hosts that are associated with that logical library. If you don't want the cleaning cartridge visible to any hosts, put it into a storage slot that is not assigned to any logical libraries.
It is the operator's responsibility to monitor cleaning cartridge usage and replace cleaning cartridges as necessary. This tape library provides multiple ways to monitor and manage cleaning cartridges. If SNMP traps are enabled, a trap is generated when a cleaning cartridge expires. It is also possible to use the Management GUI to monitor the cleaning cycles that remain on a cleaning cartridge.
Three methods of cleaning are available.
Automatic cleaning Automatic cleaning enables the library to automatically respond to any tape drive's request for cleaning and to begin the cleaning process. The cleaning process is transparent to any host application that uses the library.
Select Auto Clean to enable the auto cleaning feature. When enabled, the library automatically initiates a cleaning operation when media is unloaded from a drive that requires cleaning instead of creating a warning event when a drive requires cleaning. For reliable operation, enable Auto Clean for each logical library and ensure that the library has a valid cleaning cartridge.
It is preferred to put the cleaning cartridge into a storage slot that is not assigned to a logical library. If you put the cleaning cartridge into a storage slot that is assigned to a logical library, it is visible to any

70 Dell EMC ML3 Tape Library: User's Guide

hosts that are associated with that logical library. If you don't want the cleaning cartridge to be visible to any hosts, put it into a storage slot that is not assigned to any logical libraries.
When a cleaning operation is initiated, the library first attempts to use an unexpired cleaning cartridge from the same logical library as the tape drive. If the logical library does not contain an unexpired cleaning cartridge, the library attempts to use an unexpired cleaning cartridge from a storage slot that is not assigned to a logical library. The library does not use a cleaning cartridge from a different logical library. When auto cleaning is enabled, ensure that each logical library has an unexpired cleaning cartridge. Or, place at least one unexpired cleaning cartridge into a storage slot that is not assigned to a logical library.
After the initial configuration, Auto Clean can be turned on or off by accessing the Logical Library Wizard Expert Mode.
1. Go to Library > Logical Libraries > Actions > Manage Logical Library (Expert Mode).
2. Select the logical library, then click Edit.
3. Click Next to go to the General Settings screen.
4. Check or clear Auto Clean, then click Next on the subsequent screens.
5. If a change was made, click Finish and the Logical Libraries are reconfigured. If no changes were made, click Cancel.
Note: Dell recommends enabling the Auto Clean function on the library. With the Auto Clean function enabled, drive cleaning occurs automatically. The only time Auto Cleaning must be disabled is when your backup application requires that it has control.
Manual cleaning Manual cleaning requires that you select a menu option from the Management GUI to clean one or more of the tape drives. Manual cleaning is always supported.
Host cleaning Host cleaning enables the backup application to define and control the cleaning process. Automatic and manual cleaning use the CLNxxx VOLSER. It is mandatory to put the cleaning cartridge into a storage slot that is assigned to a logical library. The host needs to "recognize" that the cleaning cartridge is available for use.
Note: For tape cartridge information, see "Supported tape cartridges" on page 16.

Accessing cartridges
Each magazine has a button that provides an easy way to open a magazine.
See "Front panel" on page 7.
Each module can be configured to have a portion of the right magazine that is designated as an I/O station or this option can be disabled.
· To open the I/O station, press the magazine button for less than 3 seconds. · To open the entire magazine, press the magazine button for more than 3 seconds.
Notes:
1. If a magazine is opened, no other magazines or I/O stations can be opened. 2. If during the magazine open process the magazine is not opened within 30 seconds, the magazine
locks. 3. The user must pull out the magazine, as the magazine does not eject.
The LED also provides an indicator of the current state of that magazine.

