SCSI_CNAME(9F) Kernel Functions for Drivers 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

illumos DDI specific (illumos 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[] = {
"\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));
