 *
 * DESCRIPTION
 *   Checks only for fatal/no/recover error.
 *   A detailed examination of the sense data is done later outside

 *
 *   The logic is based on the 'IBM 3880 Storage Control Reference' manual
 *   'Chapter 7. 9336 Sense Data'.
 *
 * RETURN VALUES
 *   dasd_era_none	no error
 *   dasd_era_fatal	for all fatal (unrecoverable errors)
 *   dasd_era_recover	for all others.
