Two Switches Show on my Map, But I Only Have One Switch

If two switches show on your map, but you only have one switch, it may be that you have two switches in a non-contiguous VSAN have the same Domain ID. Fabric Manager uses <vsanId><domainId> to look up a switch, and this can cause the fabric discovery to assign links incorrectly between these errant switches.

The workaround is to verify that all switches use unique domain IDs within the same VSAN in a physically connected fabric. (The fabric config checker will do this task.)
