    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 logical partition (LPAR) computer system for managing partition configuration data is disclosed, which includes a nonvolatile memory, and a plurality of logical partitions, each running independently from the other logical partitions. The system also includes a console coupled to the computer system for accepting logical partition configuration data input by an operator. The configuration data entered by the operator specifies the processors, I/O, and memory allocated to each logical partition defined for the system. The system further includes a set of tables maintained in the nonvolatile memory for storing the logical partition configuration data, such that the logical partition configuration data is persistent across system power cycles.
