o  robot_name - The name of the robot device to be opened. On
       Digital UNIX, if the leading character of the name is not a
       slash (/), /dev/ will be prepended to the name.

    o  robot_info - This is the address of the robot_info_t structure
       when mrd_startup is called. This data structure contains the
       element starting address and counts for each type of element,
       which are needed to map an absolute element to the correct
       zero relative address and type.

    o  log_info - This is a character array that should be at least
       MRD_MAX_LOG_STRING in length. If this function fails as the
       result of a SCSI error, this will be filled with the formatted
       request sense data. If this function fails as the result
       of an operating system error, the operating system message
       particular to the error will be copied into the array.
