A non-disruptive, on-line testing and switchover method and apparatus in a high availability, fibre channel switching environment. In a network having an active switching element (25), a redundant switching element (30) and a port (10), one aspect of the present invention provides for verifying a working data path (55) from the port to the redundant switching element, and thereafter verifying a working control path (75) to the redundant switching element. Both verification tests take place without interrupting operation on the network. In addition, another aspect of the present invention provides for recognizing a failure occurrence in the active switching element, and thereafter switching to the redundant switching element with the potential for minimal frame loss. |
