Stopping a system by using the HMC
You can use the Hardware Management Console (HMC) to stop the system or logical partition.
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 so that
the managed system does not power off automatically, you must use this procedure to power off your
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:
v Super administrator
v Service representative
v 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.
