SCSI_CNAME(9F)SCSI_CNAME(9F)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 exam‐
ple, 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[] = {
"\000test unit ready",
"\001rewind",
"\003request sense",
"\010read",
"\012write",
"\020write file mark",
"\021space",
"\022inquiry",
"\025mode select",
"\031erase tape",
"\032mode sense",
"\033load tape",
NULL
};
..
cmn_err(CE_CONT, "st: cmd=%s", scsi_cname(cmd, st_cmds));
