Stopping A System Or Logical Partition; Stopping A System That Is Not Managed By An Hmc Or An Sdmc - IBM 8202-E4B Manual

For instructions on working with the SDMC, see Managing and configuring the SDMC. For instructions
on starting a virtual server, see Managing virtual servers. For instructions on shutting down and
restarting virtual servers, see Shutting down and restarting virtual servers.
Progress indicators, also known as checkpoints, display on the control panel while the system is being
started. When the power-on light on the control panel stops flashing and remains on, the system power is
on.

Stopping a system or logical partition

Learn how to stop a system or logical partition as a part of a system upgrade or service action.
Attention: Using either the power-on button on the control panel or entering commands at the
Hardware Management Console (HMC) to stop the system can cause unpredictable results in the data
files. Also, the next time you start the system, it might take longer if all applications are not ended before
stopping the system.
To stop the system or logical partition, select the appropriate procedure.

Stopping a system that is not managed by an HMC or an SDMC

You might need to stop the system to perform another task. If your system is not managed by the
Hardware Management Console (HMC) or the IBM Systems Director Management Console (SDMC), use
these instructions to stop the system by using the power button or the Advanced System Management
Interface (ASMI).
Before you stop the system, follow these steps:
1. If an Integrated xSeries Adapter (IXA) is present on the system, shut it down using IBM i options.
2. Ensure that all jobs are completed and end all applications.
3. Ensure that the operating system is stopped.
Attention: Failure to do so can result in the loss of data.
4. If a Virtual I/O Server (VIOS) logical partition is running, ensure that all clients are shut down or that
the clients have access to their devices by using an alternate method.
The following procedure describes how to stop a system that is not managed by the HMC or the SDMC.
1. Log in to the system as a user with the authority to run the shutdown or pwrdwnsys (Power Down
System) command.
2. At the command line, enter one of the following commands:
v If your system is running the AIX operating system, type shutdown.
v If your system is running the Linux operating system, type shutdown -h now.
v 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.
3. At the Linux command line, type shutdown -h now.
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.
4. 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.
5. Set the power switches of any devices connected to the system to off.
