ERROR [Thread-1582 (HornetQ-client-global-threads-235452xxx)] [com.emc.archway.service.vcenter.VCenterServiceBean] [XXXXX] [] Exception Occurred: VCenterServiceOperationFailedException, Message: Virtual center service operation failed with error: Failed to mount any of the datastores. Using the VI client, check the ESX servers for tasks and events, or alarms.

Cause

If copy target LUNs are exposed to ESX, but they are not mounted (unmounted state) as datastores to ESX, then we may encounter this error.

Snaps of the datastore that are exposed to the ESX host but not mounted to the ESX host can be considered stale copies and can cause this error.

Resolution

Resolution:
Unmask all the snapshots of the device in array from esxi host; so that none of the snapshots mask the ESXi host and then delete it. Rescan the bus on the ESX host to ensure they are removed.

Additional Information

For AppSync 4.0 and VCenter 6.5, the error seen in the CSV events will be:
