Resolving conflicts with the IMM LAN over USB interface
Use any of the following actions to resolve LAN over USB conflicts with network configurations and
applications.
• For conflicts with Open MPI, configure the application so that it does not attempt to use this interface.
• Take down the interface (run iiffd do ow wn n under Linux).
• Remove the device driver (run rrm mm mo od d under Linux).
• Disable the LAN over USB interface from the advanced management module web interface:
1. Log in to the AMM web interface.
2. In the navigation pane, click Blade Configuration under the Blade Tasks heading.
3. Scroll down to the Service Processor LAN over USB interface on the Blade Configuration web page.
The section lists all blades in the chassis that can enable or disable the LAN over USB interface.
4. Select the check boxes next to the blade servers that you want to enable or disable.
5. Click Disable to disable the LAN over USB interface on the selected blade servers.
Configuring the LAN over USB interface manually
An IMM must be configured to use the LAN over USB interface. The firmware update package or Advanced
Settings Utility attempt to perform the setup automatically, if needed. If the automatic setup fails or if you
prefer to set up the LAN over USB manually, use one of the following processes.
For more information about LAN over USB configuration on different operating systems, see the IBM white
paper
Transitioning to UEFI and IMM at “” on page .
Installing the LAN over USB Windows device driver
When you install a Windows operating system, there will be an unknown RNDIS device in the Device
Manager. IBM provides a Windows INF file that identifies this device. The signed version of the INF file is
included in all of the Windows versions of the IMM, UEFI, and DSA update packages. Complete the following
steps to install
ibm_rndis_server_os.inf
.
Note: You only have to perform these steps if the server is running a Windows operating system and the
ibm_
rndis_server_os.inf
file has not been previously installed. The file only has to be installed once. It is required
by Windows operating systems to detect and use the LAN over USB functionality.
1. Obtain a Windows version of the server UEFI code package (see “Updating firmware and device drivers”
on page 30 for more information).
2. Extract the
ibm_rndis_server_os.inf
and
device.cat
files from the firmware update package and copy
them to the
\WINDOWS\inf
subdirectory.
Note: You can use the -x path command-line interface option to extract the files. For more information
about this option, see the readme file that comes with the update package.
3. (Windows 2003) Install the
ibm_rndis_server_os.inf
file by right-clicking the file and clicking Install . This
generates a PNF file of the same name in
\WINDOWS\inf
. (Windows 2008) Click Computer Management ,
then Device Manager and find the RNDIS Device. Click Properties > Driver > Reinstall driver . Point
the server to the
\Windows\inf
directory where it can find the
ibm_rndis_server_os.inf
file and install the
device.
4. Click Computer Management then Device Manager . Right-click Network adapters and select Scan
for hardware changes . A small pop-up confirms that the Ethernet device is found and installed. The
New Hardware Wizard starts automatically.
5. When you are prompted
Can Windows connect to Windows Update to search for software?
, select No, not
this time . Click Next to continue.
