Legend:

Accepted = Accepted and executed. When the operation terminates normally, the status changes to the indicated number.

Acceptable = Accepted but no operation is executed.

Rejected = Rejected and operation terminates abnormally.

Pairsplit of a Continuous Access Asynchronous volume is returned after verification of state transition
that waits until delta data is synchronized from P-VOL to S-VOL.

NOTE:

In the case of the SSWS status after S-VOL-SSUS-takeover execution, the pairresync

command (from P-VOL to S-VOL) is rejected because the delta data for S-VOL becomes dominant,
and its status is expected to be using the -swaps(p) option of pairresync. If the pairresync command
(from P-VOL to S-VOL) is rejected, confirm this special status using the -fc option of the pairdisplay
command.

The following table shows the relation of command acceptances for paired status and Business
Copy.
