Using External Lus For Business Copy Xp Operations; Example Of Business Copy Operations - HP StorageWorks XP12000 User Manual

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, use
the Write to Control Blocks operation if you mapped the 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 Continuous Access XP Journal pair's P-VOL and S-VOL.

Using external LUs for Business Copy XP operations

Figure 17 shows an example of using an external LU for Business Copy XP operations. The mapped
external LU is set as the Business Copy XP pair's S-VOL, and the local array internal LDEV is set as
the Business Copy XP pair's P-VOL. For more information, see the HP StorageWorks Business Copy
XP user guide for the XP12000/XP10000/SVS200.
Figure 17 Example of Business Copy operations
1. Use External Storage XP 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.
