*In the case of the SSWS state after SVOL-SSUS-takeover, the pairresync command (from PVOL to SVOL) is rejected because
the delta data for SVOL becomes dominant, and its state is expected to be using the -swaps(p) option of pairresync. If the
pairresync command (from PVOL to SVOL) is rejected, confirm this special state using the -fc option of the pairdisplay command.
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.
