| 15 | * DASD_3370_ERP_EXAMINE | ||

| 17 | * DESCRIPTION | ||
| 18 | * Checks only for fatal/no/recover error. | ||
| 19 | * A detailed examination of the sense data is done later outside | ||
| 20 | * the interrupt handler. | ||
| 21 | * | ||
| 22 | * The logic is based on the 'IBM 3880 Storage Control Reference' manual | ||
| 23 | * 'Chapter 7. 3370 Sense Data'. | ||
| 24 | * | ||
| 25 | * RETURN VALUES | ||
| 26 | * dasd_era_none no error | ||
| 27 | * dasd_era_fatal for all fatal (unrecoverable errors) | ||
| 28 | * dasd_era_recover for all others. | ||
