The snap rename command enables you to change the name of an existing Snapshot copy.
sdcli snap rename [-m MachineName] -d MountPoint -o OldSnapshotName -n NewSnapshotName
sdcli snap rename -d j -o Jun_13_03 -n last_known_good
The preceding example changes the name of the June_13_03 Snapshot copy associated with the J: drive to last_known_good.
