Abstract
A method and apparatus for determining proper cabling and identical device locations between two controllers in a RAID system. Each controller first obtains the port names to which it is attached. The list is then reviewed to determine that there are no duplicate entries. Once this step is completed, the controllers exchange their port name lists. The lists are compared to make sure they exactly match. Finally, the controllers exchange a map of the devices themselves present on two channels. The exchange device maps are compared and must be equal. The two device maps being equal indicate that each storage device is logged on to the network through both I/O ports and is available to each controller.
