Two post-installation tasks are required:
Install the kernel source tree
Update the QLA2400 driver
21.6.1 Install the kernel source tree
Once RHEL4 is installed and running, we need to install the kernel source. We obtain the
kernel source RPM file (for example, from Red Hat Network -
https://rhn.redhat.com
). For
our particular kernel version, the filename is
kernel-2.6.9-34.EL.src.rpm
.
Install the kernel source by following these steps:
1. Install the source RPM with the following command:
rpm -Uvh kernel-2.6.9-34.EL.src.rpm
2. Change to the following directory:
cd /usr/src/redhat/SPECS
3. Build the kernel source tree with this command:
rpmbuild -bp kernel-2.6.spec --target=i686
4. The kernel source tree is now in the following directory:
/usr/src/redhat/BUILD/kernel-2.6.9/linux-2.6.9
21.6.2 Update the QLA2400 driver
As stated, the RHEL4 installation CDs include the QLA2400 driver, but not the latest version.
So we need to update the driver from version 8.01.02 to the latest (at the time of writing, this
is v8.01.06).
We download the QL2400 driver v8.01.06 from QLogic Web site (linked from IBM Systems
support Web site):
http://support.qlogic.com/support/oem_detail_all.asp?oemid=376
The filename is ibm_dd_ds4kfc_8.01.06_linux2.6_anycpu.tgz.
To update the driver, follow the process below.
1. Extract the contents from the driver file:
tar -xvzf ibm_dd_ds4kfc_8.01.06_linux2.6_anycpu.tgz
This will create subdirectory qlogic and put the driver files in it.
2. Change to subdirectory qlogic and extract the driver source files by executing
drvrsetup
:
cd qlogic
./drvrsetup
3. Use the command
libinstall
to set up the SNIA API library:
./libinstall
4. Run the script build.sh with parameter install. This will build and install the driver module
files.
cd qla2xxx-8.01.06
./extras/build.sh install
