3. Set the mapped external volume as the source volume and local storage system internal volume
as the target volume.
4. Migrate the existing data in the mapped external volume to the local storage system internal
volume manually using XP Auto LUN.

The mapped external volume is set as the S-VOL of the XP Continuous Access pair, and the volume
in the local storage system that is connected as the multipoint control unit (MCU) is set as the P-VOL
of the XP Continuous Access pair. For details on XP Continuous Access, see the HP StorageWorks
XP24000/XP20000 Continuous Access Software User Guide.
The procedure for the operation is as follows:
1. Use XP External Storage to map a volume in the external storage system as an internal volume
of the local storage system, which is used as remote control unit (RCU) for the XP Continuous
Access operation.
You can select the emulation type of the mapped volume as you required. If you select the
emulation type for the open system (such as OPEN-V), go to step 2. If you select the emulation
type for the mainframe system (such as 3390-3), go to step 3.
For details on the mapping operation, see
(page 63).
2. If you set the emulation type for the open system when you map the volume, the status of the
mapped volume automatically becomes Normal. However, the volume formatting processing
is not executed automatically. If you need to format the mapped volume, format the volume
using the VLL function.
For the volume formatting operation procedure, see the HP StorageWorks XP24000/XP20000
Virtual LVI/LUN (VLL) and Volume Shredder User Guide.
Go to step 4.
3. If you set the emulation type for the mainframe system when you map the volume, the status
of the mapped volume becomes Blockade. Format the volume using the VLL function. Or if
you have mapped the volume for which the data area has already been zero-formatted on
