ABSTRACT:
A failure analysis system includes a controller A that sends a control command A, a looped interface A, the controller A being selectively connectable to the looped interface A, a node device A that is selectively connectable to the looped interface A, a node device B that is selectively connectable to the looped interface A, and an enclosure service device A that receives the control command A via the node device A. If a failure occurs, the enclosure service device A disconnects the node device B from the looped interface A, and one of: maintains the node device A connected to the looped interface A, and disconnects and subsequently re-connects the node device A to the looped interface A.
