摘要： A method, apparatus, and computer instructions for halting input/output error propagation in the logically partitioned data processing system. All components associated with the bridge are identified to form a set of failed components in response to detecting an error state in a bridge within a set of bridges in the logical partitioned data processing system. An identification of the failed components is stored in which the identification is used by each partition during a boot process.

摘要： A method of virtually removing field replaceable units (FRUs) from a computer system during concurrent maintenance operations. Firmware within a flexible service processor (FSP) assigns unique resource identification (RID) numbers to each FRU in the computer system. The firmware collects vital product data (VPD) for each FRU and generates a duplicate test shared library, which is stored in a memory directory corresponding to the FSP. When the firmware receives input from a graphical user interface (GUI) that includes at least a first FRU selected for virtual removal from the computer system, the firmware adds the RID number of the selected FRU to the memory directory and recollects VPD. The FSP subsequently ignores any FRUs corresponding to RID numbers stored in the memory directory during operation of the computer system.

摘要： A interrupt is generated for all processors in a multiprocessor system when a critical datapath experiences an error. Serialization code in the interrupt handling routine for that interrupt suspends all processors except one and places the suspended processors in a waiting queue while the one processor handles the error. After the error has been handled, the remaining processors are allow to execute the interrupt handler, which simply exits detecting no error.

摘要： A method, computer program product, and data processing system for handling errors or other events in a logical partition (LPAR) data processing system is disclosed. When an operating system is initialized in a logical partition, it registers its capabilities for handling particular errors or other events with management software. When an error or other event affecting that logical partition occurs, the management software checks to see if the particular error or event is one that the operating system is capable of handling. If so, the operating system is notified. Otherwise, the management software directs the operating system to take other appropriate action, such as termination of the operating system and/or partition.

摘要： 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.

摘要： An apparatus, program product and method propagate errors detected in an IO fabric element from an IO fabric that is used to couple a plurality of endpoint IO resources to processing elements in a computer. In particular, such errors are propagated to the endpoint IO resources affected by the IO fabric element in connection with recovering from the errors in the IO fabric element. By doing so, a device driver or other program code used to access each affected IO resources may be permitted to asynchronously recover from the propagated error in its associated IO resource, and often without requiring the recovery from the error in the IO fabric element to wait for recovery to be completed for each of the affected IO resources. In addition, an IO fabric may be dynamically configured to support both recoverable and non-recoverable endpoint IO resources. In particular, IO fabric elements within an IO fabric may be dynamically configured to enable machine check signaling in such IO fabric elements in response to detection that an endpoint IO resource is non-recoverable in nature. The IO fabric elements that are dynamically configured as such are disposed within a hardware path that is defined between the non-recoverable resource and a processor that accesses the non-recoverable resource.

摘要： A method, system, and computer program product for enforcing logical partitioning of a shared device to which multiple partitions within a data processing system have access is provided. In one embodiment, a firmware portion of the data processing system receives a request from a requesting device, such as a processor assigned to one of a plurality of partitions within the data processing system, to access (i.e., read from or write to) a portion of the shared device, such as an NVRAM. The request includes a virtual address corresponding to the portion of the shared device for which access is desired. If the virtual address is within a range of addresses for which the requesting device is authorized to access, the firmware provides access to the requested portion of the shared device to the requesting device. If the virtual address is not within a range of addresses for which the requesting device is authorized to access, the firmware denies the request.
