The snap restore_volume command restores a storage system volume from the specified Snapshot copy.
sdcli snap restore_volume [-f StorageSystemName] -volume StorageSystemVolumeName -s SnapshotCopyName [-force] [-m MachineName]
-f StorageSystemName is the name of the storage system on which the volume resides.
-volume StorageSystemVolumeName indicates name of the volume on which the restore operation will be performed.
-s SnapshotCopyName indicates the name of the Snapshot copy from which the volume will be restored.
-force is an optional switch that you use to ensure the volume restoration is performed even when non-LUN files or newer Snapshot copies are found on the volume.
