1.SYSMAN> SET ENVIRONMENT/CLUSTER
      %SYSMAN-I-ENV, Current command environment:
              Clusterwide on local cluster
              Username ALEXIS    will be used on nonlocal nodes

      This command defines the command environment as the local
      cluster. SYSMAN confirms the new environment.

    2.SYSMAN> SET ENVIRONMENT/NODE=NODE21/CLUSTER
      Remote Password:

      %SYSMAN-I-ENV, Current command environment:
              Clusterwide on remote node NODE21
              Username ALEXIS    will be used on nonlocal nodes

      This command establishes a management environment on the
      cluster where NODE21 is a member. SYSMAN prompts for a password
      because it is a nonlocal environment.

    3.SYSMAN> SET ENVIRONMENT/NODE=(NODE21,NODE22,NODE23)
      %SYSMAN-I-ENV, Current command environment:
              Individual nodes: NODE21,NODE22,NODE23
              Username ALEXIS   will be used on nonlocal nodes

      This command defines the management environment to be three
      individual nodes.

    4.$ CREATE/NAME_TABLE/PARENT=LNM$SYSTEM_DIRECTORY -
      _$ SYSMAN$NODE_TABLE
      $ DEFINE LAVCS SYS1,SYS2,SYS3,SYS4/TABLE=SYSMAN$NODE_TABLE
      $ RUN SYS$SYSTEM:SYSMAN
      SYSMAN> SET ENVIRONMENT/NODE=(LAVCS)
      %SYSMAN-I-ENV, Current command environment:
              Individual nodes: SYS1,SYS2,SYS3,SYS4
              Username ALEXIS   will be used on nonlocal nodes

      The commands in this example set up the logical name table
      SYSMAN$NODE_TABLE, define a logical name (LAVCS), and use the
      logical name to define the command environment.
