5 – Red Hat Linux Driver Installation

Installing the Driver

5-6 PRELIMINARY IS0053302-00 7

5.3.5

Building a Custom Kernel with the QLogic Driver

Should this section be in the manual? This is new to me. Also, how do these

instructions fit with the rest of this section? Is this procedure instead of, or in addition

to, building a UP or SMP version of the driver?

Since it is not feasible to construct a single set of kernel build instructions for every

possible hardware or software configuration, this section provides an example of

how to compile the driver into the Linux kernel. You may have to make some

adjustments in the procedure for your particular system hardware or software

configuration.

This process is only supported in Red Hat versions 8, 9, and Advanced Server 2.1.

In the following sections, the kernel source tree is referenced as /usr/src/linux. Under

the Red Hat distribution, the normal directory path is /usr/src/linux-2.4.

5.3.5.1

Prerequisites

Verify that both kernel-headers and kernel-source RPMS are already installed by

typing the following:

# rpm -qa | grep kernel

If the kernel-headers and kernel-source RPMs are not installed, install them from

the distribution CD by typing:

# rpm -i kernel-source* (Not required for Red Hat 9.)

# rpm -i kernel-headers* (Not required for Red Hat 9.)

5.3.5.2

Building a Custom Kernel to Load the Driver

The following instructions provide an example of how to build a custom kern to load

the driver.

1. Create a directory under kernel source tree. Using the driver disk created in

section 5.2, copy the qla4xxxsrc-vx.xx.tgz file to the directory and extract the

files. For example:

# mkdir /usr/src/linux/drivers/scsi/qla4xxx/

# cd /usr/src/linux/drivers/scsi/qla4xxx/

# mcopy a:*.tgz . (The period (.) at the end is required.)

# tar -xvzf *.tgz

# rm -f Makefile

# cp -f Makefile.kernel Makefile

2. Edit the Makefile under the kernel scsi directory. For example:

# cd /usr/src/linux/drivers/scsi

# vi Makefile
