Mapping an External Volume Automatically
2.
If you set the emulation type for the open system when you map the volume, the status of the
mapped volume automatically becomes Normal. However, the volume formatting processing
is not executed automatically. If you need to format the mapped volume, format the volume
using the VLL function.
For the volume formatting operation procedure, see the HP StorageWorks XP24000 Virtual
LVI/LUN (VLL) and Volume Shredder User’s Guide.
Go to step 4.
3.
If you set the emulation type for the mainframe system when you map the volume, the status of
the mapped volume becomes Blockade. Format the volume using the VLL function. Or if you
have mapped the volume for which the data area has already been zero-formatted on the
external storage system side, perform the Write to Control Blocks operation using the VLL function
to restore the volume.
For the volume formatting operation procedure and the Write to Control Blocks operation
procedure, see the HP StorageWorks XP24000 Virtual LVI/LUN (VLL) and Volume Shredder
User’s Guide.
Go to step 4.

Set the P-VOL and S-VOL of the Continuous Access pair, as shown in
Figure 15 Example of the Continuous Access Operation
Continuous Access Journal Operations
on page 39 shows the use of an external volume for the Continuous Access Journal operation.
In
on page 39, the mapped external volume is set as the S-VOL of the Continuous Access
Journal pair, and the volume in the local storage system that is connected as the MCU is set as the
P-VOL of the Continuous Access Journal pair. For details on Continuous Access Journal, see the HP
StorageWorks XP24000 Continuous Access Journal Software User and Reference Guide.
The procedure for the operation is described as follows:
