mapped external volume is set as the source volume and the local internal volume is set as the
target volume. Existing data in the external volume is migrated manually to the local storage system
internal volume using XP Auto LUN. For detailed information on XP Auto LUN operations, see the
HP StorageWorks XP24000/XP20000 Auto LUN Software User Guide.

Emulation type: OPEN-V
To migrate the existing data in the mapped external volume to the local storage system volume
using XP Auto LUN, set the emulation type to OPEN-V as you map the volume. The emulation
type must be OPEN-V to read out the existing data in the external volume from the local storage
system side.
To copy the existing data in the mapped external volume using the copy program products
of Remote Web Console such as XP Continuous Access and XP Business Copy, the emulation
type of the mapped external volume also has to be OPEN-V.
2.
Prepare the local internal volume that has the same capacity as the mapped external volume.
Adjust the capacity of the internal volume as it is required using the VLL function.
For the VLL function, see the HP StorageWorks XP24000/XP20000 Virtual LVI/LUN (VLL) and
Volume Shredder User Guide.
The emulation type of the prepared internal volume must be OPEN-V.
