I removed the Mylex controler, and since it's a production server,
I cannot do experiments on this one, so I cannot get any more informations
(I'm sorry about that because I find very important to spend some time
helping maintainers fix things).
Also I know that dmesg output is important for mainteners, so please find
below what I saved before removing the controler. Please also notice that
the output contains many lines related to the fact that I tryed to
force disks back online. I'm sorry about not having the very first error
messages, but they was so much output from indirect troubles that append
after the inititial problem that dmesg beginning was already troncated
when I logged on the machine.
The most significant message is probably:
DAC960#0: Physical Drive 0:x killed because of bad tag returned from drive
but I don't find it meaningfull at all, and since there is no source code
available to scan, that's why I stopped trying to cope with this controler.
Also, if you want to test the controler yourself, I can ask my compagny
to send and give it to you, since we are not going to use it any more.
The above "bad tag" message covers a multitude of sins, sometimes including
drives that become catatonic after a SCSI bus reset.

The firmware in that AcceleRAID controller is quite old. I've had a newer and
much better version on my web page for over a year now. Did you ever update
the firmware in the controller to the version I was providing, or a newer one
from Mylex? Compatibilty issues between the controller and disk drives often
require specific minimum firmware revision levels in both.
