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 should not need to use
this procedure. A recovered pool can be used, but the former data is lost.
1.
In the Remote Web Console main window, in the Storage Systems tree, select Pool.
The pool name appears below Pool.
2. From the Pool table, select the pool to be recovered.
3. Click More Actions, and then select Restore Pools.
4. In the Confirm window, confirm the settings, in Task Name type a unique name for this task
or accept the default, and 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 THP V-VOL usage. Allow roughly
20 minutes of recovery time for every 100 TB of pool or THP V-VOL usage. Recovery time may
vary depending on the workload of the storage system at the time of recovery.
Decrease pool capacity
About decreasing pool capacity
You can decrease pool capacity by deleting pool-VOLs.
When a pool-VOL is removed from a pool, all the used pages in the pool-VOL are moved to other
pool-VOLs.
When you delete a pool or decrease the pool capacity, the released pool-VOLs (LDEVs) will be
blocked. If they are blocked, format them before using them. If the blocked pool-VOL is an external
volume, use Normal Format when formatting the volume.
You can decrease pool capacity for up to eight tasks at the same time. Do not execute a RAID
Manager command to also decrease the capacity of the pool whose capacity is already in the
process of being decreased.
You cannot decrease pool capacity while doing any of the following to a pool.
•
Creating the pool.
•
Deleting the pool.
•
Increasing the pool.
•
Decreasing the pool.
•
Recovering the pool.
•
Stopping decreasing the pool.
•
Changing the threshold.
•
Reclaiming zero pages.
