TEAC SCSI EXERCISER TODO July 2/91
TSX.todo
Things to add
-------------
1) Read Sector n
2) Write test sector
3) Read & compare test sector
4) Requestor for SCSI_CMD & IO Req Blk
5) Try all SCSI IDs
6) Support A2090(A) Unit # weirdness.
;-----------------
; UNIT NUMBERS
; Unit numbers to the OpenDevice call have encoded in them which
; SCSI device is being referred to. The three decimal digits of
; the unit number refer to the SCSI Target ID (bus address) in
; the 1's digit, the SCSI logical unit (LUN) in the 10's digit,
; and the controller board in the 100's digit.
;
; Examples:
; 0 drive at address 0
; 12 LUN 1 on multiple drive controller at address 2
; 104 second controller board, address 4
; 88 not valid: both logical units and addresses
; range from 0..7.
;
; CAVEATS
; Original 2090 code did not support this command.
;
; Commodore 2090/2090A unit numbers are different. The SCSI
; logical unit is the 100's digit, and the SCSI Target ID
; is a permuted 1's digit: Target ID 0..6 maps to unit 3..9
; (7 is reserved for the controller).
;
; Examples:
; 3 drive at address 0
; 109 drive at address 6, logical unit 1
; 1 not valid: this is not a SCSI unit. Perhaps
; it's an ST506 unit.
;
; Some controller boards generate a unique name (e.g. 2090A's
; iddisk.device) for the second controller board, instead of
; implementing the 100's digit.
;-----------------
7) Support A2090 Write bug
8) The impression I get looking at your Logs is that there is at once
too much & too little information. A useful exerciser needs to
interpret the data more. Perhaps have some switches for the amount of
info to present. ie. a lot of the buffer dumps are useless.
9) I have to fix up the Mode_sense interpretations.
10) I have to add to the docs. Mention that some functions MEDIUM TYPES
and GET DEFAULTS for eg. are aimed at the FC-1.
11) Add how to get started, ie setting up SCSI ID, LUN, DEVICE for the
complete novice.
x) Your suggestions?
