Enhancements Summary
Presently MPE/iX supports the =SHUTDOWN with console interrupt [CTRL] [A]. The =SHUTDOWN command performs an implicit =LOGOFF of all sessions, including the session logged at the system console. The CPU halts, and console interrupt [CTRL] [A] is ineffective. The objective of this enhancement is to provide the shutdown mechanism with a reboot option in the command level similar to HP-UX operating system. This enhancement provides a :SHUTDOWN command on the CI prompt, with a RESTART option which shuts down the system completely and reboots automatically.
Enhancement
:SHUTDOWN SYSTEM [;RESTART] Syntax :SHUTDOWN SYSTEM will shutdown the system completely. :SHUTDOWN SYSTEM;RESTART will shutdown the system completely and reboot the system automatically. Control will result to the ISL> prompt. This 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 the ALLOW command.
Parameters
- SYSTEM
- Specifies that the entire system should be shut down completely.
- RESTART
- Specifies that the system should be restarted after the shut down is complete.
Operation and Use of New Command
The MPE/iX operating system is shutdown in an orderly manner. :SHUTDOWN performs the same function as =SHUTDOWN, but may be entered from the CI in a job, session, or script. The :SHUTDOWN command supports the RESTART option.OP capability is required for this command. The :SHUTDOWN performs an implicit =LOGOFF of all sessions, including the session issuing the command. 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. 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
- Create a file called AUTOIN which contains the "START [NO]RECOVERY" command.
- Run FORMAT.MPEXL.SYS. This will create a file called AUTOOUT in the same group.
- Copy AUTOOUT,AUTOBOOT.MPEXL.SYS.
- Set the autoboot file with the SYSGEN utility.:SYSGEN
>sy
>aa file=autoboot.mpexl.sys;type=disc
>hold
>exit
>keep
>tape verbose - Perform a configuration UPDATE to your system with the CSLT tape created under SYSGEN.
- After UPDATE is complete, use the ISL AUTOBOOT command to
enable the autoboot feature. At the ISL prompt enter:
ISL> AUTOBOOT ON
ISL> START start_options
Note for AUTORESTART Product Users
There is no change in behavior for Autorestart product features due to the introduction of :SHUTDOWN CI command. However, when the :SHUTDOWN SYSTEM;RESTART command is issued and if the AUTOBOOT file has the DUMP command, the system will take a DUMP of the system and execute the rest of the commands in AUTOBOOT file. To disable taking full DUMP during normal shutdown and restart, you can use the Mini dump feature of the AUTORESTART product. It provides FULLDUMP, NULLDUMP and MINIDUMP options. Refer to the AUTORESTART User's Guide for details.Sample Output
