You forcibly delete a pair using HDvM - SN for the following reasons:

  • A currently unpaired volume that was previously in a pair is unusable because previous pair information is still in the volume.
  • The pair cannot be connected to the remote storage system because of a communication error.
  • The pair cannot be deleted or a timeout error occurs even when no hardware failures occur and the processing load is low.

In the case of a communication error, delete the pair forcibly in both the local and the remote storage systems.

CAUTION:
The following data is discarded when you forcibly delete pairs:
  • Data which is not sent to the secondary storage system when a pair in the primary storage system is deleted forcibly
  • Data which is not restored when a pair is deleted forcibly in the secondary storage system

In addition, if a pair is deleted forcibly when a journal contains a pair in the PAIR/COPY status, host I/Os to the pair might time out.

  • The volume must be unpaired.
  • Required role: Storage Administrator (System Resource Management)
