Abstract: The present invention operates in a file server having a peripheral storage subsystem coupled thereto by means of a fibre channel. The file server includes an apparatus disposed between the file server and the storage subsystem for adapting fibre channel transmissions to and from an industry standard data bus of the file server. The apparatus includes a microprocessor executing a method comprising the following steps. Sensing if an interrupt has occurred by the file server, and if so, determining the condition of the interrupt by the file server and handling it. If an interrupt has not occurred, testing an interface between the fibre channel and the apparatus to assure connectivity of the fibre channel. Next, sense for an action to be taken in response to the interrupt, and if so attempt to take appropriate action.
