IntelliSnap - Troubleshooting

You have a restore failure performing an application aware revert or performing a hardware specific revert.

Before performing a revert operation:

RevertSnapVolume has been set to 1
Make sure the archived redo log files and their mirror log files reside on the same array volume
All the databases on a volume must be backed up using IntelliSnap backup, failing of which will make the data inconsistent
All the databases on a volume must be selected for the revert operation. Also, the databases must be backed up using a single IntelliSnap backup job
Ensure that the Unconditionally Overwrite restore option is selected for SQL Server iDataAgent. If this option is not selected, restores of IntelliSnap backup data will fail
On Windows clients, disable automount using the following command:
```
diskpart> automount disable
```

Now, follow these steps,

Set the cluster resource disk maintenance mode to be ON with the command:
```
cluster res "cluster disk #" /maint:on
```
Revert

After performing the revert operation, you must restart the SQL Server service so that the databases are re-linked to the data files
Set the cluster resource disk maintenance mode to be OFF with the command:
```
cluster res "cluster disk #" /maint:off
```

Restoring cluster snap backup to the source failed.

Set the cluster resource disk maintenance mode to be ON with the command:
```
cluster res "cluster disk #" /maint:on
```
Restore
Set the cluster resource disk maintenance mode to be OFF with the command:
```
cluster res "cluster disk #" /maint:off
```

Mounting snapshots to a cluster disk destination failed.

Set the cluster resource disk maintenance mode to be ON with the command:
```
cluster res "cluster disk #" /maint:on
```
Mount
Set the cluster resource disk maintenance mode to be OFF with the command:
```
cluster res "cluster disk #" /maint:off
```

Backup operation skips to protect Always On Databases that are a part of an instance in a cluster.
