My explanation here may have been too sketchy.
Suppose your SCSI card BIOS shows during boot
SEAGATE Model: ST39173LW Rev: 6246
or something that effect and you want to make sure that
no non-zero LUN probe is done against this drive, then
{"SEAGATE", "ST39173LW", "6246", BLIST_NOLUN},
needs to be added to the device_list[] (in 2.x.1xx, 2.2.xxx, it could
be a different name in 2.0.3x).
SCSI driver prints the device info in the following manner, so
it is easier to figure out which part is which.
Example:
Vendor: ULTIMA Model: AT3 Rev: 1.90
Type: Scanner ANSI SCSI revision: 02
In some cases, model field contains one or more blanks and some
more non-blank characters, and you must put int the string literally.
I have forgotten exactly how I learned this.
But I remember reading the code for blacklisting in 2.0.xx version
since I needed to make the Empire 1040 disk going in my home PC
with Tekram DC390 a year or so ago (or it was when
I used the same disk with AHA1542CF earlier).
It still is "RTFM", hmm, I should phrase this "Read The Source" instead.
I think it is about time someone wrote the
clear and detailed logical view and overall scheme used
in the SCSI subsystem including these blacklisting using
device_list[]. It would help the future SCSI board driver writes,
users and integrators alike. But who?
In any case, I am sure SCSI gurus on this list would help if questions arise
concerning device_list[].
