Re: HP-UX root disk redundancy

a couple of methods...

setboot -a
if you get two entries primary and secondary that means disks are mirrored.

lvdisplay /dev/vg00/lvol*|grep -i mirror

if mirror copies is more than 0, it means its mirrored.

# lvlnboot -v

# setboot

# lvdisplay -v /dev/vg00/...


Test:

Very best would be to create a hardware RAID using the internal LSI chip.

Hope this helps!
