Figure 4.13 Example of -FMRCF Option for Pairevtwait
Using -ss ... and -nowaits option
In PVOL_PSUS & SVOL_COPY state of HOMRCF quick mode, pairevtwait will return
immediately even if the S-VOL is still in SVOL_COPY state because PVOL is already in
PVOL_PSUS state. If you want to wait the SVOL_SSUS state, then use -ss and
-nowaits option in order for waiting the pair status on SVOL side. This will be needed for
operating pairresync -restore or pairsplit -S.
The figure below shows five examples of waiting until “PVOL_PSUS” & “SVOL_COPY” state
will be changed to SVOL_SSUS.
