I'm sending this reply to -hackers because my original message went to
-hackers (rather than -hardware, as I had intended).  Apologies for the
confusion on my part; hope it's useful for someone.

Amazing...!  That's what it took:

> chio move slot 6 drive 0
> chio status
picker 0: 
slot 0: <ACCESS,FULL>
slot 1: <ACCESS,FULL>
slot 2: <ACCESS,FULL>
slot 3: <ACCESS,FULL>
slot 4: <ACCESS,FULL>
slot 5: <ACCESS,FULL>
slot 6: <ACCESS>
drive 0: <ACCESS,FULL>
> chio move drive 0 slot 6
chio: /dev/ch0: CHIOMOVE: Invalid argument
> mt -f /dev/rst2 offl
> chio move drive 0 slot 6
> chio status
picker 0: 
slot 0: <ACCESS,FULL>
slot 1: <ACCESS,FULL>
slot 2: <ACCESS,FULL>
slot 3: <ACCESS,FULL>
slot 4: <ACCESS,FULL>
slot 5: <ACCESS,FULL>
slot 6: <ACCESS,FULL>
drive 0: <ACCESS>


Somehow, on realizing this is what makes it work, I'm reminded of first
learning that the star-tipped rod scares the bird.... (*)

Thanks, Dan....

Now I need to get amanda set up to use this....  :-}
