oh.. missing details:

HP-UX 11.11, fresh install, just patched up to June 2004

Could their be a share lib that vgdisplay needs to run?

Hi Eric,

what does ll say about the owner and group

# ll /usr/sbin/vgdisplay

[Rodney Hills]

Here is a trace of the open statements executed by vgdisplay-

open("/usr/lib/dld.sl", O_RDONLY, 03560) ..................................................................... = 3
open("/opt/graphics/OpenGL/lib/libogltls.sl", O_RDONLY, 0) ................................................... ERR#2 ENOENT
open("/usr/lib/libc.2", O_RDONLY, 0) ......................................................................... = 3
open("/usr/lib/libdld.2", O_RDONLY, 0) ....................................................................... = 3

Could it be possible you have a corrupted group file? You don't even need root to run /usr/sbin/vgdisplay vg00.

or a possible nfs problem.

Bingo.. somehow the owner/group on the VG and LV commands got changed. Now I'm trying to figure out if it was the error of my fingers or a script.

Wow....R-J was doing some *serious* bunny hunting there.
Great shot my friend - great shot.

Cheers,
