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, seeMapping external LUs (Add LU)” on page 73.
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.
