When a request is issued, the CD-ROM Device Manager will set the IORB_REQ_STATUSBLOCK bit in the RequestControl field of the IORB header. If this bit is set and an error occurs, the Adapter Device Driver must return a valid status block and a valid sense data block back to the Device Manager when the request completes.
The status block is pointed to by the pStatusBlock field in the IORB header. It should be noted that pStatusBlock is a 16 bit near pointer, so the block is within the same segment as the IORB. The sense data is pointed to by the SenseData field in the status block. This field is a 16:16 far pointer. The length of the sense data to return is in specified in the ReqSenseLen field.
The adapter device driver must set the following fields when returning sense data:
To maintain consistency with the adapter device driver specification, an IORB error code must also be returned in the IORB header when an error occurs. This is in addition to the returned sense data information. The table below shows the mapping between Sense Data error codes and IORB error codes. If the Adapter Device Driver returns Sense Key and Sense Codes listed in the SCSI-2 specification which are not listed in the table below, the adapter device driver must map the sense key and codes to the most appropriate IORB error code.
