There are two conditions for ATA pass thru command that falls into
'SRB_STATUS_ERROR' condition.
1. When the "CC" bit is set by the host in ATA pass-through CDB
- Even for the successful completion, SCSI target shall generate
check condition.
- Driver returns a result code of SAM_STAT_CHECK_CONDITION, with a
driver byte of DID_OK to the mid layer.
Below is the snippet of existing code which fills a result code
of SAM_STAT_CHECK_CONDITION:
***********************************
if (le32_to_cpu(srbreply->scsi_status) == SAM_STAT_CHECK_CONDITION) {
int len;
scsicmd->result |= SAM_STAT_CHECK_CONDITION;
..........
************************************
2. When the "CC" bit is reset by the host and if SCSI target generates
a check condition when an error occurs.
- Driver returns a result code of SAM_STAT_CHECK_CONDITION, with a
driver byte of DID_ERROR to the mid layer.
