Example 24-19 shows for this status
Services, SC35-0428, for a description of different status indications.
Example 24-20 shows Global Mirror status information for a particular LSS and its Global
Copy primary volumes, when ACTION(GMPSTAT) is used with the RQUERY command.

The formatted output provides the following information:
LSS number 0D contains 2 volumes in the session number 01 (SNbr, LSS, and TotVol).
Both volumes contain tracks that are not yet replicated by Global Copy to their
corresponding secondary volumes (OOSVol).
The number of out-of-sync tracks is indicated in hexadecimal (OOSTrks).
Consistency Group formation is in process for this LSS (GMPStatus).
Example 24-21 shows two TSO RQUERY commands with ACTION(DVCSTAT). One
command is addressed to LSS 0C and the other to LSS 0D. They both show, for the
corresponding LSS, individual information for the Global Copy primary volumes that are in the
Global Mirror session. These devices are: device with CCA x'00' in LSS x'0C', and devices
with CCA x'00' and x'01' in LSS x'0D'.

Example 24-21 shows that the volumes in both LSSs are still not in session, are in their initial
copy phase, and have not completed their first pass.
Example 24-22 on page 313 shows the very same RQUERY TSO commands as in the
previous example, but this time the initial copy phase is complete and all volumes are in
session, which means they participate in the Consistency Groups formation at the remote
site.
