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 managed system.
Attention: If possible,
shut down the running logical partitions on the managed system before
powering 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 using an alternate method.

- Super administrator
- Service representative
- Operator
- Product engineer
Use the following steps to stop the system by using the
