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.

Rejected = Rejected and operation terminates abnormally.
In the following descriptions, when the pair statuses of P-VOL and S-VOL are different, P-VOL_ or
S-VOL_ are applied to show which volume is indicated.
