4.4.5. Configuring More Rails

As your network grows, you may want to add more rails.

4.4.5.1. Procedures

To configure additional rails on the same Fabric Manager to the same or different subnets, perform the following steps:

  1. Set up the first two SuperNICs (fm0 and fm1) as described in Configuring Dual Rails for Dual Subnets.

  2. Copy the <Shared> element for fm1 and paste it after the closing element, </Shared>.

    <Shared>
  <Start>0</Start> <!-- Overall Instance Startup, see fm0 for more info -->
  <Name>fm1</Name> <!-- also for logging with _sm, _fe, _pm appended -->
  <Hfi>1</Hfi> <!-- local HFI to use for FM instance, 1=1st HFI -->
  <Port>2</Port> <!-- local HFI port to use for FM instance, 1=1st Port -->
  <PortGUID>0x0000000000000000</PortGUID> <!-- local port to use for FM -->
  <SubnetPrefix>0xfe80000000001001</SubnetPrefix> <!-- should be unique -->
  <!-- Overrides of the Common.Shared or Fm.Shared parameters if desired -->
  <!-- <LogFile>/var/log/fm1_log</LogFile> --> <!-- log for this instance -->
  <!-- <StartupRetries>5</StartupRetries> -->
  <!-- <StartupStableWait>10</StartupStableWait> -->
</Shared>

<Shared>
  <Start>0</Start> <!-- Overall Instance Startup, see fm0 for more info -->
  <Name>fm1</Name> <!-- also for logging with _sm, _fe, _pm appended -->
  <Hfi>1</Hfi> <!-- local HFI to use for FM instance, 1=1st HFI -->
  <Port>2</Port> <!-- local HFI port to use for FM instance, 1=1st Port -->
  <PortGUID>0x0000000000000000</PortGUID> <!-- local port to use for FM -->
  <SubnetPrefix>0xfe80000000001001</SubnetPrefix> <!-- should be unique -->
  <!-- Overrides of the Common.Shared or Fm.Shared parameters if desired -->
  <!-- <LogFile>/var/log/fm1_log</LogFile> --> <!-- log for this instance -->
  <!-- <StartupRetries>5</StartupRetries> -->
  <!-- <StartupStableWait>10</StartupStableWait> -->
</Shared>

  3. Edit the following settings:

    • Start = 1

      Initializes the SuperNIC.

    • Name = fmx

      where x is the next instance, less than or equal to the number of supported FM instances.

    • HFI = x+1

      For example, for fm2, HFI = 3.

    • Port = 1

    • SubnetPrefix = unique ID for target subnet

  4. Save the opafm.xml file.
