Disclosed is an on-line detection and fault isolation mechanism for a data transmission system (storage controller of any computer). It improves system availability by sorting errors according to their origin, priority, and weight, and by offering a degraded mode, where service is maintained in part of the transmission system (disabling and isolating the failing part).
