A scheduled or on-demand Fabric Manager discovery fails.   
    In the ViPR Controller UI under Fabric Managers the "Discovery Status" will show:   
     "Discovery failed reconciling FC endpoints for Network System: <URN>"   






Incomplete FCEndpoint entries exist in the ViPR Controller DB resulting in the failure.   
    These incomplete entries will be missing (key, value) pairings.   







      A solution exists for this issue, but intervention from Dell EMC technical support personnel is required. Support personnel must access your storage system to fix this issue.
