Matthew,
Here are short and long lists that I dug up from
sg3_utils and lsscsi. The long list should adhere
to the SPC-4 pdt names more closely:
static const char * scsi_pdt_strs[] = {
/* 0 */ "disk",
"tape",
"printer",
"processor", /* often SAF-TE (seldom scanner) device */
"write once optical disk",
/* 5 */ "cd/dvd",
"scanner",
"optical memory device",
"medium changer",
"communications",
/* 0xa */ "graphics [0xa]",
"graphics [0xb]",
"storage array controller",
"enclosure services device",
"simplified direct access device",
"optical card reader/writer device",
/* 0x10 */ "bridge controller commands",
"object based storage",
"automation/driver interface",
"0x13", "0x14", "0x15", "0x16", "0x17", "0x18",
"0x19", "0x1a", "0x1b", "0x1c", "0x1d",
"well known logical unit",
"no physical device on this lu",
};
static const char * scsi_short_device_types[] =
{
"disk ", "tape ", "printer", "process", "worm ", "cd/dvd ",
"scanner", "optical", "mediumx", "comms ", "(0xa) ", "(0xb) ",
"storage", "enclosu", "sim dsk", "opti rd", "bridge ", "osd ",
"adi ", "(0x13) ", "(0x14) ", "(0x15) ", "(0x16) ", "(0x17) ",
"(0x18) ", "(0x19) ", "(0x1a) ", "(0x1b) ", "(0x1c) ", "(0x1e) ",
"wlun ", "no dev ",
};
There are no known unknowns ...
