I read it to mean that when at least 10% of the data on the volume is
reclaimable, reclaim the volume.

In your scenario, though, the 90% wouldn't necessarily be empty it would just
be filled with dead data - data that has been removed from the database
because it has been deleted or aged past the time it was to be kept.

My understanding of the purpose of reclamation (and believe me, IBM's way of
looking at these percentage things is about as confusing as I can imagine)
was to delete the actual data of the files that had already been removed from
the database for whatever reason.

Feel free to correct me if I'm wrong.  The one thing I know for sure is that
when we drop the reclamation threshold to 10%, reclamation processes start up
almost immediately.

Luanne - I hope I'm not giving you false information.  My bet would be with
Kelly, though,  since he's waaaaaaaaaay more experienced in and knowledgable
about  the workings of ADSM than I am.

Subject: Re: reclamation

I thought the reclamation percentage meant the amount of useful data left on
the tape.  So 10% means there is only 10% of the tape that has valid data,
or in other words, 90% of the tape is empty.
