You might need to stop the system to complete another task. If your system is not managed
by the Hardware Management Console (HMC), use these instructions to stop the system by using the power
button.
The following procedure describes how to stop a system that is not managed by the HMC.
- Log in to the host partition as a user with the authority to run the
shutdown or pwrdwnsys (Power Down System) command.
- At the command line, enter one of the following commands:
- If your system is running the AIX® operating system,
type shutdown.
- If your system is running the Linux operating system,
type shutdown -h now.
- If your system is running the IBM® i operating system,
type PWRDWNSYS. If your system is partitioned, use the PWRDWNSYS
command to power down each of the secondary partitions. Then, use the PWRDWNSYS
command to power down the primary partition.
The command stops the operating system. The system power turns off, the power-on light begins to
slowly flash, and the system goes into a standby state.
- Record the IPL type and the IPL mode from the control panel display to help you return the
system to this state when the installation or replacement procedure is completed.
- Set the power switches of any devices that are connected to the system to off.
