18 * Checks only for fatal/no/recover error.
19 * A detailed examination of the sense data is done later outside
20 * the interrupt handler.
22 * The logic is based on the 'IBM 3880 Storage Control Reference' manual
23 * 'Chapter 7. 9336 Sense Data'.
26 * dasd_era_none no error
27 * dasd_era_fatal for all fatal (unrecoverable errors)
28 * dasd_era_recover for all others.
