Figure 14 Example of Auto LUN XP operations
1. Use External Storage XP to map a volume in the external array to an internal LDEV of the local
array.
For this example, 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:
To migrate existing data in the mapped external LU to a local array volume using Auto LUN
XP or Business Copy XP, as shown in
Figure 14 , set the local array's emulation type to
OPEN-V when mapping the LU. Only OPEN-V emulation can be used to read existing data
in the external LU from the local array side.
To copy existing data in the mapped external LU using HP StorageWorks software products,
such as Continuous Access XP and Business Copy XP, the mapped external LU's emulation
type must also be OPEN-V.
2. Prepare a local array internal LDEV with the same capacity as the mapped external LU. Use
Volume Manager to adjust the internal LDEV's capacity as required. For instructions, see the
HP StorageWorks LUN Configuration and Security Manager XP user guide for the
XP12000/XP10000/SVS200.
CAUTION:
The emulation type of the local array's prepared internal LDEV must be OPEN-V.
3. Set the mapped external LU as the source volume, and set the local array internal LDEV as the
target volume.
4. Use Auto LUN XP to manually migrate existing data in the mapped external LU to the local array
internal LDEV (without changing the associated LDEV/LU).
