Patch Name And Size

• Size: We increased the size of the patch SWU files. The files may take a longer time to download. Also, follow the instructions in the Check the Available Disk Space section to confirm you have enough available disk space with the new file sizes.

Patch Description

This patch, update-fcsf-ROLLUP20251106-7.5.3-v2-01.swu, includes security fixes.

Previous fixes included in this patch are described in Previous Fixes.

Before You Begin

Make sure you have enough available space on the Manager for all appliance SWU files that you upload to Update Manager. Also, confirm you have enough available space on each individual appliance.

Check the Available Disk Space

Use these instructions to confirm you have enough available disk space:

1. Log in to the Appliance Admin interface.
2. Click Home.
3. Locate the Disk Usage section.
4. Review the Available (byte) column and confirm that you have the required disk space available on the /Lan cope/var/ partition.

• Requirement: On each managed appliance, you need at least four times the size of the individual software update file (SWU) available. On the Manager, you need at least four times the size of all appliance SWU files that you upload to Update Manager.
• Managed Appliances: For example, if the Flow Collector SWU file is 6 GB, you need at least 24 GB available on the Flow Collector (/Lan cope/var) partition (1 SWU file x 6 GB x 4 = 24 GB available).
• Manager: For example, if you upload four SWU files to the Manager that are each 6 GB, you need at least 96 GB available on the /Lan cope/var partition (4 SWU files x 6 GB x 4 = 96 GB available).

The following table lists the new patch file size:

Appliance	Patch File Size
Manager	6.07 GB
