Indeed, the file is saved at /nsr/res/dbg. The file is an ascii-file. Within there is a value for an Resource identifier, refer to a Tapelibrary. Selecting the noted Library in nsradmin, the identifier are different ?. But the Library works. What does that mean?

Do cat /nsr/res/nsrdb/03/002b02290000000000000000458150df0a84801a and see what it is. Chances are something was fauly and is no longer there, but rather under /nsr/res/nsrdb/dbg instead. If so simply check what resource was it and if you see if from GUI. If not, simply recreate it.

I"m not sure what resource that was, but something was wrong with it and upon check NW removed that from active config to dbg directory where faulty things are kept. At that point two things may happen:
- new resource will be created if required
- resource needs to be created manually

If everything works fine chances are that you don't need to worry.
