Figure 24-15 ICKDSF - query session information and CG failure report
Figure 24-15 shows an ICKDSF query command of a Global Mirror session and its edited
output. The Master LSS is pointed to by the DDNAME volume serial. This query command
provides two reports:
򐂰 Under Session Information you find details on forming Consistency Groups. In the table
you also find the Global Mirror session tunable variables that are active.
򐂰 The Consistency Group Failure Report provides information about why forming
Consistency Groups failed. Example 24-32 provides the corresponding legend to
understand the codes that are shown in this report.
