----
For whatever its worth I tested one of my 2650's loaded with ES3
overnight.
The system has the newest kernel available from the errata provided by
Redhat (2.4.21-9EL).
What I did was:
while :; do
dd if=/dev/zero of=test count=3000000
rm -rf test
done
It creates a 1.5GB or thereabout file for me on my system, should you
have a different FS blocksize the size will change.
Anyway the system stayed up all night and still is at it.
I figured if something is wrong with the aacraid driver/IO subsystem I
should see it after a while doing this test.  Now I realize this doesn't
really take care of every case that can happen since this only tests
writes.
If anyone has a better idea on how to test the proper workings of a PERC
3/Di I'd appreciate your input.

This is exactly the issue I had. The system would just hang. It turned 
out to be a buggy aacraid driver (the adaptec RAID driver). I ended up 
getting a kernel patch from Adaptec.
I don't know if this is still an issue with the latest redhat releases, 
I suspect is probably still is. I would check the mailing lists on 
linux.dell.com (there's an aacraid-specific list).
It's a shame that a system that's RedHat certified, running an OS 
that's Dell certified, just doesn't work.
