- 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?
