2. For open-system emulation types (such as OPEN-V, which HP recommends), the status of the
mapped LDEV is set to Normal and is not automatically formatted. To optimally initialize the
mapped LU's data area, use Volume Manager to format the mapped LU. For instructions, see
the HP StorageWorks XP LUN Configuration and Security Manager user guide: HP XP12000
Disk Array, HP XP10000 Disk Array, HP 200 Storage Virtualization System.
Go to step 4.
3. For mainframe-system emulation types (for example, 3390-XX), the status of the mapped LU is
set to Blockade, pending resizing and formatting. Use Volume Manager to format the volume. If
you mapped a volume for which the data area is already zero-formatted on the external array
side, use Volume Manager's Write to Control Blocks operation to restore the volume. For
instructions, see the HP StorageWorks XP LUN Configuration and Security Manager user guide:
HP XP12000 Disk Array, HP XP10000 Disk Array, HP 200 Storage Virtualization System.
4. Configure the path from the Target port to the mapped volume to perform host I/O operations.
The mapped LDEV is available for host I/O operations.
After the path is set, host I/O operations to the mapped LU are available.

Using existing data in mapped external LUs
Figure 10 shows an example of using existing data in a mapped external LU from the host connected
to the local array.
1. From the host connected to the external array, write data to the LU in the external array.
