If memory serves, the FC drivers take the results from loop/fabric 
discovery and then map each discovered device to a target_id. During 
boot, the driver stalls/sleeps waiting for discovery to complete before 
completing to the CAM. Later on if the loop/fabric changes, the user 
would need to force a re-scan to pick up the new devices.
