EMC Host Connectivity with QLogic Fibre Channel and iSCSI (HBAs) and (CNAs) for the Linux Environment
Installing and Configuring the Linux Host with the QLogic Driver
options qla2xxx extended_error_logging=1
3. After the modification to the file appropriate for your
distribution, a new ramdisk needs to be created and the host
rebooted.
• For Red Hat distributions, use:
cd /boot
mkinitrd -v initrd-$1.img $1
where $1 is the currently running v2.6.x kernel version.
Example:
cd /boot
mkinitrd -v initrd-2.6.9-22.ELsmp.img
2.6.9-22.ELsmp
• For SuSE distributions, use:
cd /boot
mkinitrd -i initrd-$1 -k vmlinuz-$1
where $1 is the currently running v2.6.x kernel version.
Example:
cd /boot
mkinitrd -i initrd-2.6.5-7.201smp -k
vmlinuz-2.6.5-7.201smp
4. Reboot the host.
Displaying the QLogic v8.x-series driver parameter information via modinfo
The QLogic v8.x-series driver parameters and their definitions may
be viewed by using the
modinfo command. This command may be
used on any Linux kernel module.
Note: EMC does not support the failover functionality of the QLogic driver.
The modinfo command may be run on the qla2300, qla2xxx_conf,
and
qla2xxx modules. However, the parameter information is
reported only by the
qla2xxx module.
An example of the console output displayed when
modinfo is run on
the
qla2300 module is as follows:
[root@l82bi205 ~]# modinfo qla2300
filename:
/lib/modules/2.6.9-22.ELsmp/kernel/drivers/scsi/qla2xxx/qla2300.ko
