摘要： An improved technique for handling events in a multipathing driver employs an event queue and a queue manager that run in the kernel of a computing system. The queue manager receives events raised by the multipathing driver, as well as events raised by software constructs, such as application programs. Records of events are added to the event queue in the order the queue manager receives them. Event records may be consumed chronologically by external software. Preferably, the event queue is sufficiently large to store all events arising out of most predicted fault scenarios. Also, the queue manager is sophisticated and can perform certain diagnostic and analysis tasks without the aid of external software.

摘要： An improved technique for managing access to performance data of a kernel driver includes acquiring performance data in the kernel driver over identified intervals of time marked by the kernel driver itself and transferring the performance data to a persistence manager outside the kernel, where client applications can access the performance data and/or post-processed versions thereof without disturbing the operation of the kernel driver.

摘要： In large complex multi-path storage environments, knowing there is a problem is extremely valuable. Example embodiments of the present invention include a management framework that provides an easy to use and read graphical perspective that allows analysis of faults in a multi-path storage environment. The architecture is not only responsive, scalable, and robust, but also provides “middleware” services to a broad spectrum of enterprise management applications whose domains may extend beyond storage path management. The management framework includes a consolidator that, along with an agent on the hosts, supports an administrator in: collecting storage path information from hosts; summarizing, aggregating, filtering, and reformatting storage path information to serve enterprise management needs and policies; forwarding an alert regarding storage path information to interested managers; routing storage path management commands from managers to hosts; and reporting command completion status from the host back to the requesting manager.

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.
