# Short-Description: Start and stop the MD multipath monitor
# Description: The mdmpd service checks the status of all MD based multipath
#       devices on the system.  If a path to a device goes down, it removes
#       that path from the md multipath array.  It also periodically attempts
#       to contact the device via the down path.  When it succeeds repeatedly,
#       it re-adds the downed path to the multipath array.  There is a roughly
#       60 second delay between when a path becomes live again and when mdmpd
#       adds it back into service.
