after redecing mirror disk
for patch test, I reduced mirror disk like this.
# vgdisplay –v /dev/vg01 로 확인
# strings /etc/lvmtab
# lvreduce –m /dev/vg01/lvol1 /dev/dsk/c0t6d0
# lvreduce –m /dev/vg01/lvol2 /dev/dsk/c0t6d0
# vgreduce /dev/vg01 /dev/dsk/c0t6d0
# strings /etc/lvmtab으로 확인
# lvdisplay –v /dev/vg01/lvol1로 확인
# lvdisplay –v /dev/vg01/lvol2로 확인
and how should I sync with original disk?
# vgdisplay –v /dev/vg01 로 확인
# strings /etc/lvmtab
# lvreduce –m /dev/vg01/lvol1 /dev/dsk/c0t6d0
# lvreduce –m /dev/vg01/lvol2 /dev/dsk/c0t6d0
# vgreduce /dev/vg01 /dev/dsk/c0t6d0
# strings /etc/lvmtab으로 확인
# lvdisplay –v /dev/vg01/lvol1로 확인
# lvdisplay –v /dev/vg01/lvol2로 확인
and how should I sync with original disk?

Re: after redecing mirror disk
Hi,
To sync with original disk, just follow the steps below :
# vgextend /dev/vg01 /dev/dsk/c0t6d0
If the command above not work, you need to create a physical volume first before vgextend :
# pvcreate -f /dev/rdsk/c0t6d0
After that do re-mirror again :
# lvextend -m 1 /dev/vg01/lvol1 /dev/dsk/c0t6d0
# lvextend -m 1 /dev/vg01/lvol2 /dev/dsk/c0t6d0
Check the mirror :
# lvdisplay -v /dev/vg01/lvol1
# lvdisplay -v /dev/vg01/lvol2
For details of the commands, check the man page of the command :
# man pvcreate
# man vgextend
# man lvextend
Hope this information can help you.
Cheers,
AW
