Configuring and cabling CNA ports (80xx, FAS2600 series, FAS2552, and FAS2554 systems only)

If you are adding a controller module to an 80xx, FAS2600 series, FAS2552, or FAS2554 system, you must check the configuration of the CNA ports on the new controller module and, if necessary, change the default port configuration to match the CNA port configuration of the existing controller module.

Before you begin

You must have the SFP+ modules for the CNA ports. If the ports are set to a 10 GbE personality, you can use twinax cables.

Steps

  1. Boot to Maintenance mode on the new node, if it is not in Maintenance mode, by entering halt to go to the LOADER prompt.
    If you are running ONTAP 8.2.1 or later, enter boot_ontap maint at the LOADER prompt and enter y to continue when prompted.
  2. On the existing controller module console, check how the ports are currently configured: system node hardware unified-connect show
    Example

    The system displays output similar to the following example:

    node_name::> system node hardware unified-connect show
                   Current Current   Pending  Pending   
    Node  Adapter  Mode    Type      Mode     Type      Status
    ----  -------  ------- --------- -------  -------   ------
    f-a    0e      fc      initiator -        -         online
    f-a    0f      fc      initiator -        -         online
    f-a    0g      cna     target    -        -         online
    ...
    
  3. On the console of the new node, display the port settings: ucadmin show
    Example

    The system displays output similar to the following example:

    *> ucadmin show
                   Current Current   Pending  Pending   
    Node  Adapter  Mode    Type      Mode     Type      Status
    ----  -------  ------- --------- -------  -------   ------
    f-a    0e      fc      initiator -        -         online
    f-a    0f      fc      initiator -        -         online
    f-a    0g      cna     target    -        -         online
    ...
  4. If the current SFP+ module does not match the desired use, replace it with the correct SFP+ module.
  5. If the current configuration does not match the existing node's configuration, change the configuration as required:
    If the desired use is for... Then enter the following command...
    FC initiator ucadmin modify -t initiator adapter_name
    FC target ucadmin modify -t target adapter_name
    Ethernet ucadmin modify -m cna adapter_name
    Note: If you changed the port configuration, it will take effect when the new node is booted. To confirm the configuration change, you must verify the settings after the boot.
  6. Cable the port.
