The following figure shows the failure area and recovery when a pair is suspended due to a full pool of the S-VOL.



  1. Increase an available capacity to the pool on which the full pool was detected.

    For details on how to increase an available pool capacity, see the Provisioning Guide for the storage system.

  2. Confirm the quorum disk status. If the quorum disk is blocked, recover from the blockade. If you do not set a volume for the quorum disk, you can skip this step.
  3. Resynchronize a GAD pair.
    If a failure occurs after the one volume capacity of a GAD pair can be expanded, the creation, resync, swap resync, and horctakeover operations of the GAD pair cannot be performed because the capacity of both the volumes is not the same. Make sure to expand the other volume capacity so that the capacity of both the volumes is the same, and then retry the operation.
    1. Confirm that the I/O mode of the P-VOL is Local.

    2. At the primary storage system, resynchronize the pair. 
      pairresync -g oraHA -IH0
    3. Confirm that the P-VOL and S-VOL pair statuses change to PAIR (Mirror (RL)).

  4. Using the multi-path software, resume I/O to the S-VOL (I/O might resume automatically).
