Ultra satan on a TT machine lun issues with the intern scsi

Postby simbo » Mon Oct 12, 2009 2:41 am

ive seen reports that the TT cant see the satandisk

i think you need to start the satandisk on an st or ste etc machine
and use jookies app for changing the lun id
to change it to lun 1 for its C and D scsi unitation
as i think the TT cant redirect its own scsi controller to use other than lun0 and its 5 devices

given this
you must if you want to say copy off the scsi drive to a satan card
and say use a muguk image from another places posts about this
then DISABLE boot from lun0 {the TT scsi}
or delete the driver on it
the card 'should' then take over
provided the driver on it can support boot from more than one lun
and im not sure icd pro can
hd driver can i know maybe if you have it
you can work a better route and post below

im helping frankb find the path
so yet to test this method
and its just my initial views
i dont know if the TT has tools or dip switch etc to change the internal scsi lun
or even if it matters
however im convinced it will in driver terms
so therfore it will in lun id
elfacto reverso you must change the satan disk id and use the driver to boot more than one lun
im sure others are beating a path
perhaps scsi tools 6.52 is the way..???

more on this

thinking further i feel using the U.S.D on id2 is the only way setting it first using an st/mega/x
if you use internal scsi but you cant i think boot a lun2 device using hddriver ?? not sure
if you dont use the TT

but i think lun 2 anyway is the most stable
with a tos/dos card
and first replace the driver on your internal scsi drive for a compatable to tos/windows partition type
... follow the guides to make a tos/dos compatable sdcard

not sure exactly what your trying to get across here, it might help if we clear up a few things...

the TT SCSI is completly independant from the ASCI bus, the device IDs are defined ACSI 0-7 and SCSI 0-7. ICD sees them as ID 0-15 with the TT SCSI controller on SCSI ID7 (15), HDDRIVER makes the definition by prefixing with a bus identifier eg 0.5 for ACSI ID5

you should avoid using the term LUN as this is only specific to the SCSI bus, as far as the atari is concerned LUNs are a mechanism to allow two or more devices on one SCSI ID usually shown as ID.LUN (eg 5.0, 5.1 etc), given we only use one device per ID the LUN is always 0

this is probably a bit confused because hddriver uses similar terminology to identify devices across the different buses (ACSI, SCSI & IDE)

anyway, back to the point in hand...

ultrasatan should show the two slots as ACSI ID0 and ID1, i think your trying to say if these are changed to ID2 & 3 it might help?

i would certainly try it but have nothing other than my TT to use it on so no way to change the satandisk settings.

jookie, whats your opinion on this?

i dont want to buy a ST just to change the ID but i'm sure i could post my US to someone and they do it for me

last i heard and read jookie is still working on a full fix
im sure it will get roled into any platform update
or be avalible as a seperate one
if i remember the scsi and asci posts have seperate layers so have different DMA
so have different LUN as far as the driver is concerted as it is in essence the scsi controller
and ide is a different layer becouse they all use there own drivers
so setting usd to other than 1/0 isnt the issue unless your internal scsi is using these for devices
i think you as i said just need to move them up one on the usd to avoid the conflict
you can just disconnect the internal drive and then use a boot disk to access the satandisk and move them
but ive read some of jookies others posts about it and he had to add a fix to the usd firmware

:cheers:

yes, both the asci and scsi use different dma channels, in fact iirc they have seperate dma controller ic's

as i mentioned using the term LUN is not a good idea, it's a SCSI term and should not be used in relation to atari ACSI/SCSI device numbering.

ACSI and SCSI IDs are completly independant from each other, you can mix ACSI and SCSI IDs in any combination and they wont cause a problem with each other. HDDRIVER uses [BUS.DEVICE] (eg 0.1 for SCSI ID 1), ICD uses 0-15 to represent SCSI ID 0-7 & ACSI ID 0-7

If changing the ASCI IDs of the ultrasatan does help the ultrasatan work on the tt it's more likley due to the changes in timing/signalling than ID conflicts

I've got this very problem on my TT and Ultrasatan. I've tried it with the LUNs set as shipped and also moved around, but still no luck on the TT. Occasionally I can see HDDRIVER detecting the Ultrasatan when it boots, but I can never seem to see it with device check in the HDDRIVER utility. I've got a SCSI to IDE/CF w/flash card interal on the TT that works fine, and I was hoping to use the Ultrasatan to transfer files back and forth to the TT.

This same Ultrasatan works fine on a standard ST.

we're in the same boat, i have internal CF via SCSI and was going to use the US to transfer to PC. If it works i might even try mounting the US inside the TT case.

anyway... jookie was looking into the problem after we exchanged a few PMs. I guess when/if he finds a solution he'll post on this forum somewhere.

Will removing the internal SCSI and hooking up ASCI - USD work?

no, scsi is not the problem... i believe it's an ACSI signalling issue

But of course... silly me.
They use different DMAs.
