Examples of using external volumes with other products

For the following P9500 program products, the examples of using external volumes are described
in the following sections:

“Auto LUN operations ” (page 13)

“Continuous Access Synchronous operations” (page 14)

“Continuous Access Journal operations” (page 15)

“Business Copy operations” (page 16)

“Snapshot operations” (page 17)

Auto LUN operations

Figure 3 (page 14)

shows the use of an external volume for the Auto LUN operation. The mapped

external volume is set as the source volume and the local internal volume is set as the target volume.
Existing data in the external volume is migrated manually to the local storage system internal volume
using Auto LUN. For more information on Auto LUN, contact HP Technical Support (see

“Support

and other resources” (page 66)

).

The procedure for the operation is as follows:
1.

Use External Storage to map a volume in the external storage system as an internal volume
of the local storage system.

For the case shown in

Figure 3 (page 14)

, set the attributes of the mapped volume as follows:

Emulation type: OPEN-V

CAUTION:

To migrate the existing data in the mapped external volume to the local storage system
volume using Auto LUN, set the emulation type to OPEN-V as you map the volume. The
emulation type must be OPEN-V to read out the existing data in the external volume from
the local storage system side.

To copy the existing data in the mapped external volume using the copy program products
of Remote Web Console such as Continuous Access Synchronous and 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 required using the LUSE function and the Virtual
LVI/Virtual LUN function. See the HP P9000 Provisioning for Open Systems User Guide and
the HP P9000 Provisioning for Mainframe Systems User Guide.

CAUTION:

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 Auto LUN.
