Additional Notes

If PowerPath is installed and enabled on the host, then the PowerPath service must be stopped.

To stop the PowerPath service, issue one of the two following commands:

/etc/init.d/PowerPath stop or

service PowerPath stop

If the QLogic SANsurfer daemon qlremote is installed and enabled on the host, then the qlremote service must be stopped in order for the driver to be removed from the currently running kernel.

To stop the qlremote service, issue one of the two following commands:

/etc/init.d/qlremote stop

or

service qlremote stop

The modprobe command is a wrapper or an extension to insmod and rmmod. The modprobe command uses and maintains a set of files that describe all the modules that are available for the current kernel in /lib/modules.

The modprobe command can be used to load and unload an entire set of modules. (A set of modules can be a single module or a stack of dependent modules.) The command automatically loads all of the modules needed in a module stack based on the information in modules.dep.

Note: EMC recommends using modprobe to load and unload the QLogic modular driver.

The loading of the module is accomplished with either modprobe or insmod. These commands are used to install loadable kernel modules into a running kernel. The commands will attempt to link a module into the running kernel by resolving the symbols from the kernel exported symbol table.

The unloading of the module can be accomplished with the modprobe (with the -rswitch) command or the rmmod command. These commands are used to unload the loadable modules from the
