Updating the 3ware Driver Under Red Hat or
Fedora Core
The following steps describe how to update the 3ware driver under Red Hat.
To update the 3ware driver under Red Hat
1
Download and extract the driver, as described under “Downloading the
Driver and Firmware” on page 165.
2
Backup any critical data prior to updating the 3ware driver.
3
Change the directory to the location with the extracted driver.
4
Copy the files to the appropriate directory.
(In the commands below, replace <version> with the applicable Red Hat
or Fedora Core version, such as ws4_u4 or fc5, and replace <kernel> with
the applicable kernel, for example 2.6.15-x)
Note:
The name of the module you will copy (
3w-9xxx.*
) varies,
depending on the kernel; however you will always copy it to a file named
3w-9xxx.o for 2.4 kernels, or 3w-9xxx.ko for 2.6 kernels
For Red Hat or Fedora Core Uniprocessor
cp
<version>
/3w-9xxx.o /lib/modules/
<kernel>
/drivers/scsi/3w-9xxx.o
For Red Hat SMP
cp
<version>
/3w-9xxx.smp /lib/modules/
<kernel>
/drivers/scsi/3w-9xxx.o
For Red Hat Bigmem
cp
<version>
/3w-9xxx.big /lib/modules/
<kernel>
/drivers/scsi/3w-9xxx.o
For Red Hat Hugemem
cp
<version>
/3w-9xxx.hug /lib/modules/
<kernel>
/drivers/scsi/3w-9xxx.o
Note:
Pre-compiled, tested, and supported drivers are no longer available for older
RedHat or Fedora Core releases using the 2.4 kernel. The source code is still
available (for a limited time) if a newer driver is still needed. Check the release
notes for more details regarding supported operating systems
Backup your original driver before updating in case you need to revert back to it.
However, you will not be able to revert back to the original driver if you are booting
from that unit.
