Thanks to Alan Rollow for his great answers. The first was to use MAKEDEV
instead of using mknod:
cd /dev
./MAKEDEV tz52 # (where tz(( bus# * 8) + target))
Then he also sent me the following procedure for testing inside of scu:

The sequence you probably want to go through at this
point is:
1. Unload the tape, if one is loaded.
2. Run scu.
2a. "show edt" and get the nexus (bus, target, lun) of
the drive.
2b. set nexus bus # target # lun #
2c. show device
This is the Inquiry data for the drive. Verify
that it looks reasonable.
2b. tur
This does a Test Unit Ready. It should fail,
there being no media in the drive, but it
helps verify communciation. The message should
hint that it needs media.
3. Verify that the tape you're about to load is the
right variety. DLT2000/TZ87 only uses DLTtape III.
Some versions of the TZ87 could read TK50 and TK70
but not most. Load the tape. When you get the "Tape
in Use" light and some density combination...
4. tur (no need to have left scu(8))
The command should quietly succeed. If not, then
it is either media or the drive. The message will
offer a clue.

Thanks again!
