How to prepare for an in-place OS upgrade on NetBackup servers

Description

This guide provides step-by-step instructions on how to prepare for the OS upgrade on NetBackup primary and media servers. It outlines the precautions that need to be taken to ensure a smooth transition without impacting the NetBackup environment.

Before upgrading the OS on NetBackup master and media servers, perform the following steps to ensure a successful OS upgrade:

1. Take a Catalog Backup:

   • This will ensure that all the backup data and configuration information is preserved.
   • Use the NetBackup Administration Console to initiate a hot catalog backup. 
   • Make sure to store the catalog backup in a secure location, preferably on a separate storage device.

2. Stop NetBackup Services:

   • Prior to the OS upgrade, it is recommended to stop all running operations and NetBackup services on the master and media servers.

3. Perform the OS Upgrade:

   • Follow the standard procedures provided by the OS vendor to upgrade the operating system on the master and media servers.
   • Ensure that you have the necessary OS installation media or upgrade files before starting the process.

4. Verify the OS Upgrade is complete and start the NetBackup services

   • Once the OS upgradation is complete, verify that the new OS version is installed correctly on the master and media servers.
   • Ensure that all the necessary drivers and updates are installed for the new OS version.
   • Bring up the NetBackup services and perform some test operations to make sure the program is running as expected.

5. Take Another Catalog Backup:

   • After the OS upgrade, take another backup of the NetBackup catalog to capture any changes or updates made during the OS upgrade process.
   • Use the same procedure mentioned in step 1 to initiate a full catalog backup using the NetBackup Administration Console.

By following these precautions, you can minimize the risk of any data loss or disruption to the NetBackup environment during the OS upgrade process.

Remember to consult the NetBackup documentation or contact Veritas support for any specific guidance related to your environment.
