Steps to replace faulty root disk mirror
===================================

----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
EXAMPLE 1:
***********
1) Remove lvol mirrors:
# lvreduce -m 0 /dev/vg00/lvol2 /dev/dsk/c2t6d0
# lvreduce -m 0 /dev/vg00/lvol1 /dev/dsk/c2t6d0
2) Remove faulty drive from vg00:
# vgreduce /dev/vg00 /dev/dsk/c2t6d0
replacement of hot-swappable drive c2t6d0 at H/W path 0/0/2/1.6.0:
SCSI describe of /dev/rdsk/c2t6d0:
vendor: HP 36.4G
product id: ST336706LC
type: direct access
size: 35566480 Kbytes
bytes per sector: 512
4) When drive is replaced, add back into vg00 and make bootable:
# ioscan -fnC disk
# pvcreate -B /dev/rdsk/c2t6d0
# vgextend /dev/vg00 /dev/dsk/c2t6d0
# mkboot -l /dev/rdsk/c2t6d0
5) Re-mirror logical volumes, must be done in lvol order:
# lvextend -m 1 /dev/vg00/lvol1 /dev/dsk/c2t6d0
# lvextend -m 1 /dev/vg00/lvol2 /dev/dsk/c2t6d0
# lvextend -m 1 /dev/vg00/lvol3 /dev/dsk/c2t6d0
And repeat for remaining logical volumes lvol4 through lvol13.
