Loading and unloading the Emulex v8.x-series driver

The preceding sections described the process of installing the Emulex

driver, the supported Application Helper Module (lpfcdfc driver),

and the Emulex Application Kit. The Emulex Application Kit and the

Application Helper Module (lpfcdfc driver) utilize the base Emulex

driver functionality. Hence, prior to unloading the Emulex driver, it is

necessary to stop the application kit and to unload the Application

Helper Module (lpfcdfc driver). Also, stop other applications that

maybe using the Emulex driver to access the devices and unmount

any mounted devices.

◆ Run the following commands to stop the Emulex application

daemons:

cd /usr/sbin/hbanyware

./stop-hbanyware

◆ Run the following command to remove the Emulex Application

Helper Module (lpfcdfc driver):

/etc/init.d/elxlpfc stop

◆ Finally, unload the Emulex driver:

modprobe -r lpfc

To reload the Emulex driver, the Application Helper Module (lpfcdfc

driver), and the Application Kit use the following steps.

◆ Load the Emulex driver:

modprobe lpfc lpfc_log_verbose=0x10

◆ Reload the Emulex Application Helper Module (lpfcdfc driver):

/etc/init.d/elxlpfc start
