Abstract
A method for detecting a failure in a serial topology. The method may comprise sending a predetermined pattern to a plurality of devices communicatively connected to an initiator in a serial topology; receiving a return result from each of the plurality of devices in response to the predetermined pattern; recognizing a problem associated with a particular device among the plurality of devices, the problem being recognized based on the return result from the particular device; sending a plurality of test patterns to the particular device; receiving a plurality of test results from the particular device in response to the plurality of test patterns; and determining a cause of the problem based on the plurality of test results, the cause of the problem being at least one of: a cable failure and a device failure.
