Drive failed in library. Jobs queued

Hello,

 I had a tape drive fail in my robotic library.  There are (were) two drives.  I am getting a replacement, but in the meanwhile, BE will not backup.

All drives stay at queued, and inventory fails showing "Incorrect function" on 24 of the 48 slots.

What I've done:

  Attempted to delete any occurrence of the failed device. 

  In addition to reboots, etc.

I'm not sure what else to try at this point.  I do not have any bad or missing devices.
