3.8
Configuring the InfiniPath Drivers
This section provides information on InfiniPath driver configuration.
3.8.1
Configuring the
ib_ipath
Driver
The primary configuration file for the
ib_ipath
driver,
ipath_ether
Ethernet
driver, and other modules and associated daemons is:
/etc/sysconfig/infinipath
Normally this configuration file is set up correctly at installation and the driver(s) are
loaded automatically during system boot once the RPMs have been installed.
Assuming that all the InfiniPath and OpenFabrics sofware has been installed, the
default settings upon startup will be:
■
InfiniPath
ib_ipath
is enabled
■
InfiniPath
ipath_ether
is not running until configured
■
OpenFabrics IPoIB is not running until configured
■
OpenSM is enabled on startup. Disable it on all nodes except where it will be
used as subnet manager.
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.
Specific additional instructions for enabling different drivers and modifying
behaviors are presented in the following sections.
3.8.2
Configuring the
ipath_ether
Network Interface
These instructions are for enabling TCP-IP networking over the InfiniPath link. To
enable IPoIB networking,
You must create a network device configuration file for the layered Ethernet device
on the InfiniPath adapter. This configuration file will resemble the configuration files
for the other Ethernet devices on the nodes. Two slightly different procedures are
given below for the ipath configuration; one for Fedora and one for SUSE or SLES
10.
Many of the entries that are used in the configuration directions below are explained
in the file
sysconfig.txt
. To familiarize yourself with these, please see:
