Performing an immediate power off

You can power off your system faster by using the immediate power off function. Typically, this option is used when an emergency power off is needed. The operating system is not notified before the system is powered off.

Attention: To avoid experiencing data loss and a longer IPL the next time the system or logical partitions are booted, shut down the operating system prior to performing an immediate power off.

To perform this operation, you must have one of the following authority levels:

Administrator
Authorized service provider

To perform an immediate power off, do the following steps:

On the ASMI Welcome pane, specify your user ID and password, and click Log In.
In the navigation area, expand Power/Restart Control and select Immediate Power Off.
Click Continue to perform the operation.
