I am pretty sure that you have to restore the files first from backup,
and it is a manual process. Least it was for me when a HSM tape went bad
in the past. Had to use TSM to generate a list of the files on the HSM
tape, and then feed that in to a dsmc restore, before doing a reconcile
and removing the tape from the library for destruction.

Finally all the files where punted back to tape.
