摘要： A technique oversees a path between a multipathing driver of a host computer and a volume of a data storage array. The technique involves, while the multipathing driver of the host computer sends input/output requests (IOs) to the volume of the data storage array on the path, generating an IOs-Over-Period metric based on outcomes of the IOs, the IOs-Over-Period metric providing a measure of IOs per failure over a period of path operation. The technique further involves performing a comparison operation which compares the IOs-Over-Period metric to a predefined flaky path range having a predefined lower limit and a predefined upper limit. The technique further involves, after performing the comparison operation, outputting a detection signal indicating that the path is (i) flaky when the IOs-Over-Period metric falls within the predefined flaky path range and (ii) non-flaky when the IOs-Over-Period metric falls outside of the predefined flaky path range.

摘要： Systems and methods are provided for disabling an array port in an enterprise storage system. In one embodiment, a system comprises a storage area network (SAN), a plurality of hosts, an array controller comprising a plurality of array ports, and a management server. The management server receives a request to disable an identified one of the plurality of array ports and identifies, from a configuration table stored in the management system server, one or more of the plurality of hosts having at least one path to the identified array port. The management server transmits an instruction to the one or more of the plurality of hosts to disable paths to the identified array port.

摘要： A host computer accesses a federated storage volume at first and second frames (physical storage assemblies). The host identifies a preferred frame by (1) obtaining representative values of a performance metric for sets of paths to the volume, each set associated with a different frame, and (2) selecting the frame associated with the path set having the best representative value. In one example a response latency is used to detect different distances to the host and identify the closer frame, which will be preferred. Operating modes of the paths for non-preferred frames are set to “standby”. During subsequent operation using path selection to send storage operations to the volume, the host selects among paths in an “active” operating mode so as to access the volume at the preferred frame under normal operating condition. Standby paths are reserved for less normal operating conditions, such as when no active path is available.
摘要翻译： 主机在第一帧和第二帧（物理存储组件）访问联合存储卷。 主机通过以下方式来识别一个优选帧：（1）获得与该卷相对应的路径集合的性能度量的代表性值，每个集合与不同帧相关联，以及（2）选择与具有最佳代表值的路径集相关联的帧 。 在一个示例中，使用响应等待时间来检测与主机的不同距离并且识别更接近的帧，这将是优选的。 非首选帧的路径的操作模式设置为“待机”。 在使用路径选择将存储操作发送到卷的后续操作期间，主机以“主动”操作模式在路径之间进行选择，以便在正常操作条件下以优选帧访问卷。 待机路径被保留用于较不正常的操作条件，例如当没有活动路径可用时。
