On-host agent may be unavailable after restore with a snapshot taken with NetBackup CloudPoint 8.3
After a restore that uses a snapshot that was taken with NetBackup CloudPoint 8.3, the on-host agent may not be available.
The on-host agent is unable to connect to rabbitmq after a CloudPoint upgrade and continues to fail for some time. The jobs that are triggered while the agent is not connect to rabbitmq fail with error:
Agent agent.203f5661cdd0448bbb63138b5000e0c7 is offline on the host azure-vm-a3d6ef3b-e12f-4754-ba75-84084c1d693c.
During the upgrade, the on-host agent from an actual VM "auto-grt-97230" released the earlier connection, and the agent on the restored VM was able to connect on the same queue. After the upgrade, the source on-host agent did not get the lock and then continued to fail with the resource_locked error, making the on-host agent offline.
Workaround:
Follow these steps if you want to take the application-consistent snapshots of the restored instance:
On the restored host:
For a Linux on-host agent, follow the steps from the Veritas NetBackup CloudPoint Install and Upgrade Guide section Registering the Linux-based agent.
For a Windows on-host agent, follow the steps from the Veritas NetBackup CloudPoint Install and Upgrade Guide section Registering the Windows-based agent.
Note:
Ensure that you have removed the previously installed on-host agent before installation and re-registration.
