Obtaining 3ware Linux Drivers

www.3ware.com
Obtain the 3ware driver for Linux from one of these two sources:
•
3ware software CD-ROM
SuSE, and Fedora Core Linux are included on this CD.
• 3ware web site. You can download the latest compiled and tested driver
for supported Linux distributions from the 3ware web site at
http://www.3ware.com/support/index.asp
the Linux driver source, which you can use to compile the latest driver for
RedHat, SuSE, and other similar distributions, running similar kernel
strings.
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.
For Red Hat and SuSE, AMCC offers the following drivers:
• x86 32-bit for Intel x86 and AMD Athlon
• x86_64 64-bit for AMD Opteron and Intel Xeon (EM64T)
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 3DM 2 or the CLI. (For details, see "Viewing
Information About a Controller" on page 86.)
You can also check it using the following method:
If you have a 2.4 kernel or earlier,
cat /proc/scsi/3w-9xxx/*
where the asterisk (*) represents SCSI host ID and
family of the controller. For example:
cat /proc/scsi/3w-9xxx/0
If you have a 2.6 kernel with sysfs, type the following command:
cat /sys/class/scsi_host/
where <hostid> is usually host0, 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
