1. Use XP External Storage to map a volume in the external array to an internal LDEV of the local
array.
CAUTION:
You must set the volume's emulation type to OPEN-V when mapping the volume. You can
set only a volume with the OPEN-V emulation type as an XP Snapshot pool-VOL. Set the
IO Suppression mode to Disable.
For more information, see Mapping external LUs (Add LU) .
2. The mapped volume's status automatically becomes Normal. However, the volume formatting
processing does not execute automatically. To format the mapped volume, format the volume
using the CVS function. For instructions, see the HP StorageWorks XP LUN Configuration and
Security Manager user guide: HP XP12000 Disk Array, HP XP10000 Disk Array, HP 200 Storage
Virtualization System.
3. Create a pool, and add the mapped external LU to that pool as a pool-VOL.
4. Set the XP Snapshot pair's P-VOL and S-VOL specifying the pool you created in step 3.
