Installing the Driver

12-8 FC2354601-00 E

For Redhat distributions 7.2 with kernel 2.4.9-21 and above, type the following to

rename the old driver binary included in the original distribution, ensuring that it will

not interfere with the updated version:

# cd /lib/modules/<kernel_version>/drivers/addon/qla2300

# mv qla2300.o qla2300_rh.o

After renaming the older version of the drivers, you can load the new driver using

modprobe after updating the modules dependency file.

12.3.2.4

Building a RAMDISK Image to Load the Driver Automatically

You can load the qla2xxx driver at boot time using a RAMDISK image. For more

information, refer to the Red Hat installation guide.

Before building a RAMDISK image, you must build a UP or SMP version of the

driver, as described in section 12.3.2.1 or 12.3.2.2.

Perform the following steps to load the qla2xxx driver using a RAMDISK image:

1. Copy the files to /lib/modules/<kernel version>/kernel/drivers/scsi/ by typing:

# make install

For Redhat distributions 7.2 with kernel 2.4.9-21 and above, type the following

to rename the old driver binary included in the original distribution, ensuring

that it will not interfere with the updated version:

# cd /lib/modules/<kernel_version>/drivers/addon/qla2300

# mv qla2300.o qla2300_rh.o

2. Add the following line to /etc/modules.conf:

alias scsi_hostadapter0 qla2300

3. Type the following command to build the RAMDISK image that contains the

qla2300.o module:

# mkinitrd -f <RAMDISK image file name> <kernel version>

For example:

# mkinitrd -f /boot/newinitrd-image.img 2.4.7-10

# mkinitrd -f /boot/newinitrd-image.img 2.4.7-10smp

NOTE: To obtain your kernel version before using the above command, type:

# uname -r

Copy the file to /boot.
