Question 9-track dinosaur

We just went from HP-UX 10.20 to 11.00.
All the bugs are out, except for a small detail...the old 9-track isn't working.
We receive large amounts of data on reel-to-reel so I kinda need it fixed. In the meantime, I'm trying to see if they can send me a DAT tape instead.
I'm pretty sure the drive uses 1600 compression. So I created a custom device file for it, but to no avail. The error I get is, Check Ring, Privileges etc.
The user is root, so I can't see it being privileges. Argh.
The old device file was called /dev/rmt/1600m. I can't seem to duplicate that file. I tried everything I can think of.
Does anyone know of any tricks to share?

Run "ioscan -fnC tape" and post the results.

The device shows up, but for some reason, it's unreadable.

I don't have an 11.0 system with a tape2 driver but the man page implies that this should work. How were the 1600 special files created? What does
lsdev /dev/rmt/c1t4d0D1600
lsdev /dev/rmt/c1t4d0wD1600b

I tried creating the special device files for D1600 compression, but those don't seem to work.
I really don't know how the previous dev file was created because it was just "always there". It was lost when I re-loaded unix 11.0.
The program that needs to access it has an entry for the device file I can change, and also has this entry:
Device_6=48~48~MT~M/UX~~("avl":0:2048)~~9 track 6250
I don't know if this needs to be changed.

I really need to see what you get from the commands
lsdev /dev/rmt/c1t4d0D1600
lsdev /dev/rmt/c1t4d0wD1600b
