HP StorageWorks External Storage XP user guide for the XP12000, XP10000, SVS200 (T1706-96009, October 2007)

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-VwhenmappingtheLU.OnlyOPEN-Vemulationcanbeusedtoreadexistingdata
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 mapp
ed 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).
Using external LUs for Continuous Access XP operations
Figure 15 shows an example of using an external LU for Continuous Access XP operations. The mapped
external LU is set as the Continuous Access XP pair's S-VOL, and the volume in the local array that is
connected as the MCU is set as the Continuous Access XP pair's P-VOL. For more information about
Continuous Access XP operations, see the HP StorageWorks Continuous Access XP user guide for the
XP12000/XP10000/SVS200.
