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 the following:

  • HFI 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.

  • CableInfoPolicy is set to None:

    <CableInfoPolicy>None</CableInfoPolicy>
