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
       The  scsi_cname()  function  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.

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

       The scsi_mname() function decodes SCSI messages.

       The scsi_rname() function decodes packet completion reasons.

       The scsi_sname() function 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, interrupt, or kernel context.

EXAMPLES
       Example 1 Decoding SCSI tape commands.

       The scsi_cname() function 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));
