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 secondary system because of a communication error. In this case, delete the pair forcibly in the both the primary and the secondary systems.

 The following data will be deleted:

• Data that has not been sent to the secondary system if the pair is forcibly deleted from the primary system.

• Data that has not been restored if the pair is forcibly deleted from the secondary system.

Also, if a pair with the PAIR/COPY status exists in the journal group when forcibly deleting, host I/O to that pair might time out.

Prerequisite information

• The volume must be unpaired.
