Pairsplit of a Hitachi TrueCopy Asynchronous volume will be returned after verification of
state transition that waits until delta data is synchronized from P-VOL to S-VOL.
Note: In case of the SSWS state after SVOL-SSUS-takeover, pairresync command (from
PVOL to SVOL) is rejected because the delta data for SVOL becomes dominant, and its state
expect to be using -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.
