Stopping a system

Learn how to stop a system as a part of a system upgrade or service action.

About this task

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 data files. Also, the next time you start the system, it might take longer if all applications are not ended before stopping the system.

Note: If the system is an IBM® Elastic Storage Server, work with the customer to stop the system.
