Application status of original instances may report errors for host-consistent restores to alternate locations
After restoring the host-consistent snapshot to an alternate location, the application status of the original instance that was connected using an on-host agent goes into an error state.
This issue occurs when the host-consistent snapshots that were taken on the instances with NetBackup 8.3 on-host agents are restored to an alternate location. It is recommended to follow the steps in the workaround after the restore for the host application-consistent snapshots completes.
The following error is an example of what is reported in the on-host agent logs in the source instance:
May 12 15:57:56 auto-grt-97230 flexsnap-agent-onhost[4604] MainThread pika.channel: WARNING - Received remote Channel.Close (405): "RESOURCE_LOCKED - cannot obtain exclusive access to locked queue 'flexsnap-agent.203f5661cdd0448bbb63138b5000e0c7' in vhost '/'.

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.
