Stopping a system by using the HMC

You can use the Hardware Management Console (HMC) to stop the system or logical partition.

About this task

By default, the managed system is set to power off automatically when you shut down the last running logical partition on the managed system. If you set the managed system properties on the HMC such that the managed system does not power off automatically, you must use this procedure to power off your managed system.
Attention: Ensure that you shut down the running logical partitions on the managed system before you power off the managed system. Powering off the managed system without shutting down the logical partitions first causes the logical partitions to shut down abnormally and can cause data loss. If you use a Virtual I/O Server (VIOS) logical partition, ensure that all clients are shut down or that the clients have access to their devices by using an alternative method.
To power off a managed system, you must be a member of one of the following roles:
  • Super administrator
  • Service representative
  • Operator
  • Product engineer
    Note: If you are a product engineer, verify that the customer has shut down all active partitions and has powered off the managed system. Continue with the procedure only after the status of the server changes to Power Off.
