Abstract: A method, system, and apparatus for synchronizing device, node, and drawer addresses between two networks within a data processing system is provided. In one embodiment, a service processor assigns a plurality of SPCN addresses to each of a plurality of devices in the data processing system. System firmware then determines the RIO addresses corresponding to the plurality of devices. If one of the SPCN addresses is not the same as the RIO address for the corresponding device, node, or drawer, then the service processor reassigns a new SPCN address to the corresponding device, node, or drawer such that the new SPCN address is identical to the RIO address for a corresponding device, node, or drawer.

Abstract: A method, system, and product in a data processing system are disclosed for providing centralized management of a InfiniBand distributed system-area network that includes multiple end nodes. A manager application is established in one of the end nodes. An agent application is established in one or more end nodes. Each agent application is independent from the manager application. The manager application maintains a current list of active agent applications and uses the list to manage the agent applications in the end nodes.

Abstract: To emulate multi-threaded processing in an operating system supporting only single-threaded processes and single-level interrupts, the processor timer is started with a selected time-out period during execution of a master code thread. Processing of the master code thread proceeds until the timer interrupt, at which time the operating system timer interrupt service routine (ISR) transfers execution control to a slave code thread or slave code thread component. The slave code thread or component is executed in its entirety, at which time the timer is reset and execution control is returned to the master code thread, where processing resumes at the point during which the timer interrupt was asserted. To minimize disruption of the master code thread execution, a maximum latency should be enforced on the slave code thread, which may be accomplished by breaking the slave code thread into multiple components. The timer ISR maintains an index of the predetermined starting points within the slave code thread(s) with a pointer identifying the next slave code thread component to be selected when the timer interrupt is asserted. Processing thus alternates between the master code thread and the slave code thread or components, with different slave code thread components being selected in round-robin fashion. The duty cycle between the master code thread and the slave code thread or components may be varied by selection of the time-out period and the maximum latency allowed to slave code thread processing.

Abstract translation: 为了在仅支持单线程进程和单级中断的操作系统中模拟多线程处理，处理器定时器在执行主代码线程期间以选定的超时周期启动。 主代码线程的处理进行到定时器中断，此时操作系统定时器中断服务程序（ISR）将执行控制传送到从机代码线程或从机代码线程组件。 从机代码线程或组件全部执行，此时定时器复位，执行控制返回到主代码线程，其中处理在定时器中断被断言的时刻恢复。 为了最大限度地减少主代码线程执行的中断，应该在从属代码线程上执行最大延迟，这可以通过将从属代码线程分解成多个组件来实现。 定时器ISR在定时器中断被断言时用指示器识别待选择的下一个从机代码线程组件来保持从属代码线程内的预定起始点的索引。 因此，处理因此在主代码线程和从属代码线程或组件之间交替，其中以循环方式选择不同的从属代码线程组件。 主代码线程和从属代码线程或组件之间的占空比可以通过选择超时周期和允许从机代码线程处理的最大延迟来改变。

Abstract: At least one input/output (I/O) firmware partition is provided in a partitioned environment to facilitate access to I/O resources owned by the at least one I/O firmware partition. The I/O resources of an I/O firmware partition are shared by one or more other partitions of the environment, referred to as consumer partitions. The consumer partitions use the I/O firmware partition to access the I/O resources. Since the I/O firmware partitions are responsible for providing access to the I/O resources owned by those partitions, the consumer partitions are relieved of this task, reducing complexity and costs in the consumer partitions.

Abstract translation: 在分区环境中提供至少一个输入/输出（I / O）固件分区，以便于访问至少一个I / O固件分区拥有的I / O资源。 I / O固件分区的I / O资源由环境的一个或多个其他分区共享，称为消费者分区。 消费者分区使用I / O固件分区来访问I / O资源。 由于I / O固件分区负责提供对这些分区所拥有的I / O资源的访问，所以消费者分区可以免除此任务，从而降低了消费者分区中的复杂性和成本。

Abstract: A data processing system, method, and computer program product are disclosed for reporting a loss of a service application to a particular system administrator. The data processing system includes a logically partitioned computer system and a hardware management console. The hardware management console is a stand-alone system separate from the computer system. A service application is executable by the hardware management console for managing service of and placing service calls for the logically partitioned computer system. The logically partitioned computer system includes a service partition. A service processor included in the logically partitioned computer system monitors a presence of the service application, and reports the absence of the service application to the service partition. In response to an absence of the service application, the service partition reports the absence of the service application to a system administrator of the service partition.

Abstract: A hosting partition update mechanism allows updating the I/O capability of a logically-partitioned computer system in a way that minimally affects the performance and availability of I/O in the computer system. When an update is needed, a new hosting partition is created with the desired update(s). The I/O adapters in the current hosting partition are then migrated to the new hosting partition. The migration of an I/O adapter from the current hosting partition to the new hosting partition is relatively fast, thereby minimally impacting system performance and availability of I/O. Once all of the I/O adapters have been migrated to the new hosting partition, the current hosting partition may be kept as a backup, or may be eliminated. Providing a new or backup hosting partition allows updates to be performed in the new or backup hosting partition in a non-disruptive manner while the current hosting partition continues to service I/O requests.

Abstract: An I/O adapter sharing mechanism in a logically partitioned computer system allows sharing a network I/O adapter between logical partitions in an efficient manner. A first logical partition owns (or controls) the I/O adapter, and a second logical partition desires to use (or share) the I/O adapter. An I/O adapter device driver that includes a hardware interface is provided in the first logical partition. A virtual device driver is provided in the second logical partition that provides a set of functions that is at least partially defined by querying the I/O adapter device driver in the first logical partition. The I/O adapter sharing mechanism includes a transfer mechanism that allows data to be transferred directly from the virtual device driver in the second logical partition to the I/O adapter without passing through the I/O adapter device driver in the first logical partition.

Abstract: A system and method for monitoring a host computer using a service processor is provided. A shared nonvolatile random access memory (NVRAM) area is used to store progress information from the host computer system. The host computer system writes progress information corresponding to the initialization step being performed to the shared NVRAM and also updates a host pointer in the NVRAM. The service processor reads the shared NVRAM and compares its pointer with the host pointer to determine whether new host initialization activity has been reported. The service processor sets a timer so that if host activity is not reported during a set amount of time an error condition occurs causing the service processor to handle the host computer error. An optional service processor routine determines whether the host computer is stuck in an initialization loop whereupon the service processor once again handles the host computer error.

Abstract translation: 提供了一种使用服务处理器监视主机的系统和方法。 共享的非易失性随机存取存储器（NVRAM）区域用于存储来自主机系统的进度信息。 主计算机系统将与正在执行的初始化步骤相对应的进度信息写入共享NVRAM，并且更新NVRAM中的主机指针。 服务处理器读取共享NVRAM并将其指针与主机指针进行比较，以确定是否已经报告了新的主机初始化活动。 服务处理器设置定时​​器，使得如果在设定的时间内没有报告主机活动，则出现错误状况导致服务处理器处理主机错误。 可选的服务处理器例程确定主计算机是否卡在初始化循环中，服务处理器再次处理主计算机错误。
