Thanks for all the answers. The new drive is being ordered.

The TLZ10 is the DDS-3 follow-on to the TLZ09, which was a
faster (than the TLZ07) DDS-2 drive built by Sony. It will
use the 125 meter tapes, where the TLZ07/TLZ09 would only
go to 120. It should read/write all the others going back
to the TLZ04. It is also faster than the TLZ09.
The built-in adapter on the 2100 family is basically a
KZPAA (both are based on the NCR 810 SCSI chip).
The Systems and Options catalog entry for the drive claims
it is supported by V3.2G. I check the device entry tables
on my V3.2G system and didn't see it, but I also didn't see
any of the other supported drives. It looks like you can
just plug it in and go.

Bill,
To a large extent, SCSI is SCSI, but with tape drives, things are often a
bit more complicated.
I assume you're running something in the V3.2x stream, since you comment
that an upgrade to the V4.0x stream isn't possible at this time.
The odds are that if there are any problems with the tape, they can be
addressed with edits to the SCSI CAM tape configuration files, but since
it's an older release, it's possible no one has developed the changes. On
the other hand, if it's V3.2G, it's possible the changes are already in a
patch kit that's available.
You really have to find someone who knows the support status for the drive
to give you a definitive answer. You *might* get lucky on the Digital
storage products web pages (through www.digital.com or even more likely
www.storage.digital.com).

You may want to try this, before swap the drive:
- Shutdown the system
- Power off the system
- Swap in the tape drive
- Power on the system, let it boot all the way...
- Rebuild the new kernel
- Then, reboot the system
You should see the new device after that...
