i thought it was only volume groups that can not be reduced. or was that only logical groups?
i really wanna say its the VG that is a static. IE: you can add and swap disks but you cant make it smaller w/ out removeing it and recreateing it.
mmmmmm makes me go back to my aix documention. i know its not hp-ux but its the only other os i have that uses a "smarter disk management system"

I have a SunOS 5.8 server. I suspect there may be errors with one of the physical disks (based on someone reporting hearing a "clicking sound" during the night shift, however I do not hear anything this morning).
Which log would show this?
