NAME

       scsi_cname, scsi_dname, scsi_mname, scsi_rname, scsi_sname - decode a SCSI name

SYNOPSIS

       #include <sys/scsi/scsi.h>

       char *scsi_cname(uchar_t cmd, char **cmdvec);

       char *scsi_dname(int dtype);

       char *scsi_mname(uchar_t msg);

       char *scsi_rname(uchar_t reason);

       char *scsi_sname(uchar_t sense_key);

INTERFACE LEVEL

       Solaris DDI specific (Solaris DDI).

PARAMETERS

       cmd	       A SCSI command value.

       cmdvec	       Pointer to an array of command strings.

       dtype	       Device type.

       msg	       A message value.

       reason	       A packet reason value.

       sense_key       A SCSI sense key value.

DESCRIPTION

       scsi_cname()  decodes SCSI commands. cmdvec is a pointer to an array of strings. The first byte of the string is the command value, and the
       remainder is the name of the command.

       scsi_dname() decodes the peripheral device type (for example, direct access or sequential access) in the inquiry data.

       scsi_mname() decodes SCSI messages.

       scsi_rname() decodes packet completion reasons.

       scsi_sname() decodes SCSI sense keys.

RETURN VALUES

       These functions return a pointer to a string. If an argument is invalid, they return a string to that effect.

CONTEXT

       These functions can be called from user or interrupt context.

EXAMPLES

       Example 1: Decoding SCSI tape commands.

       scsi_cname() decodes SCSI tape commands as follows:

       static char *st_cmds[] = {
		   "00test unit ready",
		   "01rewind",
		   "03request sense",
		   "10read",
		   "12write",
		   "20write file mark",
		   "21space",
		   "22inquiry",
		   "25mode select",
		   "31erase tape",
		   "32mode sense",
		   "33load tape",
		   NULL
	   };
	   ..
	   cmn_err(CE_CONT, "st: cmd=%s", scsi_cname(cmd, st_cmds));
	   ..
