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.
For zero-formatted external volumes, when you select that volume to map, you can use the
Virtual LVI function to perform the Write to Control Blocks operation to restore the volume. For
instructions on how to format volumes and the Write to Control Blocks operation, see the HP
P9000 Provisioning for Mainframe Systems User Guide.
Go to step 4.
4. To perform the host I/O operations, set the LU path from the Target port to the mapped volume.
After the LU path is set, the host I/O operation to the mapped volume becomes available.
Figure 22 (page 59) illustrates storing the new data in the mapped external volume.

Using existing data in the mapped external volume
To use the existing data in the mapped external volume from the host that is connected to the local
storage system:
1.
Store the data from the host that is connected to the external storage system to the volume in
the external storage system.
2. Map the volume containing data in the external storage system as an internal volume of the
local storage system using External Storage.
When you map the external volume, set the attributes of the mapped volume to Emulation
type = OPEN-V to read the existing data in the mapped external volume from the local storage
system side.
3. Set the LU path from the Target port to the mapped volume to perform the host I/O operation.
After the LU path is set, the host I/O operation to the mapped volume can be initiated.
