Okay. this explains the difference. I guess my next question should be
is there a utility that actually does a quick check of the health of
all file servers in your cell?

Since we are so highly distributed between 4 campus, we could have
file servers on one campus that become unavailable. Since AFS does
such a good job at providing 'server independance', it would be nice
to have something that would explain why /afs/asu.edu/somewhere/in/afs
is not working..

Is there something thats part of the afs suite of utilies, or has
someone already scripted it?
