EMC Host Connectivity with QLogic FC and iSCSI HBAs and FCoE CNAs for the Linux Environment
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 host s and incl uding them
in the ramdisk.
