Installing the QLogic Driver Using a Ramdisk Image

The Red Hat Linux kernel 2.2.X does not automatically load the qla2x00 driver

when the system reboots. You can load the qla2x00 driver at boot time using a

ramdisk image. For more information, refer to the Red Hat installation guide.

Perform the following steps to load the qla2x00 driver using a ramdisk image.

1. Add the following line to the file /etc/conf.modules. For example:

alias scsi_hostadapter qla2x00

NOTE: If there are other SCSI host adapters installed on your system and

the scsi_hostadapter alias is used, define a different alias (for

example, scsi_hostadapterN [where N is a number from 1-9]).

2. Build a new ramdisk image that contains the qla2x00.o object file. For

example:

Type the following commands if you are using Red Hat Linux 6.0:

/sbin/mkinitrd /boot/newinitrd-image 2.2.5-15

Type the following commands if you are using Red Hat Linux 6.1:

/sbin/mkinitrd /boot/newinitrd-image 2.2.12-20

Type the following commands if you are using Red Hat Linux 6.2:

/sbin/mkinitrd /boot/newinitrd-image 2.2.14-5.0

/sbin/mkinitrd /boot/newinitrd-image 2.2.14-6.1

NOTE: The 2.2.5-15, 2.2.12-20, 2.2.14-5.0, or 2.2.14-6.1 file is the

subdirectory under /lib/modules/kernel_release where the

qla2x00.o module resides.

3. Modify the /etc/lilo.conf file to load the ramdisk image. Add the following

line anywhere after the bootable kernel label. For example:

initrd=/boot/newinitrd-image

4. Load a new lilo file by running /sbin/lilo.

Building an SMP Kernel

If the Red Hat Linux 6.0 or 6.1 kernel (version 2.2.X) is installed on your system,

perform the procedure in section 8.5.1 to build an SMP kernel. If the Red Hat
