LVM error

Hi Experts,

I had one disk(Hot Swappable) replacement activity. disk was mirrored. without breaking mirror disk was replaced by HP-FE. Stale lvols were there. Then I tried to first remove disk from vg00. But got the following error.

===========================================

cow08157:root vgreduce vg00 /dev/dsk/c2t0d0
vgreduce: Physical volume "/dev/dsk/c2t0d0" could not be removed since some of its
physical extents are still in use.

=======================================

Then i tried to break the mirror.
cow08157:root lvreduce -m 0 /dev/vg00/lvol7 /dev/dsk/c2t0d0
Usage: lvreduce
[-A Autobackup]
{-l LogicalExtentsNumber |
-L LogicalVolumeSize}
[-f]
LogicalVolumePath
"m": Illegal option.

Please suggest and how to proceed as it is production box.

Regards
kris

Hi,

you should use lvchange instead of lvreduce

Turn the mirror write cache off on a logical volume:

lvchange -M n /dev/vg01/lvol1

Hi,
if you are getting the error message like "m": Illegal option " then there will not be mirror license. please check do you have the mirror license or not...

Thanks,
Shan.