Configuring Library Managed Encryption
Library-Managed Encryption (LME) is a built-in feature that is factory-enabled.
Two versions of Library-Managed Encryption are available for configuration.
· Key Management Interoperability Protocol (KMIP) Encryption (v1.2) · Security Key Lifecycle Manager (SKLM) for z/OS® Encryption
Access the wizard from the Actions menu with the Manage Encryption option. The Library Managed Encryption Licensed Feature is already activated on your library, and can't be deactivated. However, the feature must be configured before LME can be used.
Notes: Before you run the Encryption wizard.
· Confirm that the Library-Managed Encryption license is activated on the Settings > Library > Licensed Features page.
· Verify that the server is available on the network and is configured for use with this library. For information on configuring servers for use with the library, see the server documentation.
Note: If you plan to use the IBM Security Key Lifecycle Manager (SKLM), go to "Related Publications" on page xxxi for information on setup and configuration. · If Library Encryption settings are cleared and reconfigured, you're required to accept the new certificate on the server when the Library Self-Signed Certificate is used.

Key Management Interoperability Protocol (KMIP) Encryption
1. In the Actions menu, click Manage KMIP Encryption to start the wizard. 2. The Logical Library Selection screen displays the KMIP configuration options that can be set as the
default for all logical libraries, or on a per logical library basis. The second section provides the option to copy the KMIP configuration settings to all logical libraries (default) or to specified logical libraries.
3. The Wizard Information screen displays information about the wizard. On this screen, it's also possible to Reset Encryption Settings. If the library configuration is complete and the KMIP server is available on the network, click Next.
4. The Certificate Option screen displays the different certificate options that can be used to establish a secure communication to the KMIP server. You can select from the following options:

Key Path Diagnostics The Key Path Diagnostic test checks all communication paths to ensure that a key can be transmitted from the encryption key servers to the drive to properly encrypt and decrypt the tape cartridges. The test consists of two parts. The first part, the drive test, verifies whether the communication between library and drive is working properly. This test is run only on the drives that are configured to librarymanaged encryption (LME). The second part verifies the communication between the library and the encryption key servers. If the secondary ethernet port is enabled and configured, the tests are run on both ports separately. The test consists of four subtests: · Ping
This test checks if the key server can be reached. If ICMP requests are blocked on the server side, this test fails as well. Therefore, the following tests are run regardless the result of the ping test. · SSL/TLS This test tries to establish a SSL/TLS connection with the key server. If this test fails, the following tests are skipped because they would also fail. This test is skipped if SSL/TLS is not enabled. · Key Server Login This test is run only in combination with a KMIP encryption server since SKLM currently does not support login. If this test fails, the following Key Retrieval test is skipped because it would also fail. · Key Retrieval This test requests a key from the encryption server. For SKLM servers, a key from the key pool is requested. On other servers, the library acquires a specific diagnostic key.

TapeAlert flags
This section is intended to provide information to the reader about the tape drive by using TapeAlert technology.
All error code and diagnostic information can be accessed from the Management GUI of the library. The drive portion of the Management GUI contains drive error codes. Therefore, it is not necessary to open the Library to access the buttons on the drive. See "Locating Management functions" on page 63 for a complete description of the Management GUI functions and displays.
TapeAlert is a standard that defines status conditions and problems that are experienced by devices such as tape drives, autoloaders, and libraries. The standard enables a server to read TapeAlert messages (called flags) from a tape drive with the SCSI bus. The server reads the flags from Log Sense Page 0x2E. Refer to the Dell Model ML3 Tape Library SCSI Reference?? for library and drive TapeAlert Flag information.
This library is compatible with TapeAlert technology, which provides error and diagnostic information about the drives and the library to the server. Because library and drive firmware might change periodically, the SNMP interface in the library does not require code changes if devices add more TapeAlerts that are not supported today. However, if this issue occurs the Management Information Block (MIB) is written to minimize impact to the SNMP monitoring station. At the time of this writing, the TapeAlert flags correctly represent TapeAlerts that are sent. The MIB file must not be taken to mean that all traps that are defined in the MIB are sent by the library or that they will be sent in the future.

