  • Automatic testing of redundant switching element and automatic switchover
    Patent number: 6643602
    Abstract: 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, a redundant switching element and a port, one aspect of the present invention provides for verifying a working data path from the port to the redundant switching element, and thereafter verifying a working control path 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.
    Type: Grant
    Filed: October 29, 2002
    Date of Patent: November 4, 2003
    Assignee: Mcdata Corporation
    Inventors: Samuel C. Lay, Jeffrey J. Nelson, James Rodgers, Kenneth N. Jessop
