Anyone ever seen this error?

We started getting it after an unsuccessful "splitlvcopy" command.
synclvodm did not help. There are no missing disks. A reboot did not
fix the problem.

syncvg -l livelv
0516-1295 lresynclv: Unable to completely resynchronize volume.
The logical volume has an active backup copy.
This may have caused the command to fail.
0516-934 /etc/syncvg: Unable to synchronize logical volume livelv.

Any suggestions would be welcome.

FOLLOW-UP:

Here is what we found out. The error message is generated because the
mirrored JFSLOG area is keeping an incorrect copy of the mirrored
logical volume partitions.

When we tried to flag the partitions as not belonging to a split
mirror, we got the following error:

chlvcopy -f -B livelv
0516-304 getlvodm: Unable to find device id 00011016988f2d22.24 in the
Device
Configuration Database.
0516-304 getlvodm: Unable to find device id 00011016988f2d22.24 in the
Device
Configuration Database.
0516-312 getlvodm: Unable to find logical volume 00011016988f2d22.24
in the Devi
ce
Configuration Database.
0516-912 rmlv: Unable to remove logical volume 00011016988f2d22.24.


A search using "odmget CuAt" showed no traces of the lv with ".24" so
it was assumed to be coming from somewhere else. Since the jfslog is
used to track the two copies, we figured it must be in there. So
instead of doing the rmlvcopy on the livelv, we did the rmlvcopy on
the livelv jfslog. This worked.

Then, on an unmounted livelv, we were able to rmlvcopy the backup copy
which was giving errors before. BTW - If you don't unmount it, you get
these errors:

rmlvcopy livelv 1
0516-1178 lreducelv: Cannot extend or reduce logical partitions
with an active backup mirror copy.
0516-922 rmlvcopy: Unable to remove logical partition copies from
logical volume livelv.


All that was left was to mklvcopy the areas again and syncvg the lv's.

Hope this may help someone else who gets this scenario.

what level of code are you running ? IY44289 AIX 5.1 or IY55531 AIX
5.2 both deal with 0516-1295 from syncvg and split mirror copying.

We are on AIX 5.1.0.0 ML4. I am going to install ML6 before trying the
splitcopy again. We had a similar problem (not same error) in the past
on AIX 5.1 and IBM actually had to prepare a hotfix for the issue. It
should have made it into the latest ML by now ;-)

Thanks for the APARs though, will keep them in mind when we migrate.
