pairsyncwait
Synchronization waiting command
Description
The pairsyncwait command is used to confirm that a mandatory write (and
all writes before it) has been stored in the DFW (write) cache area of the
RCU.
The command gets the latest P-VOL async-CA sequence # of the main
control unit (MCU) side file and the sequence # of the most recently
received write at the RCU DFW (with the correct CTGID, group or
raw_device
) and compares them at regular intervals.
If the RCU sequence # exceeds the value of the designated MCU sequence
# within the time specified, this command reports a 0 return code (meaning
P-VOL/S-VOL synchronization to the desired point is achieved).
The –nowait option shows the latest sequence # (Q-marker) of the
designated MCU P-VOL and CTGID. The Q-marker is displayed in 10
hexadecimal characters.
