Forcibly deleting pairs
You need to 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 storage system due to a communication error. In this case, you need to delete the pair forcibly in both the primary storage system and the secondary storage system.
Before you begin
The volume must be unpaired.
