Installing and Configuring the Linux Host with the QLogic Driver

4.After the modification to /etc/modules.conf has been made, a new ramdisk needs to be created and the host rebooted.

To create a new ramdisk, type the mkinitrd command:

For Red Hat, type:

cd /boot

mkinitrd –v initrd-$1.img $1

where $1 is the v2.4.x kernel version currently running.

Example:

cd /boot

For SuSE, type:

cd /boot

mkinitrd –i initrd-$1-k vmlinuz-$1

where $1 is the v2.4.x kernel version currently running.

Example:

cd /boot

mkinitrd -i initrd-2.4.21-286-smp -k vmlinuz-2.4.21-286-smp

5. Reboot the host.

QLogic v8.x-series driver parameters

The QLogic driver contains a number of parameters that may be modified, such as debug.

!IMPORTANT

EMC does not recommend changing these parameters and defaults should be left as is.

Setting the parameter values

The values of the general driver parameters may be modified at the driver load time. This modification may be performed at the command line or by adding the parameters to the /etc/modprobe.conf file on RHEL 4.0 hosts and the /etc/modprobe.conf.local file on SLES 9 hosts and including them in the ramdisk.
