Hi:

At 11.x, the "Managing Systems and Workgroups: A Guide for HP-UX System Administrators" guide is a excellent source of documentation on common system administration functions.

See Managing Mirrored File Systems in Section-6:

Have a look at this post for some information and also for a pretty usefull script to do the mirroring of a root disk.

Mirroring of a non bootable lvol is easier..

What seems to confuse people most when I teach them mirrordisk is that it actually does not mirror disks, but rather lvols which can be sections of disks or span multiple disks.

Hello,

after reading all these docs I would suggest to test the mirror before going in production.

Try to boot from alternate disk once to test it.

Hi,

If your trying to mirror your root volume
group (vg00) it is a very simple process.

The docs that the other guys have pointed
you to should assist you greatly, but here
is the concise process for doing this.

# pvcreate -fB /dev/rdsk/cXtXdX
# vgextend /dev/vg00 /dev/dsk/cXtXdX
# mkboot /dev/rdsk/cXtXdX
# mkboot -a "hpux -lq(;0)/stand/vmunix" /dev/rdsk/cXtXdX
# lvlnboot -R
# for LVOL in /dev/vg00/lv*
> do
> echo $LVOL
> lvextend -m 1 $LVOL
> done

As mentioned by Steffi make sure that you
test it before you proceed into any form
of production.
