If "mt" says there is no tape, there isn't any tape.
Amanda has nothing to do with it.

I see that the drive is an OnStream. Haven't there been
significant problems reported on this list, with those?
For remote backups I prefer to keep a local mirror, using
ssh and rsync, and back up from that. When tape drive
problems develop, and they usually do sooner or later,
I'm not depending on all too often ill-trained and overworked
ISP sysadmins to do my troubleshooting for me.
Instead, I do the troubleshooting with my own ill-trained
and overworked self (chortle) !!!
Another option might be changing colocation providers.
