Perfectly right. Go ahead. Take the backup of all before you do all this.(In case is something goes wrong)

I have a D class server running 10.20 that does not have a mirrored root
drive. I have the drive and am going to have it installed soon. I have
culled the instructions on how to do the mirroring from a couple of
different sources so I wanted to get some feedback on my plan. Does it look
good? Are there things that I can do differently? More efficiently?
Thanks in advance and I will summarize.
1/ pvcreate -B /dev/rdsk/cXtXdX
2/ vgextend /dev/vg00 /dev/dsk/cXtXdX
3/ mkboot /dev/rdsk/cXtXdX
mkboot -a "hpux" /dev/rdsk/cXtXdX
lifcp /dev/rdsk/cXtXdX:AUTO -
^== To verify the contents of the auto file
4/pvdisplay -v /dev/dsk/c0t6d0
^== To check the order of the LVs on the original disk
lvextend -m 1 /dev/vg00/lvol1 /dev/dsk/cXtXdX
lvextend -m 1 /dev/vg00/lvol2 /dev/dsk/cXtXdX
lvextend -m 1 /dev/vg00/lvol3 /dev/dsk/cXtXdX
lvextend -m 1 /dev/vg00/lvol4 /dev/dsk/cXtXdX
lvextend -m 1 /dev/vg00/lvol5 /dev/dsk/cXtXdX
lvextend -m 1 /dev/vg00/lvol6 /dev/dsk/cXtXdX
lvextend -m 1 /dev/vg00/lvol7 /dev/dsk/cXtXdX
lvextend -m 1 /dev/vg00/lvol8 /dev/dsk/cXtXdX
pvdisplay -v /dev/dsk/cXtXdX
^== To make sure they are in proper order on the new disk
5/ setboot -a "Hardware Address of New Disk"
setboot
^== To check that the path is set correctly
6/ lvlnboot -r /dev/vg00/lvol3 /dev/vg00
lvlnboot -b /dev/vg00/lvol1 /dev/vg00
lvlnboot -s /dev/vg00/lvol2 /dev/vg00
lvlnboot -d /dev/vg00/lvol2 /dev/vg00
lvlnboot -v ( check output again)
7/ Shutdown interrupt PDC and boot from the alternate mirror.
8/ If successful change the auto file on the original disk
mkboot -a "hpux -lq" /dev/rdsk/c0t6d0
lifcp /dev/rdsk/c0t6d0:AUTO -
^== To verify the contents of the auto file.
9 Shutdown and boot off the primary.
Again, thanks in advance.
Regards,
Rob Smith
