Potential conflicts with the LAN over USB interface

In some situations, the IMM2 LAN over USB interface can conflict with certain
network configurations, applications, or both. For example, Open MPI attempts to
use all of the available network interfaces on a server. Open MPI detects the IMM2
LAN over USB interface and attempts to use it to communicate with other systems
in a clustered environment. The LAN over USB interface is an internal interface, so
this interface does not work for external communications with other systems in the
cluster.

Resolving conflicts with the IMM2 LAN over USB interface

There are several actions that resolve LAN over USB conflicts with network
configurations and applications:
v For conflicts with Open MPI, configure the application so that it does not attempt
v Take the interface down (run ifdown under Linux).
v Remove the device driver (run rmmod under Linux).

Configuring the LAN over USB interface manually

For the IMM2 to use the LAN over USB interface, you might have to complete other
configuration tasks if the automatic setup fails or if you prefer to set up the LAN
over USB manually. The firmware update package or Advanced Settings Utility
attempts to perform the setup automatically. For more information about LAN over
USB configuration on different operating systems, see the IBM white paper
Transitioning to UEFI and IMM on the IBM website.

Installing device drivers

For the IMM2 to use the LAN over USB interface, you might have to install
operating-system drivers. If the automatic setup fails or if you prefer to set up the
LAN over USB manually, use one of the following procedures. For more information
about LAN over USB configuration on different operating systems, see the IBM
white paper Transitioning to UEFI and IMM on the IBM website.
Installing the Windows IPMI device driver
The Microsoft IPMI device driver is not installed by default on Microsoft Windows
Server 2003 R2 operating systems. To install the Microsoft IPMI device driver,
complete the following steps:
1. From the Windows desktop, clickStart → Control Panel → Add or Remove
2.
3.
4. Select Hardware Management.
5. Click Next. The installation wizard opens and guides you through the
Note: The Windows installation CD might be required.
Installing the LAN over USB Windows device driver
When you install Windows, an unknown RNDIS device is shown in the Device
Manager. You must install a Windows INF file that identifies this device and is
required by Windows operating system to detect and use the LAN over USB
functionality. The signed version of the INF is included in all of the Windows
to use the interface.
