Hello all people at linux-scsi! I'm writing this report because I've
exhausted my options with this issue and cannot find any viable solution. :(
[1.] One line summary of the problem:
Problem accessing Symbios-NCR 6285-3621 multilun device via Adaptec
2944W (aic7xxx) HBA.
[2.] Full description of the problem/report:
When configuring 2.6.16.13 kernel scsi subsystem with multilun support,
I'm trying to access a Symbios 6285-3621 Array via an Adaptec 2944W HBA
with aic7xxx module. All scsi "virtual devices" are recognized
sdc-sdd-sde-sdf-sdg-sdh-sdi but then when the kernel tries to detect the
partition tables it gets a lot of "Buffer I/O errors".
The same hardware configuration was working on production as our
database servers until last month with Solaris 7 and Informix IDS
without any problem for at least 5 years, solid. We're now in the
process of migration of this servers to Red Hat Enterprise Linux.
The same issue was triggered with RHEL 4 AS stock up-to-date kernel
(2.6.9-34EL).
[3.] Keywords (i.e., modules, networking, kernel):
SCSI. Symbios. NCR. 6285-3621. Adaptec 2944W. aic7xxx. I/O Errors.
Multilun. Red Hat EL 4.
[4.] Kernel version (from /proc/version):
Linux version 2.6.16.13 (root@xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx) (gcc
version 3.4.5 20051201 (Red Hat 3.4.5-2)) #2 SMP Thu May 4 18:35:29 ART 2006
[5.] Output of Oops.. message (if applicable)
Not aplicable.
[6.] A small shell script or example program which triggers the
problem (if possible)
Booting the system triggers the problem.

[7.7.] Other information that might be relevant to the problem
(please look in /proc and include all information that you
think to be relevant):
[X.] Other notes, patches, fixes, workarounds:
No workaround until now.
Please note that I'm willing to test any solution that you want me to.
Patches, other kernel versions, re-compilations, scsi HBA settings, etc.
I'm totally in charge of this hardware and it is 100% available for testing.
Many, many thanks in advance!
