Emulex Driver for Linux

1. Note The Linux 2 6 kernel only supports setting the log_verbose nodev_tmo and use_adisk driver parameters for individual HBAs You must apply other driver parameters to all HBAs contained in the host Driver Configuration Methods using modprobe and etc modprobe conf The following sections describe how to set driver parameters using the modprobe command and by manually editing etc modprobe conf Note Emulex recommends using the HBAnyware utility or the hbacmd utility to change parameters See the HBAnyware 4 0 User Manual for more information Temporary Configuration Method When you manually load the driver as a module using the modprobe command and change one or more driver parameter values it is a temporary configuration These changes are considered temporary because they are valid for the current session only or until the driver is manually loaded again Using the insmod command requires no editing or saving This temporary configuration method overrides the modprobe conf file for the current session Values can be expressed in hexadecimal or decimal notation Example of Temporary Configuration You want to temporarily set lun_queue_depth to 20 default is 30 for all HBAs in your system Load the driver with the following command modprobe lpfc lpfc lun queue depth 20 Note You cannot override parameters set in modprobe conf Persistent Configuration Method To make the driver parameters persistent acr
