Root drive mirror question

Hello All,

Just wanted to your opinions on how my "/dev/vg00" primary drive (c1t6d0) has been
mirrored to drive (c2t6d0). Does all look ok?
I noticed the "/stand/bootconf" only has the primary drive (c1t6d0) added, and the "lifcp"
command shows the filename "PAD". I believe the "PAD" came from a "mkboot" command I had in a mirror script. Does all look ok to you?

You still need to add the additional disk to the /stand/bootconf file.

The PAD on the secondary disk looks ok, the same as mine. The rest should be ok. Also check that both disks are listed in 'setboot -v'

If you just add your mirror disk to /stand/bootconf file, I think you should be good.

PAD is just a space filler. So dont worry about that file missing from the lif volume.

Otherwise, the above output looks OK to me.

I'm providing a complete guide in case you missed something else.

pvcreate -B /dev/rdsk/c1t0d0 #use real disk

mkboot -l /dev/rdsk/c1t0d0
mkboot -a "hpux -lq (;0)/stand/vmunix" /dev/rdsk/c1t0d0 # use real disk

# mkboot -b /usr/sbin/diag/lif/updatediaglif -p ISL -p AUTO -p HPUX -p PAD -p LABEL /dev/rdsk/c?t?d?

If you are running 64-bit OS:

# mkboot -b /usr/sbin/diag/lif/updatediaglif2 -p ISL -p AUTO -p HPUX -p PAD -p LABEL /dev/rdsk/c?t?d?

vgextend /dev/vg00 /dev/dsk/c1t0d0 # same thing
lvextend -m 1 /dev/vg00/lvol1 /dev/dsk/c1t0d0

# real disk. repeat for other lvols

lvlnboot -r /dev/vg00/lvol3 # root fs /
lvlnboot -s /dev/vg00/lvol2 #swap
lvlnboot -d /dev/vg00/lvol2 #swap/dump
lvlnboot -b /dev/vg00/lvol1
lvlnboot -R
lvlnboot -v
setboot
setboot -a 52.1.0 # second disk

Good Luck