When a drive encounters an error, it provides sense data as a response to the host.
Refer to the Dell Model ML3 Tape Library SCSI Reference?? for library sense data information. Refer to the Dell LTO Ultrium Tape Drive SCSI Reference?? for tape drive sense data information.
In addition, you can use the Tape Diagnostic Tool (ITDT) to further examine data and determine errors. See "The ITDT firmware update, dump retrieval and drive test tool " on page 80.
Drive Error Codes: Single-character display (SCD)
SCD drive error codes give descriptions of the errors and messages that pertain to the drive.
If you encounter problems while the tape drive is running, refer to "Finding event information" on page 75.
The SCD display appears on the inside back of an installed library and can be seen through the front window of an expansion unit. It is seen on the lower center of a full-height drive. Each drive has a status light and single-character display, that when visible provides drive informational and error conditions. The single-character display shows either a single character, a dot (in the lower right of the display), or both.
Note: The SCD can be seen through the windows of expansion units, and for full-height drives only. If you have a base unit without expansion units, or if you have half-height drives, the SCD cannot be seen.
"Single-character display (SCD) codes" on page 112 lists the codes for error conditions and informational messages. If multiple errors occur, the code with the highest priority (represented by the lowest number) displays first. When the error is corrected, the code with the next highest priority displays until no errors remain.

Chapter 5. Troubleshooting 111

The SCD is blank during normal operation.

Single-character display (SCD) codes
Table 38 on page 112 gives descriptions of the errors and messages that pertain to the drive. For troubleshooting tips, see "Troubleshooting Guide" on page 75.
· Make note of the SCD error code before a cartridge is removed or the SCD error code is cleared. · If an error occurred with a cartridge in the drive, eject the cartridge from the drive with the library
Management GUI (see "Locating Management functions" on page 63).

Attention: If the drive detects a permanent error and displays an error code other than SCD , it automatically runs a drive dump. If you force a drive dump, the existing dump is overwritten and data can be lost. After you force a drive dump, do not turn OFF the power to the drive or you might lose the dump data.

Note: The single-character display is blank during normal operation of the tape drive.

Temperature problem. The tape drive detected that the recommended operating temperature was exceeded.
Power problem. The tape drive detected that the externally supplied power is outside the specified voltage limits (the tape drive is not operating).
Firmware problem. The tape drive determined that a firmware error occurred
Note: Do not force a new dump; the tape drive already created one.

Firmware or hardware problem. The tape drive determined that a firmware or tape drive hardware failure occurred.
Note: Do not force a new dump; the tape drive already created one.

Tape drive hardware problem. The drive determined that a tape path or read/write error occurred.
Notes:
· To prevent damage to the drive or tape, the tape drive does not allow a cartridge to be inserted if the current cartridge was successfully ejected.
· Do not force a new dump; the tape drive already created one.

Tape drive or media error. The tape drive determined that an error occurred, but it cannot isolate the error to faulty hardware or to the tape cartridge. Ensure that the tape cartridge is the correct media type. See Appendix C, "LTO media," on page 157.
Ensure tape drive is at the latest firmware version. See "Minimum firmware levels for common library features" on page iii.

Tape drive or library-drive communication error. The tape drive determined that a failure occurred in the tape drive's hardware or in the library-drive connection.

Degraded operation. The tape drive determined that a problem occurred which degraded the operation of the tape drive, but it did not restrict continued use. If the problem persists, determine whether the problem is with the drive or the media.

Note: The drive is usable, though the single-character display continues to indicate an error and the status light flashes amber.

The tape drive needs to be cleaned. See "Locating Management functions" on page 63.

Fibre Channel error. No light is displayed if the drive fiber port does not detect light.

Write operation to a write protected cartridge was attempted. This action includes any attempt to overwrite a WORM protected tape. Ensure that the tape cartridge is the correct media type. See Appendix C, "LTO media," on page 157.

SCD dot
If a drive dump is present while the drive is in maintenance mode, a single red dot illuminates in the lower right corner of the SCD. To download the drive dump, see "Locating Management functions" on page 63 or "The ITDT firmware update, dump retrieval and drive test tool " on page 80.
The SCD dot turns OFF when you obtain a dump or update the drive firmware.
Note: If the drive dump is stored in ROM memory (SCD dot ON solid), the dump is lost when you turn OFF the power or reset the drive.

Status light
The Status light is a light-emitting diode (LED) that provides information about the state of the drive. The light can be green or amber, and (when lit) solid or flashing. Table 39 on page 113 lists the conditions of the Status light and single-character display (SCD) and provides an explanation of what each condition means.

