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 LUN Configuration and Security Manager XP user
guide for the XP12000/XP10000/SVS200.
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 LUN Configuration and Security Manager XP user guide for the
XP12000/XP10000/SVS200.
Go to step 4.
4. Set the Business Copy XP pair's P-VOL and S-VOL.

Using external LUs for Snapshot XP operations

Figure 18 shows an example of using an external LU for Snapshot XP operations. The mapped external
LU is set as a pool-VOL for the Snapshot XP pair.
For more information about Snapshot XP, see the HP StorageWorks Snapshot XP user guide.

Use External Storage XP 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 a Snapshot XP pool-VOL. Set the
IO Suppression mode to Disable.
