Dear List,

the retention settings in the copygroup were to strict... The version
of the file we would like to restore has already been expired. :-(
However it is very likely the desired version of the file is still on
tape, as no reclamation has taken place. So my understanding would be:
if the file is still on tape, the "only" thing missing is the database
entry. Correct?

So the question would be: How to restore already expired objects from
a tape cartridge? Or: How to generate database entries for all
versions of all objects on a tape cartridge?

I guess the first step would be to move the respective node to a
copygroup, with "better" retention settings. I looked on the
documentation for "audit volume", but I did not get the feeling this
would understand checking "for inconsistencies between database
information and a storage pool volume" in un-expiring previously
expired objects...

Any tips, pointers, ideas?
Perhaps I am just searching for the wrong key words?

Gregor
