Q

2 – InfiniPath Cluster Administration Configuration and Startup

6.To verify that the configuration files are correct, you will normally now be able to run the commands:

#ifup eth2

#ifconfig eth2

Note that it may be necessary to reboot the system before the configuration changes will work.

2.4.7

OpenFabrics Configuration and Startup

In the prior InfiniPath 1.3 release the InfiniPath (ipath_core) and OpenFabrics (ib_ipath) modules were separate. In this release there is now one module, ib_ipath, which provides both low level InfiniPath support and management functions for OpenFabrics protocols. The startup script for ib_ipath is installed automatically as part of the software installation, and normally does not need to be changed.

However, the IPoIB network interface and OpenSM components of OpenFabrics can be configured to be on or off. IPoIB is off by default; OpenSM is on by default.

IPoIB and OpenSM configuration is explained in greater detail in the following sections.

NOTE: The following instructions work for FC4, SUSE9.3, SLES 9, and SLES 10.

2.4.7.1

Configuring the IPoIB Network Interface

Instructions are given here to manually configure your OpenFabrics IPoIB network interface. This example assumes that you are using sh or bash as your shell, and that all required InfiniPath and OpenFabrics RPMs are installed, and your startup scripts have been run, either manually or at system boot.

For this example, we assume that your IPoIB network is 10.1.17.0 (one of the networks reserved for private use, and thus not routable on the internet), with a /8 host portion, and therefore requires that the netmask be specified.

This example assumes that no hosts files exist, and that the host being configured has the IP address 10.1.17.3, and that DHCP is not being used.

NOTE: We supply instructions only for this static IP address case. Configuration methods for using DHCP will be supplied in a later release.

Type the following commands (as root):

# ifconfig ib0 10.1.17.3 netmask 0xffffff00
