Thank you to those that wrote back yesterday, especially Don. I used the non-compressed device (in this case, /dev/rmt/1n), and amanda did indeed write filesystems until it hit EOT and rewrote that specific interrupted filesystem to the next tape.
Does anyone here have a changer working with more than one drive? The 30-slot StorEdge changer I'm working with has two drives installed, and I'm wondering how I can best utilize both of them. - Eric
