How to get rid of or remove the multipath device without rebooting the server, rescanning the scsi bus, or restarting multipathd

Solution Verified - Updated -


  • 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 ,
         [size=4.4T][features=1 queue_if_no_path][hwhandler=0][rw]
         \_ round-robin 0 [prio=0][enabled]
