Return_Values

   Upon successful completion, the mrd_startup(3mrd) and mrd_
   shutdown(3mrd) functions return the value MRD_STATUS_SUCCESS.
   If the mrd_startup(3mrd) fails the returned status value will be
   set to one of the following values. Other values that correspond
   to specific SCSI errors may also be possible, but these are the
   most likely.
