Sounds like it's at the same SCSI id as something else on the bus.
Make sure you give everything it's own id. Id's can be from 0 to 7 and
the gvp board is probably at id 7, so make your disks id's 0 and 1.

4666.2 | Tried different addresses | DECWET::DAVIS | Strength through Peace | Sun Apr 07 1991 18:00 | 4 |
| I tried different addresses(1-6) with the same effect. I am checking
my cable continuity now.

| Is the drive you are trying to add one of the DEC RZ series? I recall
some mention of these working only while alone on the bus until after
formatting...

You may be thinking of 4564.12 ?

| Have your terminating resistor packs set correctly on each of the
drives?

4666.6 | Probable termination probs | DECWET::DAVIS | Strength through Peace | Mon Apr 08 1991 13:34 | 4 |
| I believe I *am* having a termination problem. I am going to
internally and externally terminate the drive(s).

re .6
The correct way to terminate the SCSI bus is to have the
GVP controller on one end of the cable ( the controller terminates
one end of the bus ). Then have termination resistors in the last drive
on the SCSI bus. No other termination.

4666.8 | put rz23 on card | SALEM::LEIMBERGER | | Tue Apr 09 1991 06:29 | 8 |
| I stated in another note that I had similar problems,and I found that
if I put the RZ23 on the card,and the quantum at the end of the cable I
had no problems. I can't explain this but I tried several different
approaches,and two RZ23 drives. It did not matter until I traded in my
older GVP controller for the latest version. I was going along fine
until I swapped controllers. My next effort will be to exchange the
quantum for an RZ23,and see if two will run.

| RE: .8
Possibly the Quantum has the terminating resistor pack and the RZ
doesn't.

4666.10 | termination no prob now | CRISTA::LEIMBERGER | I have my marbles now I want yours | Tue Apr 09 1991 10:40 | 10 |

Not so. I tried several combinations with, and without the terminating
packs. As I am runnung now RZ on card quantum on cable no packs no problem.
GVP said that it waould be fine. However I used to have it the other way
around with the old controller,and I had to have the RZ terminated. What would
happen if it wasen't was that when I ran Fasstprep it showed as a dec drive
size etc. but when you actually went to perform the software would hang,and the
drive light would come on and stay on.

4666.11 | NEED HELLLLLLP.
| PAMSRC::63653::BARRETT | Tar is not a plaything | Wed Jul 10 1991 13:21 | 9 |
| I'm also having this problem (no DEC drives involved though), and I suspect
in my case its the SCSI ID setting. Anyone know how to change the SCSI ID of
a Quantum 100meg drive to 1? I have no docs.
THANKS!

Quantum drives have three address jumpers, which usually come set to
address #6. I have no docs either, so I inferred what I could from
what little I knew and it worked. Change 110 to 001 and try again.
