volume belongs, in the format CLPR number:CLPRname. For more information about CLPRs, see the
HP StorageWorks XP Disk/Cache Partition user guide.
• Owner: Program that reserved the volume. If Auto LUN XP reserved this volume, USP is displayed. If

Reserving target volumes
To migrate volumes, you must reserve logical volumes as migration destinations (targets) regardless of the
migration method (manual or automatic). Migration will not take place if no logical volume is reserved.
NOTE: The term reserved volume refers to a volume that is reserved for use as a migration destination.
Reserved volumes are denoted by blue icons. The term normal volume sometime refers to a volume that
is not reserved as a migration destination.
