5.2.4 How to Remove an Adapter From a NAFO Group

Remove backup adapters from an existing NAFO group to enable the adapter to be removed from the system, to be replaced, or to be reconnected to a different subnet and used as backup for another NAFO group.


Caution - Caution -

Removing the last backup adapter from a NAFO group results in no protection against faults detected on the active adapter, reducing public network availability for the cluster node.


  1. If you want to remove the active adapter, first switch to another adapter in the group.

    See "5.2.5 How to Switch a NAFO Group's Active Adapter".

  2. As superuser, remove the adapter from the NAFO group.


     # pnmset -c nafo-group -o remove adapter
    
    -c nafo-group

    Specifies the NAFO group from which to remove the adapter.

    -o remove adapter

    Removes the adapter from the NAFO group.

  3. Verify the status of the NAFO group.

    The deleted adapter should not appear in the listing for the NAFO group.


    # pnmstat -l