Replacing a Base or Expansion controller card
CAUTION: · Parts can be damaged by electrostatic discharge. Keep
parts in electrostatic containers until needed. Ensure that you are properly grounded when static sensitive components are touched. · You must power off the library to install or replace this part or damage can occur.
Important: Do not replace both the base chassis and the Base Module controller card with repair components in the same procedure. The firmware does not allow the library to operate if both components are replaced at the same time. Critical library information is saved in the controller card and within the chassis. When one is replaced, the data from the original component is transferred to the repair component. If both the base chassis and Base Module controller are replaced, you must power cycle the library between component replacements.
Saving the configuration See "Locating Management functions" on page 63 for instructions on saving configuration settings to a file with the Management GUI or with the Operator Panel. This procedure is done when a Base Module controller card is replaced, or as an extra precaution when both the controller card and the module are replaced. Note: Do not do a Save Configuration on a library that is in a failed state. Save the configuration on a working library only.
Powering off the library Verify that all host processes are idle, then power off the library from the front panel. Depress Power and hold it for 5 seconds. If the library does not complete a soft shutdown, depress and hold Power for 10 seconds. Important: Under normal circumstances, when the library is powered off by using the front Power, the robot automatically parks and locks into the Base Module behind the Operator Panel. If you are given a choice during the power down procedure, choose the default park position. To protect the spooling cable or other sensitive parts, the accessor must be in the Base Module before any modules or drives are removed from the library. If it is not, follow the procedure for returning the accessor to the base module. See "Returning the accessor to the Base Module" on page 137.

Important: Under normal circumstances, when the library is powered off by using the front Power, the robot automatically parks and locks into the Base Module behind the Operator Panel. If you are given a choice during the power down procedure, choose the default park position. To protect the spooling cable or other sensitive parts, the accessor must be in the Base Module before any components are removed from the library. If it is not, follow the procedure for returning the accessor to the base module. See "Returning the accessor to the Base Module" on page 137. 2. Refer to "Preparing to remove the accessor and spooling mechanism from the Base Module" on page 131 for the steps in preparing your library.

Removing or replacing a magazine
It is recommended that you unlock the magazine with the Operator Panel, Management GUI, or the release button on the front panel. If these methods fail, or if a magazine needs to be removed when the power to the device is off, you can release the magazine manually. Only one magazine or I/O station can be open at a time. Note: This procedure is completed more effectively while applications are idle. While the magazine is extended, the library robotic assembly cannot move media. 1. Log in as an administrator. 2. Go to Library > Modules and Magazines. 3. On the Actions menu, click Unlock Magazine.

Appendix C. LTO media

This section provides an overview of LTO media, which is recommended for use with this library. Figure 85 on page 157 shows the LTO data cartridge and its components.

Data cartridges

Use the LTO data and cleaning tape cartridges that are designed for your model of library.
When tape is processed in the cartridges, LTO Tape Drives use a linear, serpentine recording format. The native data capacity and recording format of LTO data cartridges is as follows:

Table 45. Cartridge data capacity and recording formats

Type

Native Data Capacity

Recording Format

LTO8

12 TB (30 TB at 2.5:1 compression) Reads and writes data on 6656 tracks, 32 tracks at a time.

LTO M8

9 TB (22.5 TB at 2.5:1 compression)

Reads and writes data on 3584 tracks, 32 tracks at a time.

LTO7

6 TB (15 TB at 2.5:1 compression) Reads and writes data on 3584 tracks, 32 tracks at a time.

LTO6

2.5 TB (6.25 TB at 2.5:1 compression)

Reads and writes data on 2176 tracks, 16 tracks at a time.

See "Minimum firmware levels for common library features" on page iii for minimum firmware levels for LTO 8 drives and media.

The first set of tracks is written from near the beginning of the tape to near the end of the tape. The head then repositions to the next set of tracks for the return pass. This process continues until all tracks are written and the cartridge is full, or until all data is written.
The cartridge door ( 2 in Figure 85 on page 157) protects the tape from contamination when the cartridge is out of the drive. The tape is attached to a leader pin ( 3 in Figure 85 on page 157) behind the door. When the cartridge is inserted into the drive, a threading mechanism pulls the pin (and tape) out of the cartridge, across the drive head, and onto a non-removable take-up reel. The head can then read or write data from or to the tape.
The write-protect switch ( 4 in Figure 85 on page 157) prevents data from being written to the tape cartridge. For more information, see "Write-Protect switch" on page 162.
The label area ( 5 in Figure 85 on page 157) provides a location to place a label. .
The insertion guide ( 6 in Figure 85 on page 157) is a large, notched area that prevents the cartridge from being inserted incorrectly.

