| The SCSI drive will only boot if the ST-506 drive does not (non
bootable or not there). Yes it must be DH3 which is not the same as
SCSI I.D. which could be 0 AND EQUAL to your mountlist entry.
Make sure you make a small partition at the beginning (2-3 cylinders)
because this first partition is mounted automaticly by the 2090A and
will be in the OFS (slow file system). The rest of the drive can be
mounted in your startup or with the mount command in a CLI. All
partitions must be formatted before use and must agree with your
mountlist entry for each partition.

Thanks for the reply Jean, so are you saying it should be DH3: not DH2: but my
scsi number can be any id 0-6 in my mounlist and on the drive?
Also how about the settings of the other switches on the rz23 4, 5 and 6.
Anyone any suggestions?

| 4891.3 | Read the manual first | KAOFS::J_DESROSIERS | Lets procrastinate....tomorrow | Tue Jul 16 1991 13:24 | 7 |
| Check out note 2610.* I had some performance problems with a SCSI
drive on the 2090A untill I read the manual and did what it instructed
to do.

| Looks like you had some fun in note 2610. I am not having performance problems,
I just don't seem to be talking to the drive at all so wanted to know that all
my jumper, mountlist settings are ok before I start on the suspecting hardware
faults. When I try to prep the drive, it thinks about it, then I get a prep
failed message. I have tried another rz23 that did the same thing so I think
I may have a problem with the cable/2090a.

| If the cable is connected backwards, the drive will not do anything.
You can try to flip the cable. Make sure you have the right cable too!
depending on which side of the cable the connectors are installed,
signals may end up on the wrong pins. You can check with an ohm-meter
between ground on the module and ground on the drive, you should have
continuity between the two (disconnect the power cables to make sure
the connection is not made there).
That's right it should be DH2 if memory serves me right but SCSI unit 0
Amigados expects the first SCSI unit to be called DH2 and this must
agree with the mountlist. Size can be calculated by multiplying
heads * sectors * cylinders = number of blocks
SCSI does not care about physical numbers so you can "make" a drive to
be 1 head 1 sector and 203,125 cylinders = RZ23 (104Mb).
as long as the numbers are pretty close, you should be OK.
When you prep the drive, make sure you use the manual mode, otherwise
the program uses funny values which may not agree with what you have.
Have "fun"

I seem to be set up ok . Double checked ,. But when prep is run on res2:
I see a quick flick of the led from the drive. I then enter in all the parameters
in manual mode and the drive led comes on and stays on. After this point i have
to reboot . To me it sounds like a bad controller.
Thanks for the reply Jean. I have been on holiday and offset.

| 4891.7 | RZ's are tough | SALEM::LEIMBERGER | | Fri Aug 16 1991 06:45 | 20 |
| I had the same problem when I put my RZ23 on the GVP SCSI bus. What I
ended up doing was I removed my 40meg, put the RZ on the card, and
formatted it with the floppy based software. Then I added the 40 meg
to the end of the bus. It works well now. If I had the RZ on the end
it would hang.
Now I am trying to get an RZ24 online to replace the RZ23. No fun!
I can use the same procedure above,and get it to format. But I can't
get the 40 meg to boot first regardless of what I do. If I boot off the
floppy I see all devices. If I do manage to boot the 40 meg I don't
see the RZ. IF the RZ boots I end up with a dead CLI. (nothing is there
of course). Now I think I could copy WB to the RZ24 and then boot and
see all devices but then I don't want that. I have also had the RZ
formatted,and tried to reformat in amigados, an got an "DH0 is write
protected" error message. The controller also seems to get confused
if I format, and go back to reprep. It tells me I am exceeding the
size of the drive. I have a call into GVP. RE -1 try my original
approach to see if it will work for your controller. strange beast
these RZ's. BTW anyone know how to hook up the led on the RZ24. It is
not the same as the RZ23. (light just stays on).
