Obtaining 3ware Linux Drivers
Obtain the 3ware driver for Linux from one of these two sources:
• 3ware software CD-ROM . Compiled and tested drivers for Red Hat,
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 . Included in these downloads is
the Linux driver source, which you can use to compile the latest driver for
RedHat, SuSE, and other similar distributions, running similar kernel
strings.
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, type the following command:
cat /proc/scsi/3w-9xxx/*
where the asterisk (*) represents SCSI host ID and 9xxx represents the
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/ <hostid> /stats
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
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)
