 * 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.
