|
* 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.
