Hi,
I presume you want to mirror the bootdisk ?
Here goes :
pvcreate -B /dev/rdsk/[second disk]
vgextend /dev/vg00 /dev/dsk/[second disk]
mkboot /dev/rdsk/[second disk]
mkboot -a "hpux -lq" /dev/rdsk/[second disk]
mkboot -a "hpux -lq" /dev/rdsk/[first disk]

lvextend -m 1 /dev/vg00/lvol1 /dev/dsk/[second disk]
lvextend -m 1 /dev/vg00/lvol2 /dev/dsk/[second disk]
lvextend -m 1 /dev/vg00/lvol3 /dev/dsk/[second disk]
... and so on, for all logical volumes on the boot disk ...

# As extra you might want to alter your alternate boot path

Regards,
Tom

Hi again,
Disregard my second answer. Don't know how that got there, but it has still got typos in the lvextend commands.

Tom
