Return_Values

   Upon successful completion, the mrd_inject(3mrd) function returns
   the value MRD_STATUS_SUCCESS. If the mrd_inject(3mrd) fails the
   returned status value may 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.
