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));
