help decoding aacraid errors (3.10.40 kernel)

help decoding aacraid errors (3.10.40 kernel)

[Arkadiusz Miskiewicz]

Hello.

I'm using 3.10.40 kernel with adaptec 3405 and unfortunately I'm getting I/O 
errors and dmesg errors like below. Is there a howto how to decode these 
errors or what these actually mean?

Some details, including full dmesg output at
http://ixion.pld-linux.org/~arekm/p2/web3-adaptec-problem/
eg
http://ixion.pld-linux.org/~arekm/p2/web3-adaptec-problem/dmesg.txt

That doesn't seem to be hard disk error (at least I don't see any bad errors 
from arcconf tool).

0x4 is "hardware error".

0x44/0x00 is "internal target failure".

Thanks for links. I wonder why kernel doesn't decode these to be actually 
readable without a need for asking on ml - was decoding considered?

Anyway Adaptec support helped with details:

http://ask.adaptec.com/app/answers/detail/a_id/14947/track/AvOF~QqxDv8S~TbvGmIW~yLb_fsq5C75Mv~s~zj~PP8l

Basically this controller finds "bad stripes" and blocks any access to these 
areas resulting in errors :-/ What's more interesting there is no recovery 
procedure beside recreation. Fun :-)

Normally it does; I was a bit surprised to see numbers printed with such
a recent kernel.

Sense key decoding to text has been around almost forever (the 'snstext'
table of sense strings pre-dates git, i.e. 2.6.12ish).

Is it possible your kernel was built without CONFIG_SCSI_CONSTANTS?

Bryn.

Bingo! Thanks for your help.
