hi Jay
Well, I am going to stick my neck out here, because reading the sysadmin
media manager guide, I dont think it can be done. I dont think the IMPORT
process is going to work on this either, as NBU will know about this tape,
and its current image contents.
The reason why I say this, is because the original data that was on this
tape has most likely been destroyed / overwritten with the new data now
stored on the same media.
Now, in case I am wrong, I will happily be shot down, but just in case, I
did find these link, which may or may not be much help.

Rule of thumb is, where at all possible, is to not manually expire tapes if
you can help it :-(
