2.
Prepare a local array internal LDEV with the same capacity as the mapped external LU. Use
Volume Manager to adjust the internal LDEV's capacity as required. For instructions, see the
HP XP LUN Configuration and Security Manager user guide: HP XP12000 Disk Array, HP
XP10000 Disk Array, HP 200 Storage Virtualization System.
CAUTION:
The emulation type of the local array's prepared internal LDEV must be OPEN-V.
3.
Set the mapped external LU as the source volume, and set the local array internal LDEV as
the target volume.
4.
Use XP Auto LUN to manually migrate existing data in the mapped external LU to the local
array internal LDEV (without changing the associated LDEV/LU).
Using external LUs for XP Continuous Access operations
shows an example of using an external LU for XP Continuous Access operations.
The mapped external LU is set as the XP Continuous Access pair's S-VOL, and the volume in the
local array that is connected as the MCU is set as the XP Continuous Access pair's P-VOL. For more
information about XP Continuous Access operations, see the HP XP Continuous Access user guide
for XP12000/XP10000 Disk Arrays and SVS 200.

1.
Use XP External Storage to map a volume in the external array to an internal LDEV of the local
XP Continuous Access RCU array.
CAUTION:
Set the IO Suppression mode to Disable.
Select the mapped volume's emulation type as required. If you select an open-system emulation
type (such as OPEN-V), go to step 2. If you select a mainframe-system emulation type (such
as 3390-3), go to step 3.
For more information, see
2.
If you set an open-system emulation type when mapping the volume, the mapped volume's
status automatically becomes Normal. However, the volume-formatting process is not
automatically executed. To optionally format the mapped volume, use the Custom Volume
Size (CVS) function. For instructions, see the HP XP LUN Configuration and Security Manager
