Figure 5 Example of the Continuous Access Journal operation
Business Copy operations
Figure 6 (page 17) shows the use of an external volume for the Business Copy operation. The
mapped external volume is set as the S-VOL of the Business Copy pair, and the local storage system
internal volume is set as the P-VOL of the Business Copy pair. For details on Business Copy, see
the HP P9000 Business Copy User Guide.
The procedure for the operation is as follows:
1.
Use External Storage to map a volume in the external storage system as an internal volume
of the local storage system.
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.
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 Virtual LUN function.
For the volume formatting operation procedure, see the HP P9000 Provisioning for Open
Systems User 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 Virtual LVI 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
Virtual LVI function to restore the volume.
For the volume formatting operation procedure and the Write to Control Blocks operation
procedure, see the HP P9000 Provisioning for Mainframe Systems User Guide.
Go to step 4.
4. Set the P-VOL and S-VOL of the Business Copy pair.
