Abstract
According to the invention, techniques for detecting and recovering from errors occurring in disk drive subsystems having a controller and drive units connected by a fiber channel loop. Specific embodiments can provide storage subsystems, methods and apparatus for use in information processing environments, for example. Embodiments can determine when each drive is disconnected from the loop in the external storage subsystem structured by using the FC Loop, and thereupon, the FC Loop can be controlled by bridging the communication path using the PBC so that the loop is not broken.
