4. Click Apply. The confirmation message indicating if it is OK to apply the setting to the storage

system is displayed.

5. Click OK. The confirmation message closes and the restoration of the pools is applied to the

storage system.

6. You can check whether the pool is recovered from the blocked status in the Pool window. If

Status of the Pool Information displays Normal, or if the icon in the Pool tree indicates the

normal status, the blocked pool is restored successfully.

You can also recover the pool by doing one of the following operations:

• Add some pool-VOLs.

• Delete snapshot data to decrease the usage rate of the pool.

• Delete XP Snapshot pairs to decrease the usage rate of the pool.

The usage rate and status of the pool are displayed in the Pool Information box in the Pool window.

Use this information to decide how many pool volumes to add or which snapshot data to delete.

• Recovery of the XP Snapshot pair. When the pool is blocked, the status of all XP Snapshot

pairs that have snapshot data stored in the pool changes to PSUE. To recover the PSUE pairs,

delete those pairs.

• Recovery of the V-VOL. When the V-VOL is blocked, call HP technical support.

Procedure to Complete the Pool-Related SIMs

When the usage rate of the pool exceeds the threshold, or when the pool becomes blocked, the

following SIMs (Service Information Messages) will occur.

• When the usage rate of the pool exceeds the threshold: Reference code 601XXX

• When the pool becomes blocked: Reference code 602XXX

XXX indicates the pool ID. For details about the SIM reference codes, call HP technical support.

You can reference the SIMs occurring in the storage system through the window of Remote Web

Console. For details about the window, see the HP StorageWorks XP24000/XP20000 Remote

Web Console User Guide.

If you complete a SIM, the status of the SIM changes to completed. After the problem that caused

the SIM is solved, complete the SIM and change its status to completed. To complete the SIMs that

occur when the usage rate of the pool exceeds the threshold or when the pool becomes blocked:

1. Change the status of the pool whose usage rate exceeds the threshold to normal, and restore

the blocked pool to change its status to normal. For information about the solutions when the

pool usage rate exceeds the threshold and the pool becomes blocked, see “Troubleshooting

for XP Snapshot” (page 99).

2. 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 about how to change the mode, see the HP

StorageWorks XP24000/XP20000 Remote Web Console User Guide.

3. Display the Pool window.

4. Select the SIM Complete Request check box.

5. Click Apply. The confirmation message indicating if it is OK to apply the setting to the storage

system is displayed.

6. Click OK. The confirmation message closes and the SIM completion process begins. It takes

time if there are many SIMs to be completed.

You can check whether the SIMs are completed successfully in the window of Remote Web Console.

For details, see the HP StorageWorks XP24000/XP20000 Remote Web Console User Guide.
