I see now the correct LVs again.
File /etc/fstab was correct, /etc/mnttab was wrong.
I solved the problem with

  $ mv /etc/mnttab /etc/mnttab.prev
  $ mount -a

This probably arrived after booting in maintenance
mode, and then shifting to an higher run level
without rebooting.
Boot definitions for vg00 are correct:

  $ lvlnboot -v vg00
  Boot Definitions for Volume Group /dev/vg00:
  Physical Volumes belonging in Root Volume Group:
          /dev/dsk/c1t2d0 (0/0/1/1.2.0) -- Boot Disk
  Boot: lvol1 on: /dev/dsk/c1t2d0
  Root: lvol3 on: /dev/dsk/c1t2d0
  Swap: lvol2 on: /dev/dsk/c1t2d0
  Dump: lvol2 on: /dev/dsk/c1t2d0, 0

Best regards,
Stefano

Object: [HPADM] Why /dev/root instead of /dev/vg00/lvol3 ?

Once upon a time,
the bdf command gave me an output like this

Filesystem kbytes used avail %used Mounted on
/dev/vg00/lvol3 143360 31201 105181 23% /
/dev/vg00/lvol1 83733 28748 46611 38% /stand
...

Now I see /dev/root for the lv mounted on / :

Filesystem kbytes used avail %used Mounted on
/dev/root 143360 31201 105181 23% /
/dev/vg00/lvol1 83733 28748 46611 38% /stand
...

Why? I don't like it at all.
This appears on both our hp-ux 11.00 servers.
Does this means I have now different data
mounted on / ?
Where comes this /dev/root and /dev/rroot files
from, and why and how to see the correct lvs again?

Thank you and best regards,
Stefano
