3.5.1. Starting the Fabric Manager

This section provides instructions for starting the Fabric Manager.

Important

The Fabric Manager is always run from a node connected to the latest generation switch (for example, a CN5000 switch).

3.5.1.1. Prerequisites

Prior to starting the Fabric Manager, you must edit the opafm.xml file (located under /etc/opa-fm/) and ensure HFI1 2 is enabled for fm1.

<Start>1</Start>  <-- 1 signifies enabled
<Name>fm1</Name> 
<Hfi>2</Hfi> 
<Port>1</Port>

Prior to starting the Fabric Manager, you must edit the opafm.xml file (located under /etc/opa-fm/) and ensure the correct HFI1 port is enabled.

Note

You must know whether your Fabric Manager SuperNIC is a Version I or Version II board to correctly set fm0. Refer to Replace the SuperNIC, Prerequisites.

  • For Version I boards, HFI1 1, port 2 is enabled for fm0:

    <Start>1</Start>  <-- 1 signifies enabled
<Name>fm0</Name> 
<Hfi>1</Hfi> 
<Port>2</Port>

    Note

    Also note that a single port SuperNIC appears as dual port in opainfo output.

  • For Version II boards, HFI1 1, port 1 is enabled for fm0:

    <Start>1</Start>  <-- 1 signifies enabled
<Name>fm0</Name> 
<Hfi>1</Hfi> 
<Port>1</Port>
