=SHUTDOWN


     Initiates a shutdown of MPE/iX.

SYNTAX


     =SHUTDOWN [system  ]
               [terminal]
               [dtc     ]
               [tape    ]
               [disk    ]
               [network ]
               [other   ]


PARAMETERS


     None.


OPERATION


     The =SHUTDOWN command performs an implicit =LOGOFF of all
     sessions, including the session logged at the system
     console.  All system processes are stopped in an orderly
     fashion.  This includes the completion of all pending system
     activity and any processing necessary to ensure that the
     integrity of all system tables and directories is
     maintained.  Once these procedures are complete, SHUT is
     displayed on the console, the CPU halts, and console
     interrupt ([CTRL][A]) is ineffective.

     Device configuration changes that were made after the
     preceding load (UP, DOWN, ACCEPT, REFUSE and spooling
     commands) are not retained.  Configuration changes made
     during coldload are permanently recorded and retained until
     the next tape coldload.  Newly assigned or released global
     Resource Identification Numbers (RINs) are permanently
     recorded.

     All communication lines must be closed before issuing a
     =SHUTDOWN command.  Otherwise, a manual halt of the system
     may be necessary.  Note that data will be lost if a
     transmission is in progress when the halt is performed.
     Also, if NS lines were left open before issuing the
     =SHUTDOWN, lines to the remote system remain open and
     any remote sessions will be effectively "hung".  In this
     case, the remote system's operator may need to issue
     ABORTIO commands for the hung sessions and then abort the
     sessions themselves.

     Spooled devices will stop operation immediately upon
     receiving a =SHUTDOWN command.  A START RECOVER will keep spool
     files so that they may be printed when the system is
     returned online.

     The following options are available for the =SHUTDOWN command:

        o system
        o dtc
        o terminal
        o tape
        o disc
        o other

     You can use these options to indicate the reason that you are
     shutting down the system.  These options were developed to
     identify any possible type of system hang that might occur.
     For example, if you shutdown to clear a DTC hang, you can use
     the =SHUTDOWN dtc option.

     This command may be issued only at the physical console.


EXAMPLE(S)


     To shut the system down, first issue a warning to all users
     to allow them time to log off, and then execute =SHUTDOWN as
     shown below

     WARN @;SYSTEM WILL SHUTDOWN IN FIVE MINUTES. PLS LOG OFF.

     [CTRL][A]         ** Press [A] and [CTRL] simultaneously. **
     =SHUTDOWN
     1049/#S40/25/LOGOFF
     1049/20/ALL JOBS LOGGED-OFF

     the dtc option.  The console responds by listing shutdown
     messages similar to these:


     CTRL A
     =SHUTDOWN dtc

     Shutdown of operating system begins. (Shut 1)
     Shutdown of user processes begins. (Shut 2)
     Shutdown of jobs & sessions begins. (Shut 3)
     Spoolers notified of a shutdown. (Shut 16)
     Shutdown of system processes begins. (Shut 4)
     Shutdown of system managers begins. (Shut 5)
     Shutdown of operating system complete. (Shut 6)
