Perform a Restore with Volumes in a Cluster

In case of application-aware restores such as SQL databases or exchange mailboxes, resources must be taken offline before any restore operations are performed.

You must have credentials that provide power user privileges or better.

You can perform a restore on a volume using a VSS provider. If you restart the VSS provider service while a snapshot is being taken, then the snapshot may fail. Therefore, perform the restore when there are no snapshots scheduled.

NOTE: The restore operation can only be performed on the source LUN.

From the list of local services on the Windows host, right click the VSS hardware Provider service and choose Stop.
Log out of the host.
Log into the host using Administrator privileges.
From the Start menu, type services to display the list of local services.
Double click the VSS hardware provider service to display the service properties.
Select the Log On tab.
From the Log On tab, change the user credentials to the logged in user credentials. Note that the credentials of the service must match the credentials of the Set-Configuration cmdlet you set in the next step.
Run the Set-Configuration powershell cmdlet using the Group Management IP address, and the array username and password.
Using the Failover Cluster UI, put the cluster-shared volume in maintenance mode.
Run resync on the node which owns the cluster resource.
The volume is automatically connected to the host, and the resource is up and running in the cluster. However, the volume is not yet connected to the other hosts in the cluster.
Log into the other hosts in the cluster and connect them to the volume using one of the following two methods:
- For iSCSI arrays, connect the volume to each host using connection manager.
- For Fibre Channel arrays, use Disk Management to do a rescan in each node to expose it and add it to the cluster.
Using the Failover Cluster UI, take the cluster-shared volume back out of maintenance mode.
