HP XP RAID Manager Software - Manual (Page 159)

To terminate this status, re-execute the RAID Manager command, then terminate suspending/deleting
status after “JNL Consistency Restore”.
(8) Detecting inconsistent CTQ-Marker
The pairsplit command checks data consistency with CTQ-Marker across multiple DKCs. If an
inconsistent CTQ-Marker is detected, then it returns with EX_VOLCUR after changed to suspend
status.
This error needs to confirm if CTQMs are the same on S-VOL on each DKC using the “pairdisplay
-v jnl -fe” option.
# pairdisplay -g horc0 -v jnl -fe

(9) About pairsyncwait command
Using the Q-Marker with the pairsyncwait command is managed on each Journal including
the target device. Therefore the pairsyncwait command must specify a target device (-g
-d , or -d , or -d ). For example:
# pairsyncwait -g horc0 -d dev-002 -t 500
UnitID CTGID Q-Marker Status Q-Num
1 0 0000003de8 DONE 0
If group (-g ) is specified, then the first dev_name on the specified group is used.
Explanation of terms:
•
JNL Consistency Restore: commits up as far as MAX CTQ-Marker.
•
JNL Full Restore: commits up to EOM (End of marker for split).
•
JNL Consistency Suspend: suspends after “JNL Consistency Restore”
•
JNL Full Suspend: suspends after “JNL Full Restore”
Configuration examples
RAID Manager does not change the command options for supporting Continuous Access Journal
MxN Open. However the output of the command is added so that the command can display the
CT group and Q-Marker for each DKC, because the CT group and Q-Marker are managed on
each DKC.