LTO Type M Cartridge (M8)
The LTO Program introduced a new capability with LTO8 tape drives: the ability to write 9 TB (native) on a brand new LTO Ultrium 7 cartridge instead of 6 TB (native) as specified by the LTO 7 format. Such a cartridge is called an LTO 7 initialized LTO Type M cartridge. These LTO Type M cartridges are identifiable by using an automation bar code label that ends with the last 2 characters "M8".

LTO 8 LTO 7, LTO 8

From now on, these cartridges are referred to as L8, M8, and L7.
Only new, unused LTO Ultrium 7 cartridges can be initialized as M8 cartridges. When a cartridge is initialized as M8, it cannot be changed back to L7. Initialized M8 cartridges can be written and read only in an LTO 8 tape drive; LTO7 tape drives cannot read initialized M8 cartridges.
M8 cartridges can be purchased as either preinitialized (also referred to as "labeled and initialized") M8 data cartridges or uninitialized M8 data cartridges (M8 WORM cartridges are not supported). For either option, the bar code label is included. However, the uninitialized M8 data cartridge must first be initialized in tape libraries that support the automatic initialization of uninitialized M8 cartridges while under the control of ISV applications that recognize the "M8" bar code label.
A tape cartridge is initialized when it is first loaded into a compatible tape drive and data is written by the ISV application at the beginning of tape (sometimes referred to as "labeling a tape" or "writing from BOT"). The tape drive then establishes the density of the media.
If an uninitialized M8 cartridge is not initialized in a tape library that supports uninitialized M8 cartridges, then the cartridge might inadvertently and silently be initialized at the L7 density (that is, at a 6 TB native capacity) even if the bar code label states "M8". This action might occur with the usage of stand-alone LTO7 tape drives, stand-alone LTO8 tape drives, earlier LTO8 tape drive firmware, earlier library firmware, or earlier ISV software that does not recognize that M8 cartridges must be mounted only in LTO8 tape drives. M8 cartridges that are inadvertently initialized at the L7 density can continue to be read and written in LTO7 and LTO8 tape drives. However, they remain limited to the 6 TB native capacity.
Note: See "Minimum firmware levels for common library features" on page iii for minimum firmware levels for LTO M8 media.

WORM (Write Once, Read Many) cartridges
Certain records retention and data security applications require a Write Once, Read Many (WORM) method for storing data on tape. LTO drives that are supported by the library enable WORM support when a WORM tape cartridge is loaded into the drive.
WORM media
Because standard read/write media are incompatible with the WORM feature, a specially formatted WORM tape cartridge (see Figure 86 on page 160) is required. Each WORM cartridge has a unique, worldwide cartridge identifier (WWCID), which comprises the unique CM chip serial number and the unique tape media serial number. Ultrium WORM media are two-tone color and silvery gray.
Note: All Dell drive firmware allows the use of WORM media.

