Figure 19 Example of -FMRCF option for Pairevtwait
Using -ss <status> ... and -nowaits option In P-VOL_PSUS & S-VOL_COPY state of HOMRCF quick
mode, pairevtwait will return immediately even if the S-VOL is still in S-VOL_COPY state because
P-VOL is already in P-VOL_PSUS state. If you want to wait the S-VOL_SSUS state, then use -ss
<status> and -nowaits option in order for waiting the pair status on S-VOL side. This is needed for
operating pairresync -restore or pairsplit -S.
The figure below shows five examples of waiting until “P-VOL_PSUS” & “S-VOL_COPY” state is
changed to S-VOL_SSUS.
Figure 20 Example of waiting for Business Copy
The horctakeover command suspends G2(CA-Jnl) automatically if horctakeover returns
“Swap-takeover” as an exit code. In DC1 host failure, if APP1 wants to wait until DC3 becomes
the suspend state, then they can verify the “SSUS” state by using the pairevtwait command as
shown below.

pairmon
The pairmon (pair monitor) command, which is connected to the HORCM daemon, obtains the
pair status transition of each volume pair and reports the status change. If the pair status changes
(due to an error or a user-specified command), the pairmon command displays a message.
