Recovering a blocked pool

The Storage Administrator (Provisioning) role is required to perform this task.

This procedure is for failure recovery of a blocked pool. Ordinarily, you do not need to use this procedure. A recovered pool can be used, but the former data is lost.

For Command Suite:

• On the Resource tab, expand the Storage Systems tree. Right-click DP Pools of the target storage system, then select System GUI.

For Storage Navigator:

• In the Storage Systems tree on the left pane of the main window, select Pools.

2. From the Pools table on the right, click the row of a pool you want to change to the Dynamic Tiering setting.

3. Perform one of the following to display the Restore Pools window.

• Click More Actions and select Restore Pools.

• Click Actions > Pool > Restore Pools to open the window.

4. In the Confirm window, confirm the settings, in Task Name type a unique name for this task or accept the default, then click Apply.

If Go to tasks window for status is checked, the Tasks window opens.

The recovery time for pools varies depending on pool usage or DP-VOL usage. Allow roughly 20 minutes of recovery time for every 100 TB of pool or DP-VOL usage. Recovery time can vary depending on the workload of the storage system at the time of recovery.
