Deleting pairs

A TrueCopy pair can be deleted. Doing this deletes the TC relationship,
though not the volumes or their data.
• When it is no longer necessary to maintain a remote copy of the P-VOL,
delete a pair from the primary system only. All update operations are
stopped and pair status for both the P-VOL and S-VOL changes to
unpaired.
When a pair is deleted, the primary system continues to accept write I/O
to the former P-VOL but does not keep track of the updates.
• Delete a pair from the secondary system only for disaster recovery
purposes. When you do this, the secondary system changes the S-VOL
pair status to unpaired, and the primary system detects that the S-VOL
status is unpaired and then changes the P-VOL status to PSUS (Delete
pair to RCU).
To restart a pair that was deleted from the secondary system, you must
delete the pair from the primary system and then create the pair from the
primary system.
Note: When you delete a pair from the secondary system, make sure that
the S-VOL and P-VOL are identical, including the volume labels. Take all
necessary steps to prevent system problems due to duplicate volumes.
