- Hi there,
- I hope some of you know, what is going on with SCSI-Streamers for the
- A3000. I have some Problems, here they are:
- I got the following Streamer:

- I don't know, what all of this means, but maybe you do just perfectly and
- can see the Problem right here. It's a 150 Meg QIC tape streamer.
- First of all I tried to back up with BRU. The Entries for the tape in
- BRUTab look like this:
- ---
- tape: \
- size=0 seek=0 bufsize=200K noreopen rewind \
- prerr=5 pwerr=5 zrerr=5 zwerr=5 frerr=5 fwerr=5 wperr=30 \
- advance tape rawtape device=scsi.device unit=4
- ntape: \
- size=0 seek=0 bufsize=200K noreopen norewind \
- prerr=5 pwerr=5 zrerr=5 zwerr=5 frerr=5 fwerr=5 wperr=30 \
- advance tape rawtape device=scsi.device unit=4
- ---
- seems to be the standart. None of my Problem is solved by just using a
- fixed tapesize or buffersize.
- The PROBLEM is the following: i start out to save with bru -cvvf tape:, so
- my comp fills up the 200K Buffer and then starts writing to tape - then he
- does the second Buffer and so on. But suddenly he just stops with the drive
- LED burning and not doing anything any more. Sometimes the drive I tried to
- backup is not validated any more. This was some months ago. Now he doesn't
- seem to get any further than the first block, then he stops, but the other
- tasks are still working all right.
-
- You could think one of the following could be the PROBLEM:
- - wrong termination:
- with the Mac(actually the streamer is for a Mac) we always back up
- without any problems. First I have tried just the regular termination
- everyone would think of: the tape is external and the last one on the bus
- so it's terminated. Then I tried it with a special terminator for the
- Mac2fx, I tried internal termination, external - just everything - and it
- seems that that's not the problem.
- - software:
- i tried several software packages not only my own but also my friend's.
- some tape-handler in connection with tar or gnutar, Quarterback 5.02,
- gvp-Tapestore and so on - always the same problem.
-
- some other observations I made:
- - I can read from the tape no problem. For example I managed to backup a
- tiny part of my drive and could always restore it.
- - tools like tape and magtape work no problem, well, magtape always
- returned "Unit not ready, scsi status is 2" when invoking it the first
- time - the second time there never is a problem.
- - with my old Amiga 2000 and a Golem SCSI-II Controller everything just
- worked fine.
- - inquirepage just used for unit 4 brings up the list at the top of this
- message and then hangs after writing "Inquire Page 0x02 error code 5
- (0x05) Illegal Request" quite a few times.
-
- That's it. I think you got my problem, so if you know anything to fix this,
- please let me know.
- Thanks in advance,
- Rudy
