HP StorageWorks External Storage XP user guide for the XP12000, XP10000, SVS200 (T1706-96009, October 2007)

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 s
et 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.
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 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.
