Reference informationUse the information in this section as needed to complete the storage enclosure installation andconfiguration tasks.Stopping a system or logical partitionLearn 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 theHardware Management Console (HMC) to stop the system can cause unpredictable results in the datafiles. Also, the next time you start the system, it might take longer if all applications are not ended beforestopping the system.To stop the system or logical partition, select the appropriate procedure.Stopping a system that is not managed by an HMCYou might need to stop the system to complete another task. If your system is not managed by theHardware Management Console (HMC), use these instructions to stop the system by using the powerbutton or the Advanced System Management Interface (ASMI).Before you stop the system, follow these steps:1. Ensure that all jobs are completed and end all applications.2. If a Virtual I/O Server (VIOS) logical partition is running, ensure that all clients are shut down or thatthe clients have access to their devices by using an alternative method.Stopping a system by using the control panelYou might need to stop the system to complete another task. If your system is not managed by theHardware Management Console (HMC), use these instructions to stop the system by using the powerbutton.The following procedure describes how to stop a system that is not managed by the HMC.1. Log in to the host partition as a user with the authority to run the shutdown or pwrdwnsys (PowerDown 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 thePWRDWNSYS command to power down the primary partition.The command stops the operating system. The system power turns off, the power-on light begins toslowly flash, and the system goes into a standby state.3. Record the IPL type and the IPL mode from the control panel display to help you return the systemto this state when the installation or replacement procedure is completed.4. Set the power switches of any devices that are connected to the system to off.Stopping a system by using the ASMIYou might need to stop the system to complete another task. If your system is not managed by theHardware Management Console (HMC), use these instructions to stop the system by using the AdvancedSystem Management Interface (ASMI).© Copyright IBM Corp. 2016, 2017 25
