The problem is that your disk doesn't claim to be either SCSI-1 or
SCSI-2, and the scsi driver won't assign a device it can't get a
version on. My 4-year-old Fujitsu MO drive does the same thing, even
though the documentation claims it's SCSI-2 compliant.
My solution was to edit /sys/scsi/scsiconf.c (search for SID_ANSII),
and just make the
if ((inqbuf->version & SID_ANSII) > 0) {
line say
if (1) {
. That'll force it to assign devices with no SCSI version.
