Example of Continuous Access XP Journal operations

1. Use External Storage XP to map the volume in the external array as an internal LDEV of the local array,
which is used as the RCU for Continuous Access XP Journal operations.
CAUTION:
Select the mapped volume's emulation type as required. If you select an open-system emulation type
(such as OPEN-V), go to
to step 3.
For more information, see
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
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. 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
