PARAMETERS

33       cmd          A SCSI command value.
34
35
36       cmdvec       Pointer to an array of command strings.
37

41
42       msg          A message value.
43
44

DESCRIPTION

52       The scsi_cname() function decodes SCSI commands. cmdvec is a pointer to
53       an array of strings. The first byte of the string is the command value,
54       and the remainder is the name of the command.
55
56
57       The scsi_dname() function decodes the peripheral device type (for exam‐
58       ple, direct access or sequential access) in the inquiry data.
59
60
61       The scsi_mname() function decodes SCSI messages.
62
63
64       The scsi_rname() function decodes packet completion reasons.
65
66
67       The scsi_sname() function decodes SCSI sense keys.
68

RETURN VALUES

70       These  functions  return  a  pointer  to  a  string.  If an argument is
71       invalid, they return a string to that effect.
72

CONTEXT

74       These functions can be called from user, interrupt, or kernel context.
75

EXAMPLES

77       Example 1 Decoding SCSI tape commands.
78
79
80       The scsi_cname() function decodes SCSI tape commands as follows:
81
82
83         static char *st_cmds[] = {
84                     "\000test unit ready",
85                     "\001rewind",
86                     "\003request sense",
87                     "\010read",
88                     "\012write",
89                     "\020write file mark",
90                     "\021space",
91                     "\022inquiry",
92                     "\025mode select",
93                     "\031erase tape",
94                     "\032mode sense",
95                     "\033load tape",
96                     NULL
97             };
98             ..
99             cmn_err(CE_CONT, "st: cmd=%s", scsi_cname(cmd, st_cmds));
