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
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 (page 44) 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.
For more information about XP Snapshot, see the HP Snapshot XP user guide for XP12000/XP10000
Disk Arrays and SVS 200.
Figure 18 Example of XP Snapshot operations
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 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.
