OK, I've got my tape drive working (thanks Ana!) but I'm having trouble 
connecting to the autochanger it's in using the director.  This is the first 
time I've tried having a storage daemon on a different machine than the 
director.  The director is a slightly lower version (7.4.3 on Debian Jessie 
using backports) than the storage daemon (7.4.4 on stretch) but I had 
understood that those versions were close enough to work.

So I'm hoping this is another configuration issue.

Right now what I'm trying to do is label all the tapes in the new library.

When I try to access the new storage from the director, it is able to get a 
listing of all the tapes, but it fails when it tries to actually do the 
labeling.  I get a "3999 Device not found or could not be opened" error.  These 
errors show up quickly, there is no delay as it tries each slot, so it's 
obviously not getting far enough to try.  But it *is* obviously connecting to 
the remote storage, otherwise it wouldn't be able to obtain the slot list.

What am I missing?
