Building a Ramdisk Image to Load the Driver Automatically

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.For Red Hat Linux 6.2, add the following line to the file /etc/conf.modules. For Red Hat Linux 7.0, 7.1, and 7.2, add the following line to the file /etc/modules.conf. For example:

alias scsi_hostadapter qla2x00

NOTE: If there are other SCSI HBAs 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.Copy the object file to:

/lib/modules/<kernel release version>/scsi (Red Hat Linux 6.2 or 7.0)

/lib/modules/<kernel release version>/drivers/scsi (Red Hat Linux 7.1 and 7.2)

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

For a single-processor system, type the following commands, where x.x.xx–x.xis the Red Hat Linux version number:

/sbin/mkinitrd /boot/newinitrd-image x.x.xx-x.x

For a multiprocessor system, type the following commands, where x.x.xx–x.xis the Red Hat Linux version number:

/sbin/mkinitrd /boot/newinitrd-image x.x.xx-x.xsmp

4.Modify the /etc/lilo.conf file to load the new ramdisk image. In the following examples, .x.xx–x.xis the Red Hat Linux version number.

For a single-processor system, change the following line from:

initrd=/boot/initrd-x.x.xx-x.x.img

to:

initrd=/boot/initrd-image

For a multiprocessor system, change the following line from:

initrd=/boot/initrd-x.x.xx-x.x.smp.img

to:

initrd=/boot/initrd-image
