Resolving conflictswith the IMM LAN over USB interface

Use this information to resolve LAN over USB conflicts withnetwork configurations and applications.

There are several actions that resolve LAN over USBconflicts with network configurations and applications:

For conflicts with Open MPI, configure the application     so it does not attempt to use this interface.Take the interface down (run ifdown under Linux).Remove the driver (run rmmod under Linux).Disable the USB in-band interface on the IMM through     either the IMM Web interface or the AMM Web interface.

Important: If you disable the USB in-band interface, you cannot perform an in-band update ofthe IMM firmware using the Linux or Windows flash utilities. If the USB in-band interface is disabled, use the Firmware Updateoption on the IMM Web interface to update the firmware.

If you disable the USB in-band interface,also disable the watchdog timeouts to prevent the server from restartingunexpectedly.

Use the following steps      to disable the LAN over USB interface from the IMM Web interface.Log in to the IMM on       which you want to disable the USB device driver interface.In the navigation       pane, click System       Settings and scroll down to the Miscellaneous       area.Select the Do not allow commands on USB       interface check box to disable the USB in-band       interface. Selecting this option does not affect the USB remote presence       functions (for example, keyboard, mouse, and mass storage). When you       disable the USB in-band interface, the in-band systems-management       applications such as the Advanced Settings Utility (ASU) and firmware       update package utilities might not work.

Note: The ASU works with adisabled USB in-band interface if an IPMI device driver is installed.

If you try to use systems-management applicationswhile the in-band interface is disabled, they might not work.

Click Save.Use the following steps      to disable the LAN over USB interface from the Advanced Management Module      (AMM) Web interface: Log in to the AMM Web       interface. In the navigation       pane, click Blade       Configuration under the Blade Tasks heading.Scroll down to the       Service Processor LAN over USB interface are on the Blade Configuration       web page. The section lists all blades in the chassis which are capable       of enabling and disabling the LAN over USB interface.Select the check boxes       next to the blade or blades that you want to enable or disable. Click the Disable button       to disable the LAN over USB interface on the selected blades.
