24.5.8 Query an active Global Mirror session
Figure 24-14 shows an ICKDSF command to query the devices and their session status. At
the very moment when the query was done, a Consistency Group formation was going on.
Figure 24-14 ICKDSF - query devices in a Global Mirror session
The query also shows four volumes within the LSS indicated by DDNAME, that are also part
of the Global Mirror session. The first two volumes are in session (IS). The next two volumes
are defined to the session but they are in a join pending (JP) state, and they are not Global
Copy primary volumes (simplex, SX). This means the volumes have been added to the
session with the POPULATESESSION command, although these volumes are not Global
Copy primary volumes. This is indicated by the SX code.
