SQL snapshot or restore and granular restore operations fail if the Windows instance loses connectivity with the Snapshot Manager host
This issue occurs if the Snapshot Manager agent that is configured on a Windows instance loses network connectivity with the Snapshot Manager host. Snapshot Manager operations such as snapshot creation or restore for SQL Server and granular restore begin to fail for the Windows instance.
The connectivity failure may occur due to various reasons such as a services restart on the Snapshot Manager host as part of a Snapshot Manager software upgrade or a general network disruption.
The flexsnap-agent logs may contain messages similar to the following:
flexsnap-agent-onhost[2720] MainThread flexsnap.connectors.rabbitmq: ERROR - Unexpected exception() in main loop flexsnap-agent-onhost[2720] MainThread agent: ERROR - Agent failed unexpectedly
If Snapshot Manager is deployed in a Veritas NetBackup environment, the NetBackup logs may contain messages similar to the following:
Error nbcs (pid=5997) Failed to create snapshot for asset: <sqlassetname> Error nbcs (pid=5997) Operation failed. Agent is unavailable.
Workaround:
To resolve this issue, restart the Veritas Snapshot Manager Agent service on the Windows instance.
