scsi_asc_key_strings(9S)				    Data Structures for Drivers 				  scsi_asc_key_strings(9S)

NAME

       scsi_asc_key_strings - SCSI ASC ASCQ to message structure

SYNOPSIS

       #include <sys/scsi/scsi.h>

INTERFACE LEVEL

	Solaris DDI specific (Solaris DDI).

DESCRIPTION

       The scsi_asc_key_strings structure stores the ASC and ASCQ codes and a pointer to the related ASCII string.

STRUCTURE MEMBERS

       ushort_t asc;	       /* ASC code */
       ushort_t ascq;	       /* ASCQ code */
       char    *message;       /* ASCII message string */

       asc		 Contains the ASC key code.

       ascq		 Contains the ASCQ code.

       message		 Points to the NULL terminated ASCII string
			 describing the asc and ascq condition

NAME

       scsi_validate_sense - find descriptor in SCSI sense data

SYNOPSIS

       #include <sys/scsi/scsi.h>

       int scsi_validate_sense(uint8_t *sense_buffer, int sense_buf_len,
	    int *flags);

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.

       sense_buf_len	Length of sense buffer in bytes.

       flags		Returns additional properties of the sense data.

DESCRIPTION

       The  scsi_validate_sense() function returns the format of the sense data contained in the provided sense buffer. If the response code field
       in the sense data is not recognized or if there is not enough sense data to include sense key, asc,  and  ascq  then  scsi_validate_sense()
       returns	SENSE_UNUSABLE.  If  the buffer contains usable sense data in fixed format, the function returns SENSE_FIXED_FORMAT. If the buffer
       contains usable sense data in descriptor format, the function returns SENSE_DESCR_FORMAT.

       The following flags may be set as appropriate depending on the sense data:

       SNS_BUF_OVERFLOW    The sense data buffer provided for the request is too small to hold all the sense data.

       SNS_BUF_DEFERRED    The sense data contained in the buffer relates to an error that has occurred during the processing  of  a  successfully
			   completed command, such as a cached write that could not be commited to the media.

RETURN VALUES

       SENSE_UNUSABLE	     The response code from the sense data is unrecognized or not enough sense data present to provide the sense key, asc,
			     and ascq.

       SENSE_FIXED_FORMAT    The sense data in the buffer is in "fixed format".

       SENSE_DESCR_FORMAT    The sense data in the buffer is in "descriptor format".

CONTEXT

       The scsi_validate_sense() function can be called from user or interrupt context.
