1. Use XP External Storage to map a volume in the external array to an internal LDEV of the local
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 Mapping external LUs (Add LU) .
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 StorageWorks XP LUN Configuration and Security Manager user
guide: HP XP12000 Disk Array, HP XP10000 Disk Array, HP 200 Storage Virtualization Systemr.
Go to step 4.
3. If you set a mainframe-system emulation type when mapping the volume, the mapped volume's
status becomes Blockade. To format the volume, use the CVS function. To restore the volume,
perform the Write to Control Blocks operation if you mapped a volume for which the data area
has already been zero-formatted on the external array side. 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.
Go to step 4.
4. Set the XP Business Copy pair's P-VOL and S-VOL.
Using external LUs for XP Snapshot Software operations
Figure 18 shows an example of using an external LU for XP Snapshot operations. The mapped external
LU is set as a pool-VOL for the XP Snapshot pair.
