Managing Pools
This section describes the procedures to manage the pool:
• Creating pools
• Changing the pool settings
• Deleting pools
• Recovering pools
Creating Pools
The required time for creating pools depends on the number and the capacity of the pools and pool-VOLs
that you add to the pool. If you create many pools or if you add a pool-VOL of large capacity, it may
take up to 20 minutes until the entire processing ends.
To create a new pool:
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 how to
change the mode, see the HP StorageWorks XP24000 Remote Web Console User’s Guide.
2. Right-click XP Thin Provisioning in the Pool tree of the Pool window ( Figure 6 on page 33).
A pop-up menu is displayed.
3. Select New Pool from the pop-up menu.
The New Pool dialog box ( Figure 11 on page 45) is displayed.
4. Enter the pool ID in the Pool ID text box.
Note: You can enter only a whole number from 0 to 127 in this text box. Do not enter any
number that is already used for another pool.
5. Select the threshold of the pool usage rate from the Threshold drop-down list.
6. Select XP Thin Provisioning from the Attribute drop-down list.
7. Check the contents of the setting, and if there is no problem, click Set.
The New Pool dialog box closes, and the new pool will be displayed in the Pool tree.
8. Select the pool in the Pool tree.
9. Select the volumes that you want to register in the pool as the pool-VOLs from the Free LDEVs list.
Note:
• If you select the CU number from the CU drop-down list, the volumes in the CU will be
displayed in the list. Within the same CU, you can select multiple volumes at a time.
• If you select an LDKC number from the drop-down list, only the CU of the LDKC will be
displayed in the CU drop-down list.
10. Click Add Pool-VOL.
The dialog box that lists the volumes you selected in step 9 is displayed.
Note: If you select and right-click the volume in the Free LDEVs list, a pop-up menu will be
displayed. If you select Add Pool-VOL from the pop-up menu, the result will be the same
as when you click Add Pool-VOL.
11. Check the list of the volumes and if there is no problem, click OK.
The dialog box closes and the selected volumes will be displayed in the Pool-VOL list.
12. To add more pool-VOLs, repeat step 9 and the subsequent steps.
Note:
• The total capacity of the pool-VOLs in the pool is the storage capacity of the pool.
• The capacity of the pool management blocks in use will increase if you add pool-VOLs. You
need to be careful to keep the capacity of the pool management blocks in use less than its
total capacity.
13. To create another pool, repeat step 2 and the subsequent steps.
