Note:

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

emulationtypemustbe OPEN-V to read out the existing data in the external volume from the

local storage system side.

Caution:

To copy the existing data in the mapped external volume using the copy program

products of Remote Web Console such as Continuous Access 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 it is required using the LUSE function and VLL

function.

For the LUSE function, see the HP StorageWorks XP24000 LUN Expansion User’s Guide.For the

VLL function, see the HP StorageWorks XP24000 Virtual LVI/LUN (VLL) and Volume Shredder

User’s Guide.

Note:

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.

Figure 14 Example of the Auto LUN Operation

Continuous Access Operations

Figure 15 on page 37 shows the use of an external volume for the Continuous Access operation. In

Figure 15 on page 37, the mapped external volume is set as the S-VOL of the 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 Continuous Access pair. For details on Continuous Access, see the HP StorageWorks

XP24000 Continuous Access Software User and Reference Guide.

The p

rocedure for the operation is described as follows:

1. Use 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 Continuous Access

operation.

You c

an 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 forthe mainframesystem(such as 3390-3), gotostep3.
