Abstract
Methods, systems and programs for isolating faults in a network loop are described. A single write and multiple read test is performed on the last device in a network loop to determine whether the link between the last device and the initiator is a faulty link. A multiple write test is performed on the last device to determine whether the loop segment between the initiator and the last device includes at least one faulty link. If a write error is identified, then the low level error counters of each network device are monitored. The network device with the updated error counter is identified such that the device before that network device in the network loop is selected as the first test device to be used in isolating a faulty link between the initiator and the last device.
