My copy of SCSI-2 is draft 10b from 1989 and it doesn't have a
section 8.2.5.1 . Since SCSI-2 was withdrawn over 10 years
ago perhaps you could use a more recent reference. [I see
webstore.ansi.org still sells the SCSI-2 standard for $30 .]

SPC-3 is a standard [ANSI INCITS 408-2005; ISO/IEC 14776-453]
and the relevant section, judging from its last draft, would
be table 83 in section 6.4.2 . And it is now called the
"peripheral device type".
