Normally this information is passed to the driver via the command line, but due to the constraints inherent in using the command line we have provide an alternate method using QLA_OPTS. The following is the procedure to manually add persistent binding commands. Additional Notes 8.1 Failover Support 8.2 Persistent Binding 8.3 Configuration Data 8.4 Booting from SAN 9. IP Support 9.1 Load the Driver Manually using insmod or modprobe Before loading the driver manually, first build the driver binary from the driver source files as described in sections https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Linux/5/html/Online_Storage_Reconfiguration_Guide/fc-native-drivers-capabilities.html

For qlogic, you need to know the model ahead of time and the look for it. Default: 20 seconds qlport_down_retry - This parameter defines how long to wait for a port that returns a PORT-DOWN status before returning I/O back to the OS. How To Check Hba Card Status In Linux Here is how to switch to release mode: cd /root/scst make 2release Now build the SCST kernel modules. Linux Fibre Channel Commands Default: 0 (portname binding) ConfigRequired - This parameter defines how to bind the devices. 0 - Present all the devices discovered to the OS. 1 - Present only the configured devices

On RHEL6/SL6, there is no file called /etc/modprobe.conf, instead there is /etc/modprobe.d/ you can specify your special configuration there, modify the configuration file, or create your own one. news SNIA API Library Package Its distributed (qlapi--rel.tgz) as part of driver combo package qla2xxx-vx.yy.zz-dist.tgz. All appropriate configuration data is written to the _conf.ko module. 8.3.3 Updating Configuration Manually Manually updating the /etc/qla2xxx.conf file is strongly discouraged.
