Shutting down IBM i logical partitions by using the HMC

You can shut down IBM® i logical partitions by using the Hardware Management Console (HMC).

Before you begin

Before you shut down the IBM i logical partition, complete the following tasks:
  1. If an integrated server is active on the system, shut down the integrated server using IBM i options.
  2. Ensure that all jobs are completed and all applications are ended.
  3. Ensure that your partition profiles are updated with any dynamic partitioning resource changes that you want to keep when you restart the logical partition.

About this task

The correct way to shut down an IBM i logical partition from the HMC is to open an HMC 5250 emulator session and run the Power® Down System (PWRDWNSYS) command.

To shut down an IBM i logical partition from the HMC, follow these steps:

Procedure

  1. In the navigation pane, click the Resources icon The icon represents the Resources function of the HMC.
  2. Click All Partitions. Alternatively, click All Systems. In the work pane, click the server name that has the logical partition. Click View System Partitions. The All Partitions page is displayed.
  3. Select the logical partition and click Actions > Console > Open Dedicated 5250 Console.
  4. From the IBM i command line in the emulator session, type PWRDWNSYS OPTION (*CNTRLD) DELAY (600) and press Enter.
    The system will only shut down the IBM i logical partition you selected. The PWRDWNSYS command does not affect other IBM i logical partitions on your system. If you enter the PWRDWNSYS command with the RESTART(*YES) option, the operating system restarts, and the resource specifications of the logical partition remain the same. If you do not use the RESTART(*YES) option, then the logical partition shuts down completely, and other logical partitions will be able to take and use the resources that were used by the logical partition. Also, when you reactivate the logical partition using a partition profile, the partition profile overlays the resource specifications of the logical partition with the resource specifications in the partition profile. Any resource changes that you made to the logical partition using dynamic partitioning are lost when you reactivate the logical partition using a partition profile. If the logical partition is set to start automatically when the managed system starts, you can preserve the resource specifications on that logical partition by restarting the entire managed system using the Partition autostart power-on mode. When the logical partitions start automatically, the logical partitions have the resource specifications that the logical partitions had when you shut down the managed system.
  5. If the PWRDWNSYS command does not work, you can use either a delayed shutdown or an immediate shutdown to shut down the IBM i logical partition.
    Attention: Using these methods can cause an abnormal shutdown and can result in loss of data.
