There are few conditions that affect the
snapdrive snap restore command's ability to restore a Snapshot copy.
Note: You should always take another Snapshot copy after you add a LUN to or remove a LUN from a disk group.
- If you add a host volume or file systems to a disk group after taking a Snapshot copy and then try to restore the Snapshot copy, you receive an error message. You must include the
force option (-f) on the command-line for the restore operation to succeed in this situation.
Note: Host volumes and file systems that you add after taking a Snapshot copy are no longer accessible when you create and restore the Snapshot copy.
- If you rename a host volume or a file system or change the mountpoint after taking a Snapshot copy and then try to restore it, the restore operation fails. You must include the
force option (-f) on the command-line for the restore operation to succeed in this situation.
Note: Use the
-f option with great care to make sure you do not accidentally overwrite something that you did not intend to overwrite.
- If you rename a LUN after taking a Snapshot copy and then try to restore that Snapshot copy, the restore operation fails. After you rename a LUN, you should take a new Snapshot copy.
Note: After you start a Snapshot restore operation, do not halt it. Halting this operation might leave the system in an inconsistent state. You might then need to perform a manual recovery.
