摘要： A method, system, and apparatus for reestablishing communications between a host and a service processor after the service processor has ceased to function correctly is provided. In one embodiment, the host exchanges heartbeat signals with the service processor. The heartbeat signals indicate that the service processor is active and functioning. In response to a failure to receive a heartbeat signal or in response to some other indication that the service processor is not performing correctly, the host causes a hard reset of the service processor. In addition, the service processor can detect a failure within itself and initiate a hard reset to itself. After the hard reset, the service processor returns to a monitoring mode without performing initial tests of the data processing system. Furthermore, the data processing system remains active and is not shut down during the hard reset of the service processor.

摘要： A method, a system and a computer program product for selecting a primary controller for a server system based on the services offered by each controller. A primary controller designator (PCD) utility determines the relative importance of a controller based upon the services provided by the controller and the weighted importance assigned to these services. The PCD utility classifies the services provided by a system-controller according to the following: (1) the number of OS partitions a system-controller is able to communicate with; and (2) the number of hardware devices that a controller has access to. The importance of the services is determined by the host OS partition information and the degree of importance of a partition that utilizes/requires the particular service(s). The PCD utility designates a controller as a “Primary” if the designated “Primary” is capable of providing services that are required for the most important OS partitions, according to the classification of controller services.

摘要： A method, apparatus and computer program product are provided for implementing atomic data tracing in a processor system including an auxiliary processor unit (APU) coupled to a central processor unit (CPU). The auxiliary processor unit (APU) processes a trace instruction. When a trace instruction is identified by the APU, the APU signals the CPU with a pipeline stall signal for stalling the CPU and checks for an enabled trace engine as specified by the trace instruction. When the trace engine for the trace instruction is enabled, then the trace data is written into a trace buffer. The APU signals the CPU with an op done signal for allowing the CPU to continue with instruction processing.

摘要： The aspects of the present invention provide a computer implemented method, an apparatus, and a computer usable program code for identifying a service processor with current setting information. First stored information for a service processor is retrieved from a first memory in the first service processor. Second stored information for the service processor is retrieved from a second memory in a data processing system to which the service processor is connected. The first stored information is compared with the second stored information to form a comparison as to whether the service processor was previously connected to the data processing system and to determine whether the service processor was a last service processor to fully communicate with system firmware in the data processing system. The service processor has current setting information if the service processor was previously connected to the data processing system and was the last service processor to fully communicate with the system firmware.

摘要： A method, system, and computer usable program product for managing multi-node multi-version systems are provided in the illustrative embodiments. A process associates a version identifier with a first version of data available at a first node in the multi-node multi-version system. The version identifier corresponds to the first version of the data. The data includes an update. The process sends the data and the associated version identifier to a second node without learning a second version of data available at the second node. In one embodiment, the first version of data may be a subset of the second version of data. In another embodiment the second version of data may be a subset of the first version of data. The process repeats the sending for each update at the first node.

摘要： In response to the start of an initialization sequence at a service processor, if power to a main processor was interrupted at a most-recent time that an operating system executed on the main processor, power to the main processor is turned on, the operating system is started executing on the main processor, data from the non-volatile memory of the service processor is provided to the operating system, and the service processor is reset, which restarts the initialization sequence. If the power to the main processor was not interrupted at the most-recent time that the operating system executed on the main processor, and if the operating system is currently executing on the main processor, a monitoring function is started in the service processor, which monitors for errors at a computer system.
