iSCSI Target Login Failure After Restore

In some cases a restore will succeed, but a subsequent login to an iSCSI target will fail with a "Missing Disk" error in Diskshadow.

In a single-node scenario, ensure the connection manager is installed. Then connect the LUN to the host.
In a cluster scenario, where a restore is done on only one of the nodes belonging to a cluster, you must connect the LUNs to all the hosts involved in the cluster after the restore has completed. Be sure you place the volume or resource from the cluster in the offline state, then perform the restore. After the restore has completed, add the resource back to the cluster.
