Issue

• Unable to remove the multipath device after unmapping the LUN from the server.

• Attempting to flush a multipath map with "multipath -f" or "multipath -F" results in "map in use":

       # multipath -f mpath7
       mpath7: map in use
  

• The multipath command still shows the multipath device, with path(s) to the unmapped LUN as follows:

       # multipath -ll mpath7
       mpath7 (36090a01870982994dcb8d4405ed03cbf) dm-7 ,
