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
To load the driver directly from the local build directory, load the driver in following in order: # insmod qla2xxx_conf.ko or
# insmod qla2xxx.ko or
# insmod qla2300.ko To load the Driver Parameters The Driver parameters are divided into System Parameters and NVRAM Parameters sections. 6.1 NVRAM Parameters The NVRAM features described below are hard-coded in the Driver.

The two major manufacturers of FC HBAs are QLogic and Emulex and the drivers for many HBAs are distributed in-box with the Operating Systems. How To Find Hba Wwn In Linux You can use scsi hot plug/unplug(in the link https://sites.google.com/site/itmyshare/storage/check-and-list-luns-attached-to-hba ), or disconnect Fibre connection with devices then have a host reboot(I don't like this way).Once you are done, remove scsi_tgt, then Default: 32. https://community.hpe.com/t5/System-Administration/How-to-view-the-HBA-cards-in-linux-redhat/td-p/4604915 ISP2532-based 8Gb Fibre Channel to PCI Express HBA [1077:2532] (rev 02) Step-3: Check if the driver modules are installed.
