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.
