Abstract: A method, apparatus, and computer implemented instructions for controlling power in a data processing system having a plurality of logical partitions. Responsive to receiving a request to turn off the power for a logical partition within the plurality of logical partitions in the data processing system, a determination is made as to whether an additional partition within the plurality of logical partitions is present in the data processing system. The power is turned off in the data processing system in response to a determination an additional partition within the plurality of logical partitions is absent in the data processing system. The logical partition is shut down in response to a determination that an additional partition within the plurality of logical partitions is present in the data processing system. The mechanism of the present invention also provides for rebooting logical partitions. A request is received to reboot a logical partition within the plurality of logical partitions. A reset signal is activated only for each processor assigned to the logical partition.

Abstract: A method, apparatus, and computer instructions for managing a set of processors. In response to a request to deallocate a processor assigned to a partition within the logical partitioned data processing system, the process or in the set of processors, is stopped. In response to stopping the processor, the processor is placed in an isolated state in which the processor is isolated from the partition. The processor is then placed in a pool of resources for later reassignment.
