[comp.sys.amiga.tech] A3000 scsi bus screwiness...

I'm not sure where this should go, but here goes...

I've got an A3000/25-50 that I'm trying to add a second SCSI drive to.
Every configuration I've tried has shown similar problems - the boot
drive isn't seen every other boot. Best behavior is that after
powering the system on, things boot normally, then every other soft
reboot I get the animated "Workbench" requester.

The second drive is a DEC RZ23, which is a Conners CP3100 in DEC
clothing. It's also the boot disk. It works just fine if the Quantum
LPS50 isn't in the system.

The following configurations have been tried:

RZ23 external, both drives terminated.
A3000 -> LPS50 -> RZ23, only the RZ23 terminated (the "correct" configuration?)
A3000 -> LPS50 -> RZ23, both drives terminated
LPS50 -> A3000 -> RZ23, both drives terminated.

If the problem only showed up at power-on, I'd believe it were spin-up
time on the RZ23. But it occurs after soft reboots, also. What's wierd
is that the power-on boot loads Kickstart, _then_ displays the
animated workbench prompt!

So, any SCSI wizards out there got a suggestion? Need more information?
