Path dynamic detection method and device and equipment

Abstract

The invention discloses a path dynamic detection method and device, equipment and a computer readable storage medium. The method comprises the steps that each designated transmission path is detectedto obtain a corresponding detection result; whether the detection results indicate that all the transmission paths are in a normal working state is judged; if yes, the sum of a current time interval and a preset time interval is determined as a current time interval; if not, a preset minimum time interval is determined as a current time interval, wherein the initial value of the current time interval is the minimum time interval; and the step of detecting each designated transmission path is returned to and executed after the current time interval from the moment when the detection results areobtained. Through the path dynamic detection method and device, the equipment and the computer readable storage medium, resource waste can be avoided to some extent, and abnormal path repair conditions can be known in time.

Description

technical field [0001] The present invention relates to the technical field of transmission path detection, and more particularly, to a path dynamic detection method, apparatus, device, and computer-readable storage medium. Background technique [0002] In an enterprise-level application system, an application server for processing business requests and a storage system are connected to each other through a storage network (SAN). In order to avoid a single point of failure and improve system reliability and IO throughput, multi-path IO access (MPIO) is usually used between the application server and the devices in the storage system. like figure 1 As shown, the application server (Host) is connected to a dual-controller storage device (storage) through two SAN switching networks (SAN Switch 0 and SAN Switch 1), and a total of four physical paths from the application server to the storage device are implemented. With the help of multipath disk drivers, application servers c...

Problems solved by technology

Among them, when the path detection task is started at regular intervals, the time interval between every two adjacent detections is the same, that is, no matter what state the path is in, the detection is performed at a fixed time interval, and multiple consecutive detection result paths are prone to appear. All are in normal working state, resulting in waste of resources or failure to be detected in time when the faulty path has been repaired.
