1.

Use External Storage to map the volume in the external storage system as an internal volume of

the local storage system, which is used as RCU for the Continuous Access Journal operation.

You can select the emulation type of the mapped volume as you required. If you select the

emulation type for the open system (such as OPEN-V), go to step 2. If you select the emulation

type for the mainframe system (such as 3390-3), go to step 3.

For details on the mapping operation, see

Mapping an External Volume Automatically

” on page 69.

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 Journal pair, as shown in

Figure 16
