After a very bad manipulation several nodes as well as their associated
filespaces was destroyed.
I make a migration forced with my diskpools on my tapepools every evening
I make a backup of my diskpools on one short_tapepool every evening
I make a copy of my tapepool on one long_tape pool every evening
I make a backup of the base TSM every evening.

Exist it a solution so that I recupere nodes detruits associated with
filespaces
