+ * DASD_9336_ERP_EXAMINE 
+ *
+ * DESCRIPTION
+ *   Checks only for fatal/no/recover error. 
+ *   A detailed examination of the sense data is done later outside
+ *   the interrupt handler.
+ *
+ *   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.
