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
