摘要： 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.

摘要： A method, system, and product are described for creating and managing affinity between memory and processors in logical partitions in a data processing system. The data processing system includes multiple processors. A memory affinity data structure is established. The memory affinity data structure identifies ones of the processors that have a close affinity with each one of multiple regions of the system memory. A memory affinity parameter is established and is utilized to determine whether memory affinity is required for each one of the logical partitions. In response to a determination that memory affinity is required for one of the logical partitions, the memory affinity data structure is utilized by a partition manager for the logical partition to allocate an optimal amount of memory that has a close affinity to ones of the processors that are assigned to the logical 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： A method, apparatus, and computer instructions for recovering terminated partitions in a logical partitioned data processing system. A termination of a partition in a set of partitions associated with a host bridge in the logical partitioned data processing system is detected. The state of other partitions within the set of partitions is checked in response to detecting the termination. A recovery process is initiated if all partitions in the set of partitions have terminated. Input/output slots associated with the host bridge are reset to a normal state if the recovery process is successful. The set of partitions is rebooted after resetting the input/output slots associated with the host bridge without rebooting the logical partitioned data processing system.

摘要： A system for managing input/output drawers within a data processing system. A unique identifier is assigned to each of a plurality of drawers, and is used by the operating system to identify the drawers in the system regardless of how these drawers are interconnected. Another unique PCI-bridge identifier is assigned to each of a plurality of PCI Host bridges (PHBs) from all drawers, and is used by the operating system to perform input/output processes to devices associated with the plurality of PHBs such that the ODM object for each of the PHBs remains the same regardless of how the drawer is interconnected in the system. When a new drawer is added to the system, a new unique identifier is assigned to the new drawer ensuring that the unique identifiers previously assigned to the other drawers are not used to identify the new drawer.

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.

摘要： A method for managing deadlock in a data processing system during an IPL process includes monitoring the usage of locks in the Hardware Object Model (HOM) of the data processing system. The process further includes detecting a deadlock condition in response to an indication of the IPL process in the data processing system entering a hung state when at least one lock is in use. The process further includes handling the deadlock condition by performing one or more of the following: recording error information for the deadlock condition, and terminating the IPL process.
