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
Installation instructions for the in kernel QLogic driver for Linux
2.4.x kernel
The section contains the following instructions for enabling the
QLogic driver:
◆ “Enabling the QLogic driver in RHEL 3.0” on page 42
◆ “Enabling the QLogic driver in SLES 8” on page 43
Enabling the QLogic driver in RHEL 3.0
To enable this driver, follow these steps:
1. Ensure that the /etc/modules.conf file references an entry for
each installed QLogic adapter.
For each installed QLogic QLA23xx-series adapter, add an entry:
alias scsi_hostadapterN qla2300
where N is the sequential value of each QLogic adapter installed
in the system, beginning with the number after the last host
adapter number entry in the file. (The first host adapter entry
begins with zero.)
Example:
alias scsi_hostadapter1 qla2300
alias scsi_hostadapter2 qla2300
alias eth0 tg3
options scsi_mod max_scsi_luns=255
scsi_allow_ghost_devices=1
2. Whenever /etc/modules.conf is modified, a new ramdisk should
be created to reflect the changes made. Create a new ramdisk
image to include the newly added references to the QLogic
adapters:
cd /boot
mkinitrd -v initrd-$1.img $1
where $1 is the v2.4.x kernel version currently running.
Example:
mkinitrd -v initrd-2.4.21-27.ELsmp.img 2.4.21-27.ELsmp
3. Reboot the host.es and
