Modify a Snapshot

You can modify a snapshot in the following ways: edit, delete, set online, or set offline. You can clone or restore a volume from a selected snapshot.

When snapshots are created, they are set offline. Setting a snapshot offline makes it unavailable to initiators, and closes any current connections.
