/dev/vg00/lvol1 is actually your "root" or "/" filesystem.

/dev/root sometimes shows up if any work has been done in LVM maintenance mode.

The basic fix is:

# mv /etc/mnttab /etc/mnttab.old
# mount -a

Now do a 'bdf' and see if the "/" filesystem shows up correctly.

If that doesn't work have a look at this document in the HP Tech Knowledge base:

Hi Shrekanth,

As mentioned by the previous replier, the most likely reason will be that you have booted in maintanence mode. In this case
you don't have to worry much (unless there
was some other reason to boot -lm mode )
you can reboot the server in normal mode and
the bdf will show /dev/vg00/lvol1 as /.

check what runlevel you are currently.
# who -r [[ if it is > 2 then you are not in maintanence mode and this will not apply ]]

actually /dev/vg00/lvol3 is the root fs and /dev/vg00/lvol1 is /stand
