Dell Avamar Platform OS Security Patch Rollup 2023R3 Release Notes

Quick guide from the manual

This document provides release notes and instructions for the Dell Avamar Platform OS Security Patch Rollup 2023R3. It covers the necessary steps to apply security and operating system updates, specifically focusing on managing disk space on the /boot volume for Avamar Data Store (ADS) systems.

Avamar platform OS security patch rollup

The rollup automates security and OS updates for various Avamar products, including Avamar server, Avamar combined proxy, Avamar Virtual Edition (AVE), Avamar Data Store (ADS), Avamar NDMP accelerator node, NetWorker Virtual Edition (NVE), and PowerProtect DP Series Appliance.

Cleaning /boot volume

If you are applying the OS security patch rollup on ADS, you may need to free up space on the /boot volume.

Prerequisites

• For multi-node servers, perform this procedure on the utility node, all storage nodes, spare nodes, and accelerator nodes.
• When applying the Security Rollup manually, the required free space on the /boot volume is 80MB.

Procedure

1. Log in to the server (single-node) or utility node (multi-node) as admin and switch to root using su -.
2. Check space: df -h /boot/.
3. Check for kdump files: ls -l /boot/*kdump.
4. Remove kdump files: rm /boot/*kdump.
5. List kernels: rpm -qa |grep kernel-default.
6. Remove old kernels: rpm -ev kernel-default-VERSION_OLD kernel-default-base-VERSION_OLD.
7. Check for archived .gz files: ls -l /boot/*.gz.
8. Remove archived files: rm /boot/*.gz.
9. If space is still insufficient (less than 80MB), back up the running kernel to /usr/local/avamar/var/rollup_bak before proceeding.
10. Restore the running kernel after installation using mv /usr/local/avamar/var/rollup_bak/*-default /boot.
