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)
