All of the pairs in the CG are deleted.
2. Check the pair status to make sure that the volumes are unpaired. To do this, run one of the

ICKDSF
You can run the commands to the P-VOL or S-VOL. If the P-VOL is paired with more than one S-VOL,
the status that is shown is for the pair that has an S-VOL with the lowest LDEV ID. To show the status
for a pair that has another S-VOL, run the command to the desired S-VOL.
If the storage system contains both BC Z and Cnt Ac-S Z pairs, the commands show the Cnt Ac-S
Z pair status. To show the BC Z status, run the command to the BC Z S-VOL. If you are sharing BC
Z and Cnt Ac-S Z volumes, path status shows for Cnt Ac-S Z. If they do not share volumes, path
status for the BC Z pair shows as FFFF FFFF.
