* DESCRIPTION
|
2006-06-29 08:58:12 -04:00
|
|
|
* Checks only for fatal/no/recover error.
|
2005-04-16 18:20:36 -04:00
|
|
|
* 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'.
