Upgrading NetBackup primary server in a non-clustered replicated configuration
In order for global failover to work correctly, both the main and the alternate site clusters must run the same version of NetBackup. This means that both clusters must be upgraded at the same time. The upgrade process requires the replication link to be disabled and each cluster to be upgraded independently.
To upgrade the NetBackup primary server in a non-clustered replicated configuration
- Suspend replication between the main and the alternate sites.
- Upgrade NetBackup on the main primary server by following the standard upgrade procedures. (Refer to the NetBackup Upgrade Guide.)
- Run backup and restore tests to confirm that the upgrade was successful.
- Ensure that the alternate primary server is isolated from the wider network so that it cannot contact the media servers and clients when it comes online.
- Bring the alternate primary server online and mount the replicated catalog volume to it.
- Upgrade NetBackup on the alternate site primary server following the standard upgrade procedures. (Refer to the NetBackup Upgrade Guide.)
- After the upgrade is complete take the alternate site primary server offline. Doing this action avoids unnecessary and potentially time consuming post processing operations on the alternate site catalog volume.
- Re-connect the alternate site primary server to the wider network.
- Restart the replication process and allow the replicated volume to fully synchronize.
