HP XP P9000 RAID Manager Reference Guide (T1610-96061, January 2014)

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.
The pair status transition events exist in the HORCM pair state transfer queue. The -resevt option
(reset event) deletes one/all events from the HORCM pair state transfer queue. If reset event is not
specified, the pair state transfer queue is maintained. If the -s option is not specified, pairmon
displays all events for which it receives information from HORCM. If the -s option is specified, only
the specified status transitions are displayed.
The RAID Manager software supports the error monitoring and configuration confirmation commands
for linkage with the system operation management of the UNIX server.

be reported, one event is reported and the event is reset. If there is no pair status transition information

-nowait options.
