Initiates a shutdown of MPE/iX.
=SHUTDOWN [system ]
[terminal]
[dtc ]
[tape ]
[disk ]
[network ]
[other ]
None.
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.
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)
