HP XP External Storage Software - Manual (Page 38)

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.
4. Set the P-VOL and S-VOL of the Continuous Access Journal pair, as shown in
Figure 16 on page 39.
