SHUTDOWN — New CI Command
95
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.
Presently =SHUTDOWN can be issued only at the physical console. The :SHUTDOWN command can be issued
from a session, job, program, or in BREAK. Pressing
[Break] has no effect on this command. It can be issued
only from the console unless it is distributed to users with OP capability via the ALLOW command.
Example
To shut down the MPE/iX operating system enter:
:SHUTDOWN SYSTEM
This will shutdown the system completely.
To shut down the MPE/iX operating system and initiate a subsequent reboot operation enter:
:SHUTDOWN SYSTEM ;RESTART
This will shutdown the system completely and reboot the system automatically. Operator control will resume
at the ISL> prompt.
Using AUTOBOOT Feature with :SHUTDOWN;RESTART Option
Autobooting allows you to boot the system from the primary boot path without the need to make any
keyboard entries. This existing feature can be combined with :SHUTDOWN SYSTEM;RESTART command
to restart the system without the interaction in ISL> prompt. More information on setting-up and using
AUTOBOOT feature is available in System Startup, Configuration, and Shutdown Reference Manual.
The RESTART command interacts with the AUTOBOOT feature of MPE/iX in order to minimize operator
intervention. When the AUTOBOOT feature is not enabled on the system the control is returned to the ISL>
prompt. When the AUTOBOOT feature is enabled as described in this section, the system is restarted
automatically.
As part of setting-up AUTOBOOT feature an autoboot file needs to be created. To facilitate the easy creation
of the file, an utility FORMAT.MPEXL.SYS is made available as part of this enhancement. FORMAT utility
enables user to create a specially formatted file that contains the special sequence of startup commands. The
system automatically executes these commands in sequence during system startup if this feature is activated.
Steps to Build and Setup an AUTOBOOT file
1. Create a file called AUTOIN which contains the “START [NO]RECOVERY” command.
2. Run FORMAT.MPEXL.SYS. This will create a file called AUTOOUT in the same group.
3. Copy AUTOOUT,AUTOBOOT.MPEXL.SYS.
4. Set the autoboot file with the SYSGEN utility.:SYSGEN
