As usual the list comes through! I got two replies before I received
my message back from nwu.edu! I did not include all the repsonses,
just the ones that had something in them that the others didn't have.
The answer is to change the SCSI ID on SW2 on the MD21 adapter. The
replies follow my original message.
Many thanks for all the replies to:

A very special thank you to the person who faxed me 4 pages of
diagrams (you know who you are!). They were just what we needed.

} I couldn't have done it without a lot of hints and some pages from the Field
} Engineers Handbook. Good luck.
}
} Well, could you forward me a copy of the solution to this problem. It's
} something that I had been meaning to find out (but never actually needing to
} know). Thanks.
}
}
} Open the shoebox to be added. You'll find a controller board mounted
} in the middle, on a big U-shaped metal bracket, with four screws on the
} flange around the edge (a socket set with an extension is essential).
} Remove it; underneath is the SCSI/ESDI controller. At the front edge
} (away from the connectors end of the shoebox) is a DIP switch; just
} set it to the desired SCSI address (probably just move the first, or
} lowest-numbered, switch on, to get SCSI address 1). There's a yellow
} pack that looks like a chip; that's the termination resistor. Remove
} it (but SAVE it!). Put it all back together again. (;-)
}
} I never had success in adding any scsi-disk to an existing
} shoebox ( Sun3/60 or 3/1xx under SunOS 4.1.1 ). I tried Fujitsu, Maxtor,
} Micropolis and some other. I jumpered what ever was possible, but
} the Sun refused to add a second scsi-disk. I suppose it has
} to do with SunOS 4.1.1 .
}
}
}
} Is the Micropolis 1355 a SCSI disk or an ESDI disk? If the latter, the
} shoebox will have a SCSI "controller" (actually a SCSI-to-ESDI adaptor)
} with switches or jumpers to set the SCSI ID. For an Emulex MD21 board,
} these are switches 1-3 on switch block SW1.
}
}
} What you need to do is open the shoebox (take off the cover), then with the
} shoebox in front of you, facing the front of the box, look at the board on the
} bottom, in the middle of the box. This is the MD21 SCSI to ESDI controller.
} On the front right side of the board is a dipswitch. Move the first switch
} (closest to the front) to the ON position.
}
} That should do it.

} The second disk is also a 144 MB ESDI drive as shipped by Sun a few years back.
}
} The SCSI ID for the ESDI drives in the older shoeboxes is not located on the
} drive but on the ESDI/SCSI adapter (Emulex MD21) which is located under
} the tape unit. To change the SCSI address, you must change the jumpers/dip
} switches (I forget which) on the MD21 card. There is a row of 8 switches
} or jumpers on the card. The first (or last) three of these control the
} SCSI address on the adapter. Experiment a little.
}
} The problem you will run into is that both of the 1/4" tape drives are
} both set for SCSI address 4. You will need to change or disconnect one
} of these as well.
}
} Sorry I cannot provide more specific info, but my notes on this stuff
} are a few years old and burried and my memory seems a tad foggy on
} the subject.
}
} You might want to try to get newer equipment as soon as budget permits.
}
} Good Luck!
