Obtaining 3ware Linux Drivers

Obtain the 3ware driver for Linux from one of these two sources:

3ware CD

. Compiled and tested drivers for Red Hat, openSUSE, SUSE

Linux Enterprise Server (SLES), and Fedora Core Linux are included on
this CD. Also included are the 3ware driver sources to compile kernel-
specific drivers for many other Linux distributions.

LSI web site.

You can download the latest compiled and tested driver for

supported Linux distributions from the LSI web site at

http://www.lsi.com/channel/ChannelDownloads

. Also included are the

3ware driver sources to compile kernel specific drivers for many other
Linux distributions.

Determining the Current Version of your 3ware Driver

If you already have a 3ware controller installed, you can check the current
driver version, using either 3DM2 or the CLI. (For details, see “Viewing
Information About a Controller” on page 65
.)

You can also check it using the following method:

If you have a 2.6 kernel with sysfs, type the following command:

cat /sys/class/scsi_host/

/3ware_stats

where is usually host 0, unless other SCSI devices are available,
in which case it may be host1 or higher.

If you have a 2.6 kernel without sysfs, type the following command:

dmesg | grep 3w

Warning:

Be sure to use the correct driver for your processor. It is possible to load

the wrong driver onto a system, however when you boot such systems, they will not
work.

LSI offers the following drivers for various Linux distributions:

32-bit for Intel x86 and AMD Athlon

64-bit for AMD Opteron and Intel Xeon (EM64T)
