2. Use XP External Storage to map the LU in the external array containing data as an internal LDEV
of the local array.
When mapping the external LU, set the following attributes for the mapped LU:
• Emulation type: OPEN-V
• IO Suppression mode: Disable
For more information, see Mapping external LUs (Add LU) .
CAUTION:
You must set the emulation type to OPEN-V to read existing data in the mapped external
LU from the local array side.
3. Configure the path from the Target port to the mapped LU to perform host I/O operations.
After the path is set, host I/O operations to the mapped volume are available.
NOTE:
Do not access any external storage volume that is mapped as an XP External Storage volume from a
host connected directly to the external array. Also, do not access an XP External Storage mapped
external array volume using the external array's functions (for example, local replication). After
mapping an external disk volume as a local array volume, access the mapped external disk volume
only via the local array.
NOTE:
Except on the MSA, a host can directly access external array volumes that are not mapped as local
array volumes.
