QLogic v7.x and v8.x series driver parameters
77
Installing and Configuring the Linux Host with the QLogic Driver
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.
Note: When attaching to CLARiiON and 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:
