AI Technical Summary
Technical Problem
In storage systems, a major system failure or crash of the main controller may cause the fans to stop spinning, thus affecting the stability of the storage system.
Method used
By monitoring the PWM signal of the lower controller through the CPLD, the fan control scenario is determined and the corresponding PWM signal is output to control the fan rotation and prevent it from stopping.
Benefits of technology
It improves the stability of the storage system, prevents the fan from stopping due to abnormal conditions, and ensures continuous heat dissipation.

Abstract
The application provides a fan stall repair method, system, device and medium, the method comprises the following steps: determining whether the current fan control scene belongs to the first fan control scene according to the received target signal; in the case of determining that the current fan control scene belongs to the first fan control scene, determining the control type of the controller; in the case of determining that the control type of the controller is the down control controller, monitoring the received PWM signal issued by the monitoring control module in the fan control link corresponding to the down control controller for a preset time length, and obtaining a monitoring result; according to the monitoring result, output the PWM signal corresponding to the monitoring result to control the fan. The purpose is to improve the system stability.
