Hello, I hope I can get a little help from you regarding this kind of 
crash !

Hardware:
- server, TYAN Tempest i5000VS S5372 BIOS v1.0.4
- 8 SATA drives Seagate 136 Gb attached on a AIC-9410 controller
- one IDE (boot disk and system)
- 8 Gb RAM

Software:
- OpenSUSE 10.2 x86_64 (tried also with SLES 10 but didn't succed in 
compiling adp94xx driver from Adaptec)

Kernels: i tried with any  of them : linux-2.6.20.1 ,  linux-2.6.20.4 ,  
linux-2.6.20.7 , linux-2.6.21.rc7
The last one has the 1.0.3 version of aic94xx driver but the results are 
the same :-(

Description:
- the server is running a very heavy loaded PostgreSQL database with 
tables spread on those SAS drives, a lot of writes and reads
- at least 4, 5 times a day I got some warnings in /var/log/messages 
(sas: Enter sas_scsi_recover_host , trying to find task XXX ---> 
aic94xx: came back from clear nexus) but the system is still working
- more rarely (once per day) I got the following bug in 
/var/log/messages and the system is crashed, SAS drivers are not working 
anymore, shutdown command is waiting forever, need to hardware reset the 
system

I tried to fetch and compile the 
Adaptec_adp94xx-OpenBuild-B11662.i386.rpm driver from adaptec but got a 
lot of stupid compile errors.
Is there anything that I can do in order to make it work ? Would you 
need more information that could help you understand the problem?
Please Cc: me at    brailateo@flex.ro

Big , BIG, BIG thanks in advance !

This configuration doesn't work on the vanilla linux kernel ... you need
the scsi-aic94xxx-sas-2.6 tree as well for this; is that what you're
running with?

Are these SAS or SATA drives?

Having said that, I still support the original version
of the aic94xx and the SAS stack, which now includes
SAT-1 conformant SATL.

It has allowed some people to upgrade their kernels to
the latest kernel version (as in from git repo), and reported that
it is more stable (i.e. working as opposed to not, including
supporting SATA devices in SAS domains) than the in-kernel version.

It also keeps the sequencer fw together with the driver source
code, so the end-user wouldn't have to mix and match fw version
with driver (kernel) version.

So ... the latest news , from this night ! :-D


So : I got the Adaptec SAS Sequencer Firmware v30 for Open-Source 
AIC94xx Driver included with Linux kernel 2.6.19 and above from the web 
page above.
I use a 2.6.21-RC7 kernel with AIC94xx version 1.0.3 compiled on 
OpenSUSE 10.2 x86_64

Everything went OK, he discovered the disks

I started the stress tests (a lot of writes and read from the SAS disks) 
and after running 8 hours I got the error:

and the machine  became unusable (can't shutdown it)

I have tried also an updated driver based on Adaptec SAS HostRAID SHIM 
package v1.4.11662 ,( on the same page of Adaptec) , send to me by 
Alexander Lavrinenko , compiled for OpenSUSE 10.2 x86_64.
I configured those 8 SAS disks in 2 arrays-10 and tried it.
The linux kerned did saw the arrays as /dev/sda and /dev/sdb
Started the tests ... after 2 hours I got the same type of errors .... 
didn't have the time to wait for general machine freeze  :-D

So ... should I ask for other controller quotation ?
Could you recommend me a good SAS controller, with 8 internal ports, 
supporting Linux , with 99.9999% reliability ? :-)

I have the following options : Intel® RAID Controller SRCSAS18E 
(Parowan)  and   LSI MegaRAID SAS 8408E

so ... your bet ? :-)

Best regards,
Teo

I don't know anything about either of those controllers, though the LSI
1068E has worked quite reliably for me.  I decline to make any
statements about 99.9999% reliability, however.

On the odd chance you still have this controller (and have the time to
test out patches), would you mind applying this patch:

http://sweaglesw.net/~djwong/docs/17-aic94xx-hwi-bugon_1.patch

and reporting back to me what happens?
