Workflow for recovering blocked pools

When a pool is blocked, you must recover the pool volume, pool, Thin Image pairs, and then V-VOL in that order. This section describes how to recover a blocked pool.

• Recovering blocked pool volumes

  When a pool volume is blocked, contact the Hitachi Solution Support Center.

• Recovering the pools

  Recover the pool by using one or both of the following methods:

  • Add additional pool-VOLs.
  • Decrease the pool usage rate by deleting the P-VOL's snapshot data.

• Recovering Thin Image pairs

  When a pool is blocked, all Thin Image pairs that contain snapshot data of the blocked pool switch to the PSUE status. To recover these pairs, delete and then re-create them.

Related Tasks

• Resynchronizing Thin Image pairs

  You can resynchronize Thin Image pairs that you have split or that the storage system has suspended.

• Deleting Thin Image pairs

  Delete Thin Image pairs when you do not need them or when you want to delete snapshot data.

• Increasing pool capacity

  Adding pool-VOLs to a pool increases, or expands, the pool’s capacity. Check the pool’s available capacity and expand the pool as needed.

• Recovering blocked pools

  You can recover blocked pools using the Restore Pools window.

• Managing pools

  Use Thin Image to manage pools, such as monitoring information about a selected pool (for example, the LDEV ID and Used Pool Capacity), viewing used pool capacity by pool or by the Thin Image pair's root volume, viewing the progress of rebalancing the pool usage rates among parity groups, increasing pool volume by adding pool-VOLs to a pool, decreasing the pool volume, and monitoring the pool usage rate.
