scsi_sense_key(9F) Kernel Functions for Drivers scsi_sense_key(9F) NAME
scsi_sense_key, scsi_sense_asc, scsi_sense_ascq - retrieve fields from SCSI sense data SYNOPSIS
#include <sys/scsi/scsi.h> uint8_t scsi_sense_key(uint8_t *sense_buffer); uint8_t scsi_sense_asc(uint8_t *sense_buffer); uint8_t scsi_sense_ascq(uint8_t *sense_buffer); INTERFACE LEVEL
Solaris DDI specific (Solaris DDI). PARAMETERS
sense_buffer Pointer to a buffer containing SCSI sense data. The sense data is expected in wire format starting at the response code. It can be in either fixed or descriptor format. DESCRIPTION
The scsi_sense_key() function returns the sense key value from the sense data contained in the sense_buffer. The scsi_sense_asc() function returns the additional sense code (ASC) value from the sense data contained in the sense_buffer. The scsi_sense_ascq() function returns the additional sense code qualifier (ASCQ) value from the sense data contained in the sense_buffer. The scsi_sense_key(), scsi_sense_asc(), and scsi_sense_ascq() functions are used to retrieve values from SCSI sense data, regardles of whether the sense data is in fixed format or descriptor format. Drivers should use scsi_validate_sense(9F) to ensure that valid sense key, asc, and ascq values are present in the sense data. RETURN VALUES
The scsi_sense_key() function returns the sense key value from the sense buffer. The scsi_sense_asc() function returns the additional sense code (ASC) from the sense buffer and the scsi_sense_ascq() function returns the additional sense code qualifier (ASCQ) from the sense buf- fer. CONTEXT
The scsi_sense_key(), scsi_sense_asc(), and scsi_sense_ascq() functions can be called from user or interrupt context. SEE ALSO
