The Alias module provides the means to define an alternate network
    address which is shared by multiple nodes in the same VMScluster.
    This makes it possible to treat a VMScluster, or several nodes
    within a VMScluster, as though it were a single node in the network.

    The first node in the VMScluster to create an Alias Port for
    a particular alias address causes that alias to be created.
    Subsequent nodes which create an Alias Port for the same alias
    establish connections (Ports) to that alias. The alias becomes
    active when the first node enables its Alias Port for that alias.
    The port-name refers to the port managed by this command.

                                   NOTE

       When a node enables an Alias Port, that node registers
       itself with other members of the alias.

1  –  Subentities

    The subentity of the Alias module is:

    Node___Alias___Port

    The ALIAS entity is the top-level entity in the hierarchy
    belonging to the Alias module. The entity is the root from which
    Alias Port subentity may be defined.

    The ALIAS PORT entity provides the means to define an alternate
    network address for this node, which is shared by other nodes
    in the same VMScluster. When the alias port entity is enabled,
    this node becomes an active member of the VMScluster alias it
    specifies.
