P2000 San Mappings

Hi we have a P2000 SAN that consists of 2 Controllers with 3 to 4 volumes on each controller. We also have multiple hosts listed under the host section. We are trying to remove some older hosts that are no longer connected. The host cannot be removed because it states that it is currently mapped.  Under the host's mappings 8 volumes are listed 3 of which say Not-mapped the other 5 say Explicit No-Access. When clicking on a volume in the port map with explicit no-access and check the box that says clear mappings the server will then suddenly show a default map on one of the other volumes. When checking the box Clear mapping shouldn't the host default to un-mapped?  Also what is the difference between default map and explicit mapping?  Why not just use one or the other?

 

Thanks,
