Figure 14 Example of XP Auto LUN operations
.
1. Use XP External Storage 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 XP Auto
LUN or XP Business Copy, 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 XP Continuous Access and XP Business Copy, 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 XP LUN Configuration and Security Manager user guide: HP XP12000 Disk Array,
HP XP10000 Disk Array, HP 200 Storage Virtualization System.
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 XP Auto LUN to manually migrate existing data in the mapped external LU to the local array
internal LDEV (without changing the associated LDEV/LU).
