Initializing th

e Pool Management Block

If you initializ

e the pool management block, I/O performance of the pool will improve compared to

before initial

ization. You can initialize the pool management block without changing the pools already

created in the storage system.

The procedure for initializing the pool management block is the same as the proce-

dure for initializing the V-VOL management area. Therefore, see the procedure in

“Initializing V-VOL Management Area” on page 57 to initialize the pool management block.

Note:

You may n

eed up to 20 minutes to initialize the pool management block.

This section describes how to create new V-VOLs. In addition, the procedures for deleting pools are

also described in this section.

Creating New Virtual Volumes

To create new

virtual volumes:

1. Change the mode of the Remote Web Console to Modify.

If the mode is already changed to Modify, you can skip this step. For information on to change

the mode, see the HP StorageWorks XP24000 Remote Web Console User’s Guide.

2. Right-click XP Snapshot in the V-VOL group tree of the V-VOL dialog box.

4. Select or en

ter the V-VOL group ID in the V-VOL Group drop-down list.

Note:

You ca

n enter only a whole number from 1 to 65536. Do not enter a number that is

already used for another V-VOL group.

5. Select the emulation type of the V-VOL group from the Emulation Type drop-down list.

6. Select the CLPR number of the CLPR in which you want to register the V-VOL group from the

However,

when the external volume groups of External Storage or the V-VOL groups of XP

Thin Pro

visioning are created, the available V-VOL groups for XP Snapshot will be fewer than

the maxi

mum number according to the number of the external volume groups and V-VOL

groups

of XP Thin Provisioning. For example, if 10 external volume groups are created for

External Storage, you can enter only a whole number under 63221.

• If you create multiple V-VOL groups at a time, all V-VOLs that are going to be registered in

each V-

VOL group will have the same emulation type and capacity.

8. Click Next.

The Create V-VOL wizard dialog box (1) (Figure 16 on page 61) is displayed.

9. Select the emulation type of the V-VOL from the Emulation Type drop-down list.

unit is blocks, enter a whole number from 96000 to 4294967296. If the unit is cylinders,
