Re: 3ware 9550 using 3w-9xxx driver lockups ?

Looks to me like you have a bad drive (or several bad drives, if
other drives on other machines are reallocating sectors as well).

Many reallocated sectors could be a sign that your drive is about to die...
Are you booting off this disk?

Have you run smartmontools on those bad disks?

You fail to mention your raid configuration.

Are you running the latest 3ware firmware for that controller? There
is a Linux specific userspace firmware update utility.

Also, this topic is better served on the linux-scsi email list.

Hi,

One of our servers locked up (no kernel panic, but no response to
console/network) with the following output on console :

I'd put this down to bad hardware until an identically spec'd machine
(with fresh disks) did the same thing.


Anyone else noticed any issues using the newer 3-ware 9550S cards with
the 3w-9xxx driver ?

Adam,

Have him check the cables as well unless he using the multi-lane controller. I see this a lot with loose ATA cables
on units, but since we moved over to the multi-lane architecture -- great work on the multi-lane version of the adapters, BTW.
He should also check is he's getting -2 bio errors. I see -2 bio errors in parallel with this if its a bad cable.
