Installing and Configuring the Linux Host with the QLogic Driver
Note: When attaching to VNX series, CLARiiON, or Symmetrix storage
arrays, EMC recommends that the ConfigRequired and ql2xfailover
parameters be set to zero in the /etc/modules.conf file.
◆ To load the QLogic driver onto the system with the parameters at
the command line, use:
modprobe qla2300 extended_error_logging=1
◆ In order for the modular driver to be loaded at boot time with
these parameters set to 0, a separate options line needs to be
added to the
/etc/modprobe.conf file on RHEL 4.0 hosts and the
/etc/modprobe.conf.local file on SLES 9 hosts.
1. Edit the file appropriate for the distribution being used.
• For Red Hat distributions, edit:
vi /etc/modprobe.conf
• For SuSE distributions, edit:
vi /etc/modprobe.conf.local
2. Add the options line for the appropriate driver settings.
options qla2xxx extended_error_logging=1
For example, the /etc/modprobe.conf file on RHEL 4.0 might
look as follows:
alias eth0 tg3
alias eth1 tg3
alias scsi_hostadapter megaraid_mbox
alias scsi_hostadapter2 qla2xxx
alias scsi_hostadapter3 qla2xxx_conf
alias scsi_hostadapter4 qla2300
options qla2xxx extended_error_logging=1
And the /etc/modprobe.conf.local file on SLES 9 might look
as follows:
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-
