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

NAME
scsi_find_sense_descr - find descriptor in SCSI sense data SYNOPSIS
#include <sys/scsi/scsi.h> uint8_t *scsi_find_sense_descr(uint8_t *sense_buffer, int sense_buf_len, int req_descr_type); INTERFACE LEVEL
Solaris DDI specific (Solaris DDI). PARAMETERS
sense_buffer Pointer to a buffer containing SCSI descriptor sense data. The data is expected in wire format starting at the response code. sense_buf_len Integer that contains the length of sense buffer in bytes. req_descr_type Integer that contains the descriptor type value for the desired sense descriptor. DESCRIPTION
The scsi_find_sense_descr() function is used to obtain a pointer to a specific descriptor type, specified by req_descr_type, within a descriptor sense buffer. Before returning the pointer, scsi_find_sense_descr() verifies that the entire descriptor is present based on the length provided in sense_buf_len. Any value for req_descr_type can be requested. The following descriptor types are already defined: #define DESCR_INFORMATION 0x00 #define DESCR_COMMAND_SPECIFIC 0x01 #define DESCR_SENSE_KEY_SPECIFIC 0x02 #define DESCR_FRU 0x03 #define DESCR_STREAM_COMMANDS 0x04 #define DESCR_BLOCK_COMMANDS 0x05 #define DESCR_OSD_OID 0x06 #define DESCR_OSD_RESP_INTEGRITY 0x07 #define DESCR_OSD_ATTR_ID 0x08 Drivers should use scsi_validate_sense(9F) to ensure that the sense buffer contains valid descriptor sense data. RETURN VALUES
The scsi_find_sense_descr() function returns a pointer to a sense descriptor of the requested type if a descriptor of that type exists. If no such descriptor exists, scsi_find_sense_descr() returns NULL. CONTEXT
The scsi_find_sense_descr() function can be called from user or interrupt context. SEE ALSO
