IBM x345 + EXP400

[eric]

I've been reading some older posts to figure out how to get either
4.10 or 5.2.1 running on an IBM x345. Here's what is in this
particular machine...

x345, 6 internal 10k 146GB disks.
An internal U320 LVD SCSI Adapter
An EXP400 External Array with 14x146 10k drives

What I found was this...

But I'm curious to know...

a) does this work for arrays setup using the ServerGuide
configuration CD delivered with the hardware?
b) does all this actually work? :)
c) what kind of error reporting is there, if it works, to the
Operating System? 

Hopefully we won't have to go the "luser unix route"

Thanks.
