To copy the existing data in the mapped external volume using the copy program products
of Remote Web Console such as XP Continuous Access and XP Business Copy, the emulation
type of the mapped external volume also has to be OPEN-V.
2.
Prepare the local internal volume that has the same capacity as the mapped external volume.
Adjust the capacity of the internal volume as it is required using the VLL function.
For the VLL function, see the HP StorageWorks XP24000/XP20000 Virtual LVI/LUN (VLL) and
Volume Shredder User Guide.
The emulation type of the prepared internal volume must be OPEN-V.
3.
Set the mapped external volume as the source volume and local storage system internal volume
as the target volume.
4.
Migrate the existing data in the mapped external volume to the local storage system internal
volume manually using XP Auto LUN.
Figure 14 Example of the XP Auto LUN Operations
XP Continuous Access Operations
shows the use of an external volume for the XP Continuous Access operation.
The mapped external volume is set as the S-VOL of the XP Continuous Access pair, and the volume
in the local storage system that is connected as the multipoint control unit (MCU) is set as the P-VOL
of the XP Continuous Access pair. For details on XP Continuous Access, see the HP StorageWorks
XP24000/XP20000 Continuous Access Software User Guide.
The procedure for the operation is as follows:
1.
Use XP External Storage to map a volume in the external storage system as an internal volume
of the local storage system, which is used as remote control unit (RCU) for the XP Continuous
Access operation.
You can select the emulation type of the mapped volume as you required. If you select the
emulation type for the open system (such as OPEN-V), go to step 2. If you select the emulation
type for the mainframe system (such as 3390-3), go to step 3.
For details on the mapping operation, see
“Mapping an External Volume Automatically”
2.
If you set the emulation type for the open system when you map the volume, the status of the
mapped volume automatically becomes Normal. However, the volume formatting processing
