InfiniPath Driver Startup

2 – InfiniPath Cluster Administration Configuration and Startup

You can check and adjust these BIOS settings using the BIOS Setup Utility. For specific instructions on how to do this, follow the hardware documentation that came with your system.

2.4.2

The ib_ipath module provides low level InfiniPath hardware support. It does hardware initialization, handles infinipath-specific memory management, and provides services to other InfiniPath and OpenFabrics modules. It provides the management functions for InfiniPath MPI programs, the ipath_ether ethernet emulation, and general OpenFabrics protocols such as IPoIB, and SDP. It also contains a Subnet Management Agent.

The InfiniPath driver software is generally started at system startup under control of these scripts:

/etc/init.d/infinipath

/etc/sysconfig/infinipath

These scripts are configured by the installation. Debug messages are printed with the function name preceding the message.

The cluster administrator does not normally need to be concerned with the configuration parameters. Assuming that all the InfiniPath and OpenFabrics software 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.

2.4.3

InfiniPath Driver Software Configuration

The ib_ipath driver has several configuration variables which provide for setting reserved buffers for the software, defining events to create trace records, and setting debug level. See the ib_ipath man page for details.

2.4.4

InfiniPath Driver Filesystem

The InfiniPath driver supplies a filesystem for exporting certain binary statistics to user applications. By default, this filesystem is mounted in the /ipathfs directory when the infinipath script is invoked with the "start" option (e.g. at system startup)
