I got the answer from Marion Hakanson (much appreciated!). Quite simple really, once you know the steps.
use rdtoc to get the file number of the image from each media it resides on.
use rdsplit to recover the image if it's multiple tapes. here's what I actually ran:
rdsplit 3 /dev/rmt/0n | rsh filer1 restore -xvfD /vol/vol0/home ./department/project
I guess this is why BT was so loved by those who used it. Very simple.

I have an old design tape that was made with Budtool's ndmp option that I need to recover. We no longer have budtool but one of the selling points of BT was that you could recover your data without it.
The tape was made by an ndmp dump direct to tape. Anyone know how to recover? I have attempted the following:
mt -f rst0a rewind mt -f nrst0a fsf 1 mt -f nrst0a fsr 2 recover TfD nrst0a /vol/recovery
Doing the above gets me a block issue: "block size should be 60 not 63". So I tried this (after positioning...):
recover TfDb nrst0a /vol/recovery 60
It vascillates between returning "Bad Header" and something about a 4k block.
