Actually they changed but in a manner I expected. When I disconnected
drives 0 and 1, leaving drive 3 on, I turned off nst1 and 2. Linux
automatically put drive 3 at nst0, etc.
I changed all the cables yet again and now it seems to be magically
working. I'm beginning to hate this thing. Anyone got an 8mm library
for sale cheap? :>

> My suggestion to solve your problem would be:

> 2. Use inquire to check that you see all tapes and the auto-changer.
> 3. Open the changer door and insert a tape into the first drive.
> 4. Use the "mt" command to rewind the tape.
> 5. Use tar to write and read back from the tape.
> 6. Note the device name you had to use for this drive.
> 7. Eject the tape from the drive
> 8. Repeat steps 3-7 for your additional drives.
> 9. Run jbconfig and now use the device names as found earlier in the
