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);

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.

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)); ..
