As in a Debian 5.0.3 (Lenny) standard installation the driver for DELL
SAS HBA seems to be outdated
I like to have I my production environment a newer version.
[ 0.000000] Linux version 2.6.26-2-amd64 (Debian 2.6.26-19lenny2)
(da...@debian.org)
(gcc version 4.1.3 20080704 (prerelease) (Debian 4.1.2-25))
#1 SMP Thu Nov 5 02:23:12 UTC 2009
05:00.0 SCSI storage controller: LSI Logic / Symbios Logic SAS1068E
PCI-Express Fusion-MPT SAS (rev 08)
Subsystem: Dell SAS 6/iR Adapter RAID Controller
...
Kernel driver in use: mptsas
Kernel modules: mptsas
Also in some newer kernel versions like 2.6.29.x, 2.6.30.x and so on are
only
[ 1.165426] Fusion MPT base driver 3.04.06

LSI provide a actual DKMS package. Related to DKMS you will find some
more infos on
http://linux.dell.com/projects.shtml
http://linux.dell.com/dkms/
http://en.wikipedia.org/wiki/Dynamic_Kernel_Module_Support
I prepared my system to build kernel modules
# aptitude install module-assistant rpm alien fakeroot
# m-a prepare
I downloaded the latest source package from LSI
but I think it is possible to use the package from DELL download page
too
http://www.lsi.com/DistributionSystem/AssetDocument/MPTLINUX_RHEL5_SLES1
0_PH16-4.18.00.00-1.zip
As this is a 150MB package for different platforms I extracted from
subfolder
/MPTLINUX_RHEL5_SLES10_PH16-4.18.00.00-1.zip/mptlinux_RHEL5_SLES10_rel/R
HEL5_SLES10.tar.gz/RHEL5_SLES10.tar/dkms-1/mptlinux-4.18.00.00-1.dkms.ta
r.gz/mptlinux-4.18.00.00-1.dkms.tar
the two neccessary files
dkms-2.0.19.1-1.noarch.rpm
mptlinux-4.18.00.00-1dkms.noarch.rpm
Of course there would be a newer version of DKMS but this depends on
upstart-job
which is part of http://packages.debian.org/search?keywords=upstart
itself.
So in this kernel version I think this will be not necessary yet.
Sometimes I prefare to have deb packets so I used DKMS in this way
# alien dkms-2.0.19.1-1.noarch.rpm
# dpkg -i dkms-2.0.19.1-1.noarch.deb
and installed the driver sources than
# rpm -i mptlinux-4.18.00.00-1dkms.noarch.rpm --nodeps
and build for your system
# dkms status
#dkms mkdeb -m mptlinux -v 4.18.00.00
# dkms status
mptlinux, 4.18.00.00, 2.6.26-2-amd64, x86_64: installed (original_module
exists)</code>
# reboot
And my DELL SAS HBA Version 5 or 6 is working.
# modprobe mptsas
# modinfo mptsas
filename: /lib/modules/2.6.26-2-amd64/kernel/drivers/message/fusion/mpt
version: 4.18.00.00
...
# lsmod | grep mpt
