>> scsi_cname (9) ( Solaris man: Ядро )

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[] = {
           "\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));
