I am getting the infamous aacraid: Host adapter abort request error with my new Adaptec RAID Controller under high I/O. I have read several forums, even Adaptecs, that setting the /sys/block/sdX/device/timeout value to 45 will fix this. However I am running Ubuntu Server 12.04 which already has this value at 45 by default. I also tried the next suggestion which was to update my mobo's bios to the latest, which I did.
I am not sure if anyone else has run into this " aacraid: Host adapter abort request" error before even after taking these steps.
This is what I see in my syslog:
kernel: [ 5493.523282] aacraid: Host adapter abort request (4,0,0,0) Jan 6 20:29:15 server kernel: [ 5493.523309] aacraid: Host adapter abort request (4,0,0,0) Jan 6 20:29:15 server kernel: [ 5493.523375] aacraid: Host adapter reset request. SCSI hang ?
Heres my uname -a
