Table 4.48 lists and describes the pair synchronization waiting command parameters and
returned values. Table 4.49 lists and describes the error codes for the pairsyncwait
command. The pairsyncwait command is used to confirm that required writing was stored in
DFW area of RCU, and it will be able to confirm whether or not a last writing of just before
this command is reached to RCU DFW area. This command gets the latest sequence # of MCU
sidefile (PVOL latest sequence # within the CT group ID) and the sequence # of RCU DFW
within the CT group ID which correspond to the or that is specified by
pairsyncwait, and compares MCU with RCU sequence # at that time and at regular interval. If
RCU sequence # is over the value of MCU sequence # within the term that was specified by
pairsysncwait, this command reports the return code 0 with the meaning of completion of
synchronization. The -nowait option shows the latest sequence # (Q-marker) of MCU PVol
and CTGID. The marker is shown in hexadecimal of ten characters.
