Forcibly deleting pairs
You forcibly delete a pair 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. In this case, delete the pair forcibly in both local and the remote storage systems.
CautionThe following data is discarded:
- 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.
