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.

Figure 16

on page 39 shows the use of an external volume for the Continuous Access Journal operation.

In

Figure 16

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.
