Verify Connectivity

  1. Identify the prerequisite and subsequent installation tasks that you must perform in conjunction with this task.

    See Installation Task Overview.

  2. If you are at the switch, check the Link LEDs of the SFP+ and RJ-45 connectors.

    See LED Status for a description of Link LED states.

  3. Access the Oracle ILOM CLI.

    See Log In to the SP (SER MGT) or Log In to the SP (Network Management).

  4. Verify Ethernet connectivity.
    1. Start the EMS console.
      -> start /System/Networking/Switches/Switch_0/fs_cli
      Are you sure you want to start /System/Networking/Switches/Switch_0/fs_cli
      (y/n)? y

      SEFOS#

      In the output, Port is the port as seen on the rear panel. Ports Gi0/25 and Gi0/26 are internal to the switch architecture. Ports Ex0/1 and Ex0/2 are the two SFP+ uplink ports. The Status is the state of the port. The Duplex, Speed, and Negotiation are the parameters of the link. The Capability indicates if auto-crossover capability is on.

    4. If the status of a known-connected port is anything other than connected, investigate why.

      Refer to the EMS module documentation.

    5. Exit the EMS console.
      SEFOS# exit
      Connection closed by foreign host

  5. Verify IB and gateway connectivity.
    1. Start the host console.
      -> start /HOST/console
      Are you sure you want to start /HOST/console (y/n)? y
       
      Serial console started.  To stop, type ESC (
    2. Press Enter.

      where:

      • user is the current username.

      • hostname is the host name of the SCP.

    3. Switch to user admin with password admin.
      [user@hostname ~]# su admin

      If this is the first time Oracle Fabric OS is accessed, the Oracle Fabric OS configuration wizard might start. If this happens, see Run the Oracle Fabric OS Configuration Wizard.

    4. Display the state of the gateway ports.
      [OFOS] show ioports
      name     type                   state                descr     v-resources

      8 records displayed
      [OFOS] 

      In the output, the name is the port number as seen on the rear panel. The state is of the local port/peer port. The descr is the node descriptor of the peer port. The v-resources are the number of VLANs and VNICs supported on that port.

    5. Display the state of the IB ports.
      [OFOS] show infiniband-port
      name             state               mode_state             guid

      30 records displayed
      [OFOS] 

      In the output, the name is the port number as seen on the rear panel. The state is of the local port/peer port. The mode_state is the condition of the link. The guid is the GUID of the peer port.

    6. If in the output of these commands a port is identified as being in a down state, or if a link mode_state is other than switching, investigate why.

      Refer to the Oracle Fabric OS documentation for assistance.

    7. Exit the host console.

      Type exit and press the Enter key, then press the Esc key and type (.

      [OFOS] exit
      [root@nsn156-168 ~]#
      Serial console stopped.
      ->
  6. Administer the switch from Oracle Fabric Manager or Oracle Fabric OS.
