EMC P/N 300-002-803 manual Device reconfiguration procedures for the iSCSI 3.x driver

Additional Notes

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

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

/etc/init.d/iqlremote stop

or

service iqlremote stop

The modprobe command is a wrapper or an extension to the insmod and rmmod commands. 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 may 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 modprobe command automatically loads all of the dependent modules needed in a module stack based on the information in modules.dep.

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's exported symbol table.

The unloading of the module can be accomplished with the modprobe (with the -r switch) command or the rmmod command. These commands are used to unload the loadable modules from the running kernel if they are not in use and if other modules are not dependent upon them.
