22. 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 unloaded again Modprobe uses the modprobe conf file but parameters passed to it using the command line override parameters in the modprobe conf file 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 host bus adapters in your system Load the driver with the following command modprobe lpfc lpfc_lun_ queue _depth 20 Persistent Configuration Method To make the driver parameters persistent across module loads and reboots modify the etc modprobe conf file If driver parameters are modified in etc modprobe conf the driver must be reloaded for the parameters to take effect Also a new ramdisk image is required if you want the changes to take effect in the next boot See Creating a New Ramdisk Image on page 15 to learn how Driver for Linux Configuration Section Page 13 gt G EMULEX The driver parameters are specified in etc modprobe conf via the options command For example the following sets the verbose flag options lpfc lpfc_log_verbose 0xffff If the same option is specified in both the etc modprobe conf and
