Abstract
A clustered storage array consists of several nodes coupled to one or more storage systems. The nodes provide a LUN-device for access by a client, the LUN-device mapping to a source logical unit corresponding to areas of storage on the one or more storage systems. A target logical unit corresponds to different areas of storage on the one or more storage systems. The source logical unit is migrated in parallel by the several nodes to the target logical unit.