Appendix C. LTO media 159

Figure 86. LTO Data and WORM tape cartridges
Data security on WORM media
Certain built-in security measures help ensure that the data that is written on a WORM cartridge do not become compromised. For example · The format of a WORM Tape Cartridge is unlike that of standard read/write media. This unique format
prevents a drive that lacks WORM-capable firmware from writing on a WORM tape cartridge. For LTO 8, native data capacity is 12000 GB and compressed data capacity is 30000 GB. · When the drive senses a WORM cartridge, the firmware prohibits the changing or altering of user data that is already written on the tape. The firmware tracks the last appendable point on the tape.
WORM media errors
The following conditions cause WORM media errors to occur. · Information in the servo manufacturer's word (SMW) on the tape must match information from the
cartridge memory (CM) module in the cartridge. If it does not match, a media Error Code 7 posts on the drive's single-character display (SCD). · Inserting a WORM tape cartridge into a drive that is not compatible with WORM causes the cartridge to be treated as an unsupported medium. The drive reports a media Error Code 7.
Cleaning cartridge
With each library, a specially labeled Cleaning Cartridge is required to clean the drive head. The drive itself determines when a head must be cleaned. It alerts you by lighting the Clean Drive (amber LED) on the Operator Panel. Dell recommends the use of the Auto Clean function on this library. When enabled, the library retrieves the cleaning cartridge, inserts it in the drive that needs cleaning, cleans the drive, then returns the cleaning cartridge to its home slot. To clean the head manually, insert a cleaning cartridge into the tape load compartment. The drive completes the cleaning automatically. When the cleaning is finished, the drive ejects the cartridge, and the library turns off the Clean Drive LED. See "Methods of cleaning drives" on page 70. Note: The drive automatically ejects an expired cleaning cartridge. The Dell Cleaning Cartridges are valid for 50 uses.
Labeling tape cartridges
The bar code reader is a part of the library accessor. The bar code reader reads each cartridge bar code label that identifies the types of cartridge magazines and tape drive that is installed in the library. It also provides inventory feedback to the host application, Operator Panel, and Management GUI. The library stores the customized inventory data in memory. Library firmware supports a 6 or 8-character volume serial number (VOLSER) on the bar code label on the tape cartridge. Having a bar code label on each tape cartridge enables the bar code reader to identify the cartridge quickly, thus speeding up inventory time. Make it a practice to use bar code labels on your tape cartridges.
160 Dell EMC ML3 Tape Library: User's Guide

A bar code label contains:
· A volume serial number (VOLSER) that is human-readable. · A bar code that the library can read.
Note: In a library environment, it is highly recommended to use bar code labels for performance and easily identifiable reasons. This library requires bar code labels.
Your host software might need to track the following information by using the associated bar code.
· Date of format or initialization · Tape's media pool · Data residing on the tape · Age of the backup · Errors that are encountered while the tape is used (to determine whether the tape is faulty).
Important: Misusing and misunderstanding bar code technology can result in backup and restore failures. Use only high-quality labels. Self-printed labels are not recommended as they are often a source of bar code reading issues.
When read by a library's bar code reader, the bar code identifies the cartridge's VOLSER to the library. The bar code also tells the library whether the cartridge is a data cartridge or cleaning cartridge. The bar code includes the two-character media-type identifier:
· L or M identifies the cartridge as an LTO cartridge. · 6, 7, or 8 indicates that the cartridge is the sixth, seventh, or eighth generation of its type. Only LTO 6 or
later cartridges are supported by the DellTM EMC ML3 tape library. · W indicates that the cartridge is a generation 6 WORM cartridge. X indicates that the cartridge is a
generation 7 WORM cartridge, and Y indicates that the cartridge is a generation 8 WORM cartridge.
Figure 87 on page 162 shows a sample bar code label for the LTO Tape Cartridge.
Tape cartridges are ordered with the labels included or with custom labels. The bar code usage for tape libraries must meet predefined specifications. They include (but are not limited to)
· Six or eight (the default) uppercase alphanumeric characters, where the last 2 characters must be L6, L7, M8, or L8 (LW, LX, or LY for WORM cartridges).
· Label and printing to be non-glossy. · Nominal narrow line or space width of 0.423 mm (0.017 in.) · Wide to narrow ratio of 2.75:1. · Minimum bar length of 11.1 mm (0.44 in.)

