  • Failure detection and isolation
    Patent number: 6430714
    Abstract: A method for detecting faulty equipment on a loop of disk drives in which error counts are obtained for each disk drive including an amount of invalid transmission words and/or a count of loop initialization protocols (LIPs) that have been initiated and received. Counts are obtained twice so as to detect changes to the error counts. Based on the error counts and LIP counts suspect disk drives may be recorded along with their electrical predecessor on the loop to permit expedited identification of faulty equipment.
