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.