To determine the complete specifications of the bar code and the bar code label, contact your sales representative. LTO tape cartridges have a recessed area on the face of the cartridge next to the write-protect switch. Use this area for attaching the adhesive-backed bar code label. Place the label only in the recessed label area (see 5 in Figure 85 on page 157). A label that extends outside of the recessed area can cause loading problems in the drive.
Attention: Do not place any type of mark on the white space at either end of the bar code. A mark in this area might prevent the library from reading the label.
Figure 87. Sample bar code label on the LTO8 Tape Cartridge Important: The bar code label must be applied as shown, with the alphanumeric characters on top and the bar codes on the hub side (bottom). Never apply multiple labels onto a cartridge because extra labels can cause the cartridge to jam in a tape drive.
Guidelines for bar code labels
Apply the following guidelines whenever bar code labels are used. · Do not reuse a label or reapply a used label over an existing label. · Before you apply a new label, remove the old label by slowly pulling it at a right angle to the cartridge
case. · Use peel-clean labels that do not leave a residue after it is removed. If glue residue is on the cartridge,
remove it by gently rubbing it with your finger. Do not use a sharp object, water, or a chemical to clean the label area. · Examine the label before it is applied to the cartridge. Do not use the label if it has voids or smears in the printed characters or bar code. A library 's inventory operation takes much longer if the bar code label is not readable. · Remove the label from the label sheet carefully. Do not stretch the label or cause the edges to curl. · Position the label within the recessed label area (see 5 in Figure 85 on page 157). · With light finger pressure, smooth the label so that no wrinkles or bubbles exist on its surface. · Verify that the label is smooth and parallel, and has no roll-up or roll-over. The label must be flat to within 0.5 mm (0.02 in.) over the length of the label and have no folds, missing pieces, or smudges. · Do not place other machine-readable labels on other surfaces of the cartridge. They might interfere with the ability of the drive to load the cartridge.
Write-Protect switch
All rewriteable data cartridges have a write-protect switch to prevent accidental erasure or overwriting of data. Before a cartridge is loaded into the device, make sure the write-protect switch on the front of the cartridge is in the wanted position.
162 Dell EMC ML3 Tape Library: User's Guide

The position of the write-protect switch on the tape cartridge (see 1 ) determines whether you can write to the tape. If the switch is set to:
· Slide the switch to the right to write-protect the cartridge. An indicator, such as a red mark or small
padlock, is visible showing that the cartridge is write-protected. · Slide the switch to the left to allow the device to write data to the cartridge.
If possible, use your server's application Software to write-protect your cartridges (rather than manually setting the write-protect switch). This setting allows the server's Software to identify a cartridge that no longer contains current data and is eligible to become a scratch (blank) data cartridge. Do not writeprotect scratch (blank) cartridges; the tape drive is not able to write new data to them.
If you must manually set the write-protect switch, slide it left or right to the wanted position.

Handling the cartridges
Attention: Do not insert a damaged tape cartridge into the drive. A damaged cartridge can interfere with the reliability of a drive and might void the warranties of the drive and the cartridge. Before a tape cartridge is inserted, inspect the cartridge case, cartridge door, and write-protect switch for breaks.
Incorrect handling or an incorrect environment can damage cartridges or their magnetic tape. To avoid damage to your tape cartridges and to ensure the continued high reliability of your LTO Ultrium Tape Drives, use the following guidelines.
Providing training
· Post procedures that describe appropriate media handling in places where people gather. · Ensure that anyone who handles tape is properly trained in handling and shipping procedures. This
training includes operators, users, programmers, archival services, and shipping personnel. · Ensure that any service or contract personnel who complete archiving procedures are properly trained
in media-handling procedures. · Include media-handling procedures as part of any services contract. · Define and make personnel aware of data recovery procedures.

Appendix C. LTO media 163

Ensuring proper packaging
· When a cartridge is shipped, use the original or better packaging. · Always ship or store a cartridge in a jewel case. · Use only a recommended shipping container that securely holds the cartridge in its jewel case during
transportation. · Never ship a cartridge in a commercial shipping envelope. Always place it in a box or package. · If you ship the cartridge in a cardboard box or a box of a sturdy material, ensure that you
­ Place the cartridge in polyethylene plastic wrap or bags to protect it from dust, moisture, and other contaminants.
­ Pack the cartridge snugly; do not allow it to move around. ­ Double-box the cartridge (place it inside a box, then place that box inside the shipping box) and add
padding between the two boxes (see Figure 89 on page 164).
Figure 89. Double-boxing tape cartridges for shipping
Proper acclimation and environmental conditions
To ensure the longest possible life for your data cartridges, follow these guidelines. · Before you use a tape cartridge, acclimate it to the operating environment for 24 hours or the time
necessary to prevent condensation in the drive. The time varies, depending on the environmental extremes to which the cartridge was exposed. If the data cartridge was exposed to temperatures outside the specified ranges, stabilize the cartridge at room temperature for the same length of time it was exposed to extreme temperatures or 24 hours, whichever is less. · Ensure that all surfaces of a cartridge are dry before it is inserted. · Do not expose data cartridges to direct sunlight or sources of heat, including portable heaters and heating ducts. · Do not place data cartridges near sources of electromagnetic energy or strong magnetic fields such as computer monitors, electric motors, speakers, or X-ray equipment. Exposure to electromagnetic energy or magnetic fields can destroy data and the embedded servo code that is written on the media by the cartridge manufacturer, which can render the cartridge unusable. · Use only the data cartridges that are designated for your device. · Clean the tape drive when the Clean drive LED is illuminated. · Do not drop a cartridge. Excessive shock can damage the internal contents of the cartridge or the cartridge case itself, making the cartridge unusable. · Place identification labels only in the designated area on the cartridge.
164 Dell EMC ML3 Tape Library: User's Guide

