LSS 2D00 has an active Global Mirror volume but it is not the Master LSS. Therefore,
RQUERY in Example 26-3 does not provide session summary information although both
LSSs reside in the very same primary storage disk subsystem. Note that the decision of
which LSS is the Master LSS, is made when the Global Mirror session is started.
Example 26-4 shows an example of the formatted output of the RQUERY command with the
ACTION(GMLSTAT) parameter specified.

This is the active Global Mirror session as was shown in Figure 26-1 on page 342. During
these queries, a write workload was running on all three Global Mirror primary volumes.
26.2.4 Global Mirror session status for each LSS - GMPSTAT option
The ACTION(GMPSTAT) option returns Global Mirror session information with volume
counts, and out-of-sync tracks information, related to the addressed LSS.
