The SIOC_XSENSE ioctl returns detailed information about device status and errors when such informa-

tion is available. Since there have been multiple versions of the SCSI standard for sense (status) data, mul-

tiple versions of the sense data declaration are provided. The SCSI-1 and non-aligned versions are pro-

vided for backward compatibility only. If no new CHECK-CONDITION-caused REQUEST SENSE com-

mand data has been obtained since the last

SIOC_XSENSE ioctl call, the

xsense_aligned.error_class

and sense_2_aligned.error_code

ﬁelds will contain the

value zero. Applications which require more accurate REQUEST SENSE data handling should use the

SCSI device-control driver (see scsi_ctl(7)).

The following information is included from <

sys/scsi.h>:

#define SIOC_XSENSE _IOR(’S’, 7, union sense_data)

/* structure for SIOC_XSENSE ioctl */

union sense_data {

struct xsense_aligned r_sense1a; /* SCSI and CCS devices */

struct sense_2_aligned r_sense2a; /* SCSI-2 devices */

};

/* structure for SCSI-1 and SCSI-CCS sense data */

struct xsense_aligned {

unsigned int valid:1;

unsigned int error_class:3;

unsigned int error_code:4;

unsigned char seg_num;

unsigned int parms:4;
