Combining Snapshot XP with Auto LUN XP

Regardless of the status of Auto LUN XP's migration plans (Auto LUN XP pairs), you cannot perform any

Snapshot operations on the volume the migration plan uses. To use a Snapshot XP P-VOL as the migration

plan's source volume, you must create the Snapshot XP pair first, and then create the migration plan.
When the Snapshot XP P-VOL and migration plan's source volume are shared, you can execute the

migration plan only when the Snapshot XP pair is in PAIR status. Deleting and canceling the migration

plan are always allowed. These operations are not affected by the Snapshot XP pair status.
For more information about the status of migration plans and Auto LUN XP operations, see the

HP StorageWorks Auto LUN XP user guide for the XP12000/XP10000.
