       /NODE=(node1,node2,...)

    Specifies that SYSMAN execute subsequent commands on the given
    DECnet nodes. If accompanied by the /CLUSTER qualifier, the
    environment becomes the cluster where the given DECnet node is
    a member. A node name can be a system name, cluster alias, or
    logical name. However, before you can use logical names to define
    the command environment, you must set up the logical name table
    SYSMAN$NODE_TABLE. For more information about defining the SYSMAN
    logical name table, refer to the OpenVMS System Manager's Manual.
