I've been working with HP-UX for a long time. I have never seen anything like that. Here is the bdf output from two different HP-UX systems:

Code:

Can you tell me anything at all about the physical disks involved? One of the system has MirrorDisk/UX installed; and on that system, vg00 is mirrored. Which system? The HP-UX /dev/vg00/lvol1 and the SunOS /dev/md/dsk/d2 are actually rather close in concept. In both cases you need another command to trace back to the physical disk. Now looking at the SunOS "df -k" output...
Code:
Filesystem            kbytes    used   avail capacity  Mounted on
/dev/md/dsk/d0        493688   50002  394318    12%    /

/dev/md/dsk/d7       2622176 1864275  705458    73%    /export
/dev/md/dsk/d6        736904    3430  674522     1%    /opt

the main difference that strikes me is "capacity" verses "%used".

vgimportclone

VGIMPORTCLONE(8)					      System Manager's Manual						  VGIMPORTCLONE(8)

NAME

       vgimportclone - import and rename duplicated volume group (e.g. a hardware snapshot)

SYNOPSIS

       vgimportclone [-n|--basevgname VolumeGroupName] [-i|--import] PhysicalVolume [PhysicalVolume...]

DESCRIPTION

       vgimportclone is used to import a duplicated VG (e.g. hardware snapshot).  Duplicate VG(s) and PV(s) are not able to be used until they are
       made to coexist with the origin VG(s) and PV(s).  vgimportclone renames the VG associated with the specified PV(s) and changes the  associ-
       ated VG and PV UUIDs.

OPTIONS

       See lvm for common options.

       -n|--basevgname VolumeGroupName
	      By  default  the	snapshot  VG  will be renamed to the original name plus a numeric suffix to avoid duplicate naming (e.g. 'test_vg'
	      would be renamed to 'test_vg1').	This option will override the base VG name that is used for all  VG  renames.	If  a  VG  already
	      exists with the specified name a numeric suffix will be added (like the previous example) to make it unique.

       -i|--import
	      Import exported Volume Groups.  Otherwise VGs that have been exported will not be changed (nor will their associated PVs).

ENVIRONMENT VARIABLES

       LVM_BINARY
	      The LVM2 binary to use.  Defaults to "lvm".

EXAMPLES

       The  origin VG vg00 has origin PVs /dev/sda and /dev/sdb and the respective snapshot PVs are /dev/sdc and /dev/sdd.  To rename the VG asso-
       ciated with /dev/sdc and /dev/sdd from vg00 to vg00_snap (and to change associated VG and PV UUIDs) do:

	    vgimportclone --basevgname vg00_snap /dev/sdc /dev/sdd
