If you periodically issue XQUERY commands to the system, the consistency group time increases as long as the primary volumes continue to have update activity.
If update activity ceases for all volumes in the XRC session, the consistency group time does not change for uncoupled sessions. For coupled sessions, the consistency group time increases. In both cases, an XQUERY report displays an IDLE time that indicates how long application updates have been idle.
The consistency group time reported with XQUERY, XDELPAIR, XSUSPEND, XRECOVER, XEND, and XADVANCE messages is dependent on the status of the XRC volume pair at the time the message is issued. For active XRC volume pairs, the consistency group time reported is the consistency group time for the entire XRC session. For suspended XRC volume pairs, the consistency group time is the time that the volume pair was last consistent with the XRC session.
XRC may suspend a volume pair because of an error, or because you have suspended the volume with an XSUSPEND VOLUME or XSUSPEND TIMEOUT command. XRC reports a consistency group time for the volume pair that reflects the last consistency group that XRC secured on the secondary volume.
Other volume pairs in the XRC session continue to have update activity, and their consistency group time continues to advance. At any given moment, the latest timestamp indicates the last consistency group that XRC has successfully secured on the secondary volumes.
