Delete the DLT drive, add it manually with tpconfig on the media server 
that contains it, try to use it, see if it has any problems, if it works, 
you're all set-- then open a ticket with Symantec to find out why the 
auto-detect is failing.

If it does not work manually, then there is another problem.
