First, thanks to everybody who responded to my request for help with the
exabyte drive.
Now, here's how I have everything installed.
1) Install the s/w patch tape that comes with the tape drive as per the
instructions provided.
2) Shutdown the system
3) Install the internal to external SCSI connector.
- remove the card cage plate from the internal to external SCSI
adaptor (the adaptor comes attatched to a back plate that could be
screwed into the system cabinet card cage.
- remove the top and left (as you face the unit) panels from the
system cabinet
- remove the SCSI terminators on the 1/4" 60Mb cartridge tape

- The figure above is a side view of the 3/260 system cabinet. The
'='s show the location of the SCSI terminators (note the 1/4 tape
drive is iin front of the controller card.)
- Run the head of the internal-external SCSI bus through the slot
in the top of the system cabinet. Connect the head (making sure that
pin 1 matches pin 1 (the red stripes on the ribbon cable)).
- Make sure the ribbon cable is laying flat across the top of the system
cabinet. Replace the side and top panels being sure not to fasten the
top panel screws too tight.
- Place the SCSI adaptor on top of the system cabinet so it does not
block the fans.
4) Change the exabyte device address to st1.
- remove the exabyte cover.
- set DIP switches 1 and 3 to ON
5) Make sure all connections are correct.
6) Power up the Exabyte, waiting for both the red and green led's to light up.
7) Boot the Sun. Once the Sun boots the exabyte LED's should both be off
(unless you have a tape loaded, in which case the green LED is on).
8) Be sure that st1 shows up in the boot messages. If not add it to your kernel
and rebuild.
9) Make sure the /dev/rst1 and /dev/nrst1 exist. If not then:
cd /dev
MAKEDEV st1
10) test the drive.

Important information about booting a system with Exabytes...
I learned this from a knowledgable technician, after months of wierd
problems and of support calls. It ain't in the manual and may apply to
BSD UNIX systems with autoconfigure code only, not sure...
1. When booting your system, you must(!!) have a tape in the Exabyte unit.
A tape must be in the unit to pass the self test!!!!
2. After power up, the controller gets tickled and goes through a
self test procedure which takes 1-2 minutes! I shall repeat --
a tape must be in the Exabyte unit to pass the self test!
The Exabyte drive lights should go from
Off
Yellow+Green
Off
Green Only
3. It is only at the "Green Only" state that you can load UNIX
and have it do its auto-configure thing!
Failure to wait for the Green-Only light leads to chaos.
Our procedure on a MicroVax is to leave the auto-boot switch to manual:
1. Power on.
2. Inital boot load, and get the prompt:
>>>
3. Wait a couple minutes while the Exabytes thinks.
4. When the Green light only comes on, boot UNIX.
It's been working like a charm ever since!

Summus ships an enhanced version of the same controller/driver with its 2.3GB product (that is, the "Gigatape" :-) ) so the installation procedure should be the same if TTI hasn't modified it. We do not recommend that you remove the original SCSI board (I'm not even sure if the system could boot off the other SCSI). There is no reason they cannot both exist in the same system. Try rebooting, but this time put the original SCSI board back in its slot, and the new one in any available slot. Be sure to remove the backplane jumpers (BUS GRANT 3 and IACK) for that slot. It should atleast boot properly now. If the system doesn't detect the controller double check your config file. It should include something like: controller rfsdc0 at vme16d32 ? csr 0x???? priority vector rfsdintr 0xF8 tape rfsd0 at rfsdc0 drive 40 flags 0x211 (the csr shouxld be a valid vme address not in use, and set properly on the SCSI board) This is assuming they left the naming conventions intact, that the Exabyte is the only device on the bus, and that the Exabyte target id is set to 5. You will have to consult your installation guide for other configurations. I hope that wasn't too confusing. In short, don't replace the original SCSI!
