Operation Notes
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 a system startup from tape are recorded
and retained until the next system startup from tape. Newly assigned or
released global resource identification numbers (RINs) are permanently
recorded.
All communication lines must be closed before issuing a =SHUTDOWN command
or a manual halt of the system may be necessary. Note that data is lost
if a transmission is in progress when the halt is performed. If any
network service (NS) lines are left open when the =SHUTDOWN command is
issued, lines to the remote system remain open and any remote sessions
become 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 stop operation immediately upon receiving a =SHUTDOWN
command. A START RECOVERY retains spoolfiles which are printed when the
system is returned online.
You can use any of the 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.
Use
This command may be issued only at the physical console.
Example
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
=SHUTDOWN
10:49/#S40/25/LOGOFF
10:49/20/ALL JOBS LOGGED-OFF
To shut down the system in order to identify a DTC hang, use 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)
