Normally, this configuration file is set up correctly at installation and the drivers are 
loaded automatically during system boot once the RPMs have been installed. 
However, the ib_ipath driver has several configuration variables that set 

reserved buffers for the software, define events to create trace records, and set 
the debug level. 

If you are upgrading, your existing configuration files will not be overwritten.

The device files are:

/dev/ipath 
/dev/ipath0, /dev/ipath1, ... 

The numbered device files allow access to a specific InfiniPath unit. 

See the ib_ipath man page for more details.

Use the following commands to check or configure the state. These methods will 
not reboot the system. 

To check the configuration state, use this command. You do not need to be a root 
user:

To enable the driver, use the following command (as a root user):

To disable the driver on the next system boot, use the following command (as a 
root user):

Restart the software if you install a new InfiniPath release, change driver options, 
or do manual testing. 

You can start, stop, or restart (as a root user) InfiniPath support with:

# /etc/init.d/openibd [start | stop | restart]

This command does not stop and unload the driver if the driver is already 
loaded.
