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

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

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

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.

Great shot my friend - great shot.
