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 both primary and the secondary systems.
Prerequisite information
The volume must be unpaired.
