The SYSTEMS class contains information about the systems in the cluster.
  This class includes information such as the system ID, the node name,
  the type of system, the type of software, the software version, the
  number of virtual circuits, etc.

1  –  DG_SIZE

   Maximum number of bytes of application data in datagrams sent over
   the circuit.

2  –  HW_TYPE

   System hardware type (for example, VAXstation 3100 or HS70).
   (Enclose the system type between double quotation marks.)

3  –  HW_VERS

   Hardware configuration and revision levels of the remote system.

4  –  INCARNATION

   Unique 16-digit hexadecimal number established when the system is
   booted.

5  –  INCN_TIME

   Incarnation number expressed as a time (dd-mmm-yy hh:mm).

6  –  MSG_SIZE

   Maximum number of bytes of application data in messages sent over
   the circuit.

7  –  NODE

   Node name of the remote system. Normally, the cluster manager sets
   the node name using the system parameter SCSNODE. The node name
   should be the same as the DECnet node name. (Note that SCSNODE
   cannot be more than six characters.)

8  –  NUM_CIRCUITS

  Number of virtual circuits between the local system and remote systems.

9  –  SOFTWARE

   Name and version of the operating system currently running on the
   remote system.

10  –  SYS_ID

  Identification number of the remote system. Normally, the cluster
  manager sets this number using the system parameters SCSSYSTEMID and
  SCSSYSTEMIDH. This number should be the same as the DECnet node number.
