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[] = {
            "\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));	
    ..
