HP XP Racks - Manual (Page 28)

Consistency is preserved for the consistency group if the execution results of the YKQUERY command
are one of the following:
•
All the copy pairs are in the DUPLEX status.
•
All the copy pairs are in one of the following suspended statuses, and the diagnosis information
value of all copy pairs is x'04':
◦
SUSPOP
◦
SUSPCU
◦
SUSPER
◦
SWAPPING
Consistency is preserved even when the representative consistency delta value of the entire copy
group can be obtained. The representative consistency delta value of the entire copy group can
be obtained if consistency is preserved for all the consistency groups in the copy group and the
consistency time can be obtained.
For details on copy pair statuses, see “Using CLI commands to obtain status” (page 78) . For details
on consistency delta, see “Consistency times and consistency delta values” (page 32) .
The table below explains how to check the YKQUERY command execution results. For details on
REXX variables and ISPF panels, see the HP XP7 for Business Continuity Manager Reference Guide.
ISPF panel REXX variable Value to check
Copy Group Pair Status panel (for each
copy pair) stem.CopyGroup.n.Pair.n.State Copy pair status
Copy Group Status Summary panel (for
each copy group)
-- stem.CopyGroup.n.Pair.n.Diagnosis Diagnosis information
Copy Group Status Summary panel stem.CTDelta Representative consistency delta value
CAUTION:
•
You need to obtain information from the S-VOL to obtain the diagnosis information or
consistency delta value.
•
If the ATTIME Suspend Function is used, a representative consistency delta value is not set for
the entire copy group. Verify that consistency is preserved by making sure that the entire copy
group changes to the SUSPOP status.
NOTE: Note: stem refers to the prefix of the REXX variable structure.
Open/MF consistency groups
When the Open/MF Consistency Preservation Function is used for Continuous Access Synchronous
Z consistency groups, open-system copy groups and mainframe-system copy groups within the
same consistency group can be suspended at the same time. This preserves consistency between
mainframe-system copy groups and open-system copy groups within the same consistency group.
An Open/MF consistency group is a consistency group that uses the Open/MF Consistency
Preservation Function and contains open-system and mainframe-system copy groups.
Figure 4 (page 29) shows the effect of suspending an Open/MF consistency group.
