摘要： A partition manager includes a resource detection mechanism that uses a persistent resource database to determine which resources were seen previously, and to determine which resources are required for a logical partition to start. Once all required resources for a logical partition are detected, the logical partition is started. In this manner, a logical partition may be started as soon as all of its resources are available, without waiting on the resources of other logical partitions. In addition, a missing required resource will prevent a logical partition from starting, thus avoiding the crash of a logical partition due to missing resources.

摘要： A resource and partition manager of the preferred embodiments includes a lock mechanism that operates on a plurality of locks that control access to individual I/O slots. The resource and partition manager uses the lock mechanism to obtain a lock on an I/O slot when transferring control of the I/O slot to a logical partition that is powering on and when removing the I/O slot from a logical partition that is powering off. The resource and partition manager uses the lock mechanism to remove control of an I/O slot from, or return control to, an operating logical partition in order to facilitate hardware service operations on that I/O slot or on the physical enclosure in which it is contained.

摘要： A logically partitions computer system maintains a respective window for each of multiple cached state values which are subject to change. Where an individual change to a cached state value does not cause it to stray outside its window, then the change is made only to the cached state value, without triggering an updating operation. Where the change causes the cached state value to stray outside the window, an updating operation is triggered. Preferably, the system contains a global system clock, which is adjusted by an independent clock state delta value for each partition. A respective window is maintained for each clock delta. A global wake-up time for the system, determined as the earliest wake-up time of any partition, is re-computed when a change to a partition's clock causes its cached clock delta to stray outside the window.

摘要翻译： 逻辑分区计算机系统为可能发生变化的多个缓存状态值中的每一个维护相应的窗口。 如果个人更改为缓存状态值不会导致其超出其窗口，则仅对缓存状态值进行更改，而不会触发更新操作。 如果更改导致缓存状态值偏离窗口外，则会触发更新操作。 优选地，该系统包含全局系统时钟，该时钟由每个分区的独立时钟状态增量值调整。 为每个时钟增量维持相应的窗口。 当对分区的时钟进行更改时，系统的全局唤醒时间被确定为任何分区的最早唤醒时间，会导致其缓存的时钟增量偏离窗口外。

摘要： Methods, systems, and media for timed power-on in a logically partitioned environment are disclosed. Embodiments may disclose determining a time period based upon a time to launch a partition and a time of day associated with the next partition to launch. After determining the time period, a timer is set to boot the system based upon the time period. More specifically, embodiments allow the timed power-on (TPO) and time of day (TOD) of logical partitions to be modified by clients independently of other partitions by determining the system TPO based upon TPOs and TODs of logical partitions as well as the TOD of the system. Some embodiments include initiating a transaction like an interrupt in response to a change in a TPO or TOD of logical partition or the system. Several of such embodiments incorporate adjusting or re-calculating the system TPO in response to the transaction.

摘要： An apparatus, program product and method for managing a number of physical connections to a peripheral device. A multipath driver provides a logical connection interface to a client. This interface allows the client to efficiently access the peripheral device over one or more of the physical connections. In so doing, the logical connection interface associates connections with a primary connection, deletes inactive connections from memory, as well as updates and uses a list of active connections to seamlessly route data to the peripheral device.
