We are running SMSQL version 5.1 and I am trying to run a normal daily backup of one of my SQL servers. I am running exactly the same scripts etc on all my other servers with success but this one is causing me massive problems.
As you can see from the extract below the backup is failing to mount the snapshot. Does anybody have any idea why this is happening? I have tried all manner of things to try to resolve this but all has been futile.
For example I have checked the C:\Program Files\NetApp\SnapManager for SQL Server\SnapMgrMountPoint to see if there was a 'stuck' mount point which there wasn't. I also stopped and restarted the SnapDrive & SnapManager services which sometimes resolves minor issues. This didn't. I then re-ran the Configuration Wizard which also proved futile.
