pairsyncwait
The pairsyncwait command is used to confirm data consistency between the Continuous Access
Asynchronous/Cnt Ac-J P-VOL and S-VOL by confirming that required writing was stored in the
DFW area of RCU, and confirming whether the last writing just before this command reached the
RCU DFW area.
This command gets the latest sequence # of the MCU sidefile (P-VOL latest sequence # within the
CT group ID) and the sequence # of the RCU DFW within the CT group ID corresponding to the
<group> or <raw_device> specified by pairsyncwait, and compares the MCU with the RCU
sequence # at that time and at regular intervals. If the RCU sequence # is over the value of the
MCU sequence # within the term specified by pairsysncwait, this command displays 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 10
characters.
When a client issues the pairsyncwait command, this command is placed on the queue buffer for
waiting in the HORCM daemon as a command request. HORCM gets the latest sequence # from
the MCU sidefile and the sequence # whose block was transferred and stored in the DFW area
of RCU with data consistency, and compares the latest sequence # of MCU sidefile with the
sequence # of the RCU DFW area within the term. HORCM replies return codes to this command,
when the write of MCU sidefile was stored in RCU DFW area.
