摘要： A communication-path management system includes a path-detection component for identifying all communications paths between a host computer, through a controller, to a data storage device. Once identified, the communication paths are incorporated into a logical-path mask. The path-detection component recognizes each path as either preferred or non-preferred based on latency, bandwidth, availability, or other user-defined criteria and divides the logical-path mask into a preferred path subset and a non-preferred path subset. If a valid path exists in the preferred path subset, all communications from the host computer to the data storage device transit paths belonging to this subset. Otherwise, active control is given to the non-preferred path subset. A channel subsystem manages actual communication based on resource allocation and contention using the currently active subset.
摘要翻译：通信路径管理系统包括用于识别通过控制器的主机与数据存储设备之间的所有通信路径的路径检测组件。一旦识别，通信路径被合并到逻辑路径掩码中。路径检测组件基于延迟，带宽，可用性或其他用户定义的标准将每个路径识别为优选的或不优选的，并将逻辑路径掩码划分成优选的路径子集和非优选的路径子集。如果优选路径子集中存在有效的路径，则从主计算机到数据存储设备的所有通信都将传输属于此子集的路径。否则，给予非优选路径子集的主动控制。信道子系统使用当前活动的子集来管理基于资源分配和争用的实际通信。

摘要： Provided are a method, system, and program for reassigning storage volumes from a failed processing system to a surviving processing system. A first processing system detects a failure of a second processing system. The first processing system determines device groups of storage devices managed by the failed second processing system and determines for each determined device group, hosts that connect to storage devices in the device group. The first processing system sends, for each device group, a unit check to each determined host indicating failure of each device group through one storage device in the device group to which the determined host connects. The determined hosts execute instructions to terminate any I/O operations in progress on the storage devices in the device group in response to the unit check indicating failure of one storage device in the device group and issue, a command to one storage device for the device group to end the busy condition.
