Carroll -
Sure, I've cced -stable.
I am actually using the card on a 66mhz bus (no riser card), and I just noticed the Knowledge Base article before you mailed me back. The PDF link you posted is broken.
Is an RMA necessary in my case? It appears they are providing a firmware upgrade that's supposed to take care of the problem (and my firmware is older). Installing that is my next step.

I noticed your postings re your RAID with Maxtor disks.
I'm having similar issues, with a 8506-4LP + 4 Maxtor DiamondMax 9 160GBs. Basically I've been getting some kind of drive error that typically leads to the system hanging, and causes the RAID to be degraded upon reboot. Most of the time I've been able to rebuild and continue on.
If you are using it in a 66 mhz slot, that is probably your problem right
there. If you are using riser cards, and the controller card was purchased
before Q1 2004, then you need to buy a new riser card. There is a physical
bug with the card handling 66 mhz properly. Even if you directly connect to
the system, you can run into issues if the system mobo supports 66 mhz. I
believe they will accommodate RMAs in this case.

Now, if none of that appiles to you, then the problem continues

Scroll to the last message.
Implicitly they are saying that a lot of CRC errors can cause the drive to
"drop a drive" from the array. In my case, I am using an older ATA
backplane which only supports ATA/33... I am suspecting the CRC errors are
related to my backplane. I am getting it swapped out tomorrow, so hopefully
that will resolve that issue. If not, I have to keep replacing parts...
such as my controller card itself and/or the riser card (even though I am
not affected by the 66 mhz issue). I do get random harddisk dropping out of
my array. I am suspecting that if my controller gets one of these major
drop outs during operation, it probably can result in a hard hang. Bad
cables can cause this problem as well.
Random loss of power to the disk might cause it to drop out of the array as
well.
What's the latest you've found on this issue?
I noticed you were playing with the smart monitoring tools, have they
shed any light on the subject? I'm planning to try them but this RAID
has been down for about a half day now (at this point I'm not sure if a
drive is dead or what, I seem to be getting errors on 2 different
drives now).
Smartctl helped me pre-emptively remove some disks that was failing,
however, that was not the problem. Even after removing one bad disk and
rebuilding the array, I still ran into the same problems.
Have you contacted 3ware at all about the problem?
I have recently contacted 3ware by emailing the results from the 3Ware cli
program. If your 3dmd or 3dmd2 supports it, go to the 'alarms' section and
download the extended errorlog file and send it off to them. If you do not
have this feature or all you see is /var/log/messages kind of output then do
this.
(do something like) ./tw_cli info c0 errorlog
and copy that output to a file. Also send them a copy of 3dmd's technical
page.
Write down some simple steps on what you did and how to repeat the problem
if possible.
Then email it off to [EMAIL PROTECTED]
Thanks,
