Abstract: PROBLEM TO BE SOLVED: To provide an improved method, a device and a computer instruction for reporting an error log in an LPAR (logical partitioning) data processing system.
SOLUTION: This invention provides the method, the device and the computer instruction for managing the error log. A request is received from a partition within a plurality of partitions in the LPAR data processing system to access error information. Whether the error information is present in a buffer or not is determined. In response to that the error information is not present in the buffer, the error information is searched from a nonvolatile memory. The obtained error information searched from the nonvolatile memory is stored in the buffer. The error information is stored in the buffer only for a prescribed period of time. After the period of time, the error information is deleted or removed from the buffer. The outdated error information is not returned to the plurality of partitions.

Abstract: PROBLEM TO BE SOLVED: To provide a method and a device for managing an object set for plural terminals, and a computer-performed command. SOLUTION: An object set is stored in a memory such as a nonvolatile random access memory in a data processing system. The object set is used for structuring logical partitions in the data processing system. Access to the object set is provided to the plural terminals through a service processor.

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.
