• With Cnt Ac-J Z, you can delete pairs when split time is set for an BC Z consistency group.
The specified split time is deleted when you delete the following pairs:
◦ All BC Z pairs belonging to the BC Z consistency group.
◦ All Cnt Ac-J Z pairs belonging to the Cnt Ac-J Z restore journal.
At-Time Split and supported pair statuses
The pair status for all of the BC Z pairs in the consistency group determines if you can perform
At-Time Split. If all of the BC Z pairs in the consistency group are paired (DUPLEX status), you can
perform At-Time Split.
The following table shows when you can perform At-Time Split based on the BC Z pairs in the
consistency group that are not paired (a status other than DUPLEX), and the resulting pair status
after you perform At-Time Split.

NOTE:
1
If you share the Cnt Ac-J Z S-VOL and the BC Z P-VOL, the command may end normally after you perform
the At-Time Split. Ensure the status of the pairs within the consistency group have changed to “Split/SUSPOP” (use the
pairdisplay command).
2
Consistency is guaranteed only for BC Z pairs in “DUPLEX” or “PENDING” status.
