How would I fix a back up error: 0510-089

I have been trying to do a backup from tape using the D ^DBREST command.  I am not able to connect to the tape drive, that recently got replaced.  It is configured and I can see it with IBM's ITDT.  I did a test and it came back with the error below:

Are there any suggestions on how to fix this or what commands to use to get this opened and connected?  I do appreciate it.
