Shutdown partition

You can shutdown a partition and the associated partition profile by using the Hardware Management Console (HMC).

For IBM® i logical partitions, use this page only if you cannot shut down the IBM i logical partition from the command line of the operating system. Using this page to shut down an IBM i logical partition results in an abnormal IPL.

If you choose to shut down VIOS partitions that are acting as the Paging Service Partition (PSP) for a number of client partitions, a warning message is displayed, indicating that you must shut down the client partitions before you shut down the VIOS partition.

Complete the following steps to shutdown partitions:

  1. In the navigation area, click System resources > Partitions.

    Alternatively, you can click System resources > Systems. Click a system from the list. Click Partitions. The Partitions page is displayed.

  2. Select a single partition or multiple partitions that you want to shutdown.
  3. Click Operations > Shutdown Partition. The Shutdown Partition page is displayed.
  4. Select one of the following options:
    Delayed The HMC shuts down the logical partition using the delayed power-off sequence. This allows the logical partition time to end jobs and write data to disks. If the logical partition is unable to shut down within the predetermined amount of time, the shutdown operation ends abnormally and the next restart may be longer than normal.
    Immediate

    The HMC shuts down the logical partition immediately. The HMC ends all active jobs immediately. The programs running in those jobs are not allowed to perform any job cleanup. This option might cause undesirable results if the data is partially updated. Use this option only after a controlled shutdown is unsuccessfully attempted.
    Operating System
    The HMC shuts down the logical partition normally by issuing the shutdown command to AIX® or Linux® logical partitions, and PWRDWNSYS OPTION(*CNTRLD) command to IBM i logical partitions.
    Note: This option is available in AIX or Linux systems, only if the RMC state is active. For IBM i systems, this option is available only if the partition is in a running state.
    Operating System Immediate
    The HMC shuts down the logical partition immediately by issuing the shutdown -F command to AIX or Linux logical partitions, and PWRDWNSYS OPTION(*IMMED) command to IBM i logical partitions.
    Note: This option is available in AIX or Linux systems, only if the RMC state is active. For IBM i systems, this option is available only if the partition is in a running state.
    Note:
    • For all partitions except the IBM i partition, the Resource Monitoring and Control (RMC) state must be active to select the Operating System or the Operating System Immediate options.
    • It is recommended to use either the Operating System or the Operating System Immediate option to shut down an IBM i logical partition. The IBM i logical partition must have the code level IBM i 7.2 TR 1 or IBM i 7.1 TR 9, or later. If these options are not available, it is recommended you issue the PWRDWNSYS OPTION(*CNTRLD) or PWRDWNSYS OPTION(*IMMED) command in the command-line interface of the operating system. Using the Delayed or Immediate options to shut down an IBM i logical partition results in an abnormal Initial program load (IPL).
  5. Confirm the partitions that you want to shutdown, and click Shutdown.
    Note:

    • You can view the progress of the shutdown operation with the progress bar and through the task notifications.

    • If the partition shutdown operation is not successful, an error message is displayed.
