Hi,

What command you are using to reduce the volumes ?
You can use
lvreduce -m 0 /dev/vg00/lvol3 (To reduce the mirror copies of the root vol)
You cannot directly remove lvmtab entry.
What does lvdisplay -v /dev/vg00/lvol3 show ?
What error is it giving when you try to reduce root volume ?

You may have to force the removal of mirror, but use this option carefully and ensure backups/ignite tapes. Also see man lvreduce.
lvreduce -m 0 -k /dev/vg00/lvol3 /dev/dsk/c1t0d0
(Assuming the mirrored volume you want to remove from the PV /dev/dsk/c1t0d0).

Hope this helps,
Ninad

If you have a host disk issue that you are not able to remove, take a look at Technical Knowledge Base document #LVMKBRC00006257

Hi,

If you just run "vgexport , it will remove the disks from your /etc/lvmtab.

GoodLuck
