Universal Replicator Operations
Figure 2-14 shows the use of an external volume for the Universal Replicator
operation. The mapped external volume is set as the S-VOL of the Universal
Replicator pair, and the volume in the local storage system that is connected
as the MCU is set as the P-VOL of the Universal Replicator pair. For details on
Universal Replicator, see the Universal Replicator User's Guide.
The procedure for the operation is as follows:
1. Use Universal Volume Manager 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 Universal Replicator 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
on to the step 2. If you select the emulation type for the mainframe system
(such as 3390-3), go on to the 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
VLL function.
For the volume formatting operation procedure, see the Virtual LVI/LUN
and Volume Shredder User's Guide.
Go on to the 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 Virtual LVI/LUN and Volume Shredder
User's Guide.
Go on to the step 4.
4. Set the P-VOL and S-VOL of the Universal Replicator pair.
