Abstract: Method and system for managing error related events while a system is processing input/output (“I/O”) requests for accessing storage space is provided. Various components are involved in processing the I/O requests. Some of these components may also have sub-components. Events related to the various components are classified with respect to their severity levels. Threshold values for a frequency of these events is set and stored in a data structure at a memory location. When an event occurs, the severity level and the threshold value for the event are determined from the data structure. The actual frequency is then compared to the stored threshold value. If the threshold value is violated and there is an alternate path to route the I/O request, then the affected component is restricted and the alternate path is used to route the I/O request.

Abstract translation: 提供了在系统处理输入/输出（“I / O”）请求访问存储空间时管理错误相关事件的方法和系统。 处理I / O请求涉及各种组件。 这些组件中的一些也可以具有子组件。 与各种组件相关的事件根据其严重性级别进行分类。 这些事件的频率的阈值被设置并存储在存储器位置的数据结构中。 当事件发生时，事件的严重性级别和阈值由数据结构确定。 然后将实际频率与存储的阈值进行比较。 如果违反了阈值，并且存在路由I / O请求的备用路径，则受影响的组件受到限制，并且备用路径用于路由I / O请求。