· Maintain the conditions that are described in "Environmental and shipping specifications for tape cartridges" on page 166. Attention: Do not degauss LTO data cartridges! These data cartridges are pre-recorded with a magnetic servo signal. This signal is required to use the cartridge with the LTO tape drive. Keep magnetically charged objects away from the cartridge.
Completing a thorough inspection
After a cartridge is purchased and before it is used, complete the following steps. · Inspect the cartridge's packaging to determine potential rough handling. · When a cartridge is inspected, open only the cartridge door. Do not open any other part of the cartridge
case. The upper and lower parts of the case are held together with screws; separating them impairs the usefulness of the cartridge. · Inspect the cartridge for damage before it is used or stored. · Inspect the rear of the cartridge (the part that loads first into the tape load compartment) and ensure that no gaps appear in the seam of the cartridge case. . If gaps appear in the seam (see Figure 90 on page 165), the leader pin might be dislodged.
Figure 90. Checking for gaps in the seams of a cartridge · Check that the leader pin is properly seated. . · If you suspect that the cartridge was mishandled but it appears usable, copy any data onto a good
cartridge immediately for possible data recovery. Discard the mishandled cartridge. · Review handling and shipping procedures.
Handling the cartridge carefully
· Do not drop the cartridge. If the cartridge drops, slide the cartridge door back and ensure that the leader pin is properly seated in the pin-retaining spring clips..
· Do not handle tape that is outside the cartridge. Handling the tape can damage the tape's surface or edges, which might interfere with read or write reliability. Pulling on tape that is outside the cartridge can damage the tape and the brake mechanism in the cartridge.
· Do not stack more than six cartridges. · Do not degauss a cartridge that you intend to reuse. Degaussing makes the tape unusable.
Appendix C. LTO media 165

Environmental and shipping specifications for tape cartridges

Before you use a tape cartridge, acclimate it to the operating environment for 24 hours or the time necessary to prevent condensation in the drive. The time varies, depending on the environmental extremes to which the cartridge was exposed. If the data cartridge was exposed to temperatures outside the specified ranges, stabilize the cartridge at room temperature for the same length of time it was exposed to extreme temperatures or 24 hours, whichever is less.
The best storage container for the cartridges (until they are opened) is the original shipping container. The plastic wrapping prevents dirt from accumulating on the cartridges and partially protects them from humidity changes.
When you ship a cartridge, place it in its jewel case or in a sealed, moisture-proof bag to protect it from moisture, contaminants, and physical damage. Ship the cartridge in a shipping container that has enough packing material to cushion the cartridge and prevent it from moving within the container.
Table 51 on page 166 gives the environment for operating, storing, and shipping LTO Ultrium Tape Cartridges.

· Fast/Wide SCSI - Uses a 16-bit bus, and supports data rates of up to 20 MBps.
· SCSI-1 - Uses an 8-bit bus, and supports data rates of 4 MBps.
· SCSI-2 - Same as SCSI-1, but uses a 50-pin connector instead of a 25-pin connector, and supports multiple devices.
· Ultra-SCSI - Uses an 8- or 16-bit bus, and supports data rates of 20 or 40 MBps.
· Ultra2 SCSI - Uses an 8- or 16-bit bus and supports data rates of 40 or 80 MBps.
· Ultra3 SCSI - Uses a 16-bit bus and supports data rates of 80 or 160 MBps.
· Ultra160 SCSI - Uses a 16-bit bus and supports data rates of 80 or 160 MBps.
· Ultra320 SCSI - Uses a 16-bit bus and supports data rates of 320 MBps.
