Power off system
Use the Power off system task to shut down the managed system. Powering off the managed system makes all partitions unavailable until the system is again powered on.
Before you power off the managed system, ensure that all logical partitions are shut down and
that their states have changed from Running to Not Activated. For
more information about shutting down a logical partition, see Shutdown partition
If you do not shut down all logical partitions on the managed system before you power off the managed system, the managed system shuts down each logical partition before the managed system itself powers off. This can cause a substantial delay in powering off the managed system, particularly if the logical partitions are not responsive. Further, the logical partitions might shut down abnormally, which might result in data loss and further delays when you activate the logical partitions once more.
- In the navigation area, click System resources, and then select Systems.
- Select the system that you want to power off, and then click . The Power off system window opens.
- Select one of the following options:
- Normal power off
- The Normal power off mode shuts down the system operations in a controlled manner. During the shutdown, programs that are running active jobs are allowed to perform cleanup (end-of-job processing).
- Fast power off
- The Fast power off mode shuts down the system by stopping all active jobs immediately. The programs running those jobs are not allowed to perform any cleanup. Use this option when you need to shut down the system because of an urgent or critical situation.
- Select Force power off to power off a managed system while a dump from the managed system is being offloaded to the HMC. It is recommended to wait until the dump offload operation is complete before powering off. If not, the dump might be corrupted or incomplete.
- Confirm the system name to be powered off, and click Power off.
