Setting Up the System
Stopping the System
Warning: When using the shutdown procedure for your system, enter the correct command
before you stop the system. Failure to do so, may result in loss of data. Please refer to your
operating system documentation.
1. Exit any applications that are running. Consult the applications manuals for instructions.
2. Ensure that the media drives do not contain any media.
3. Exit the operating system using the appropriate shutdown command.
a. It is possible to execute the shutdown procedure from the system console (local or
remote line) with the CPU drawer key set to the Secure position. Remember, before
rebooting the system, to set the CPU drawer Key Mode Switch to the Normal or the
Service position.
b. When the shutdown program is executed, a warning message is sent to all
connected terminals. You can specify the time period between the sending of the
warning message and the system shutdown.
Here is an example:
shutdown –h +5r
represents a period of 5 minutes.
Warning: This period should allow all the users sufficient time to finish their sessions
and save their data. The amount of time can vary from a few seconds (allowing the
user to exit the vi editor, for example) to several minutes (allowing the user to properly
finish the update of a database). In the case of a user updating a database, if the
system is shutdown before the user has properly finished his update session, there
can be loss of important data.
4. Set the CPU drawer Key Mode Switch to the Power Off position.
Note: If nobody needs to use the system, set the Key Mode Switch to the Secure position
and remove the key, to prevent unauthorized reset of the system.
5. Switch off the external devices, if connected.
Note:
Do not power off any drawers included in high availability configurations.
Rebooting the System
A system reboot recopies the operating system from disk to memory and starts it without
turning the system completely off. Reboot is also known as a system reset. It reinitializes
the operating system by repeating the Initial Program Load (IPL) operation.
The reboot command synchronizes the hard disks and performs some other shutdown
activities without halting the system. Use the reboot command to reboot the operating
system when it is accessed by only one user. The shutdown command is used instead of
the reboot command when the system is running and multiple users are logged on.
Reboot to cause the system to recognize newly installed software, to reset peripheral
devices or to recover from a system crash.
To reboot the system you must have root user authority.
At the prompt, enter:
reboot
The system reboots.
