| * 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. |
