Nope.  Not deemed feasible at the time they were put into production
and getting approval to add them after the fact and roll them out
to production would be prohibitive.  I did try the audit utility that IBM
provided from their website (I forget the name) and it managed to
hang the network connection on a perfectly good server (the failed drive
was the boot drive in another server) so the whole experience is starting
to sour me on IBM.

I don't like Dell, but they can actually tell you the serial number of the
drive(s) in your server given the server's serial number.  What the hell's
wrong with IBM?  One single character in my car's VIN tells me what
engine it has in it.  Another tells me both where it was made AND what
transmission it has in it.  What's the point of a 16-digit model number
if it doesn't convey useful information about the item?  I know IBM
makes a lot of stuff, but I doubt they've made quadrillions of models.

4 of us support over 1000 servers in production.  We really don't need 1000
additional emails to comb through every day, 1000 extra IP addresses
to manage, etc.  We only have 2 or 3 drive sizes and 2 types (U320 or
2GB FC) so I think I finally have all the FRU data I need now but I wish
IBM was a little more on the ball.  Sometimes I can get the info they
lack with Google but they shouldn't even have to do that.

Nah, this one is RHEL4.
