Hi David,

If you turn off deduplication, the dedup informations are kept. In order to "rebuild" the "full" data, you'll need to move them to another storage pool where deduplication is also turned to off.

That's one of the reasons why it's advised to test with a new copy storage pool wich can be easily destroyed.

What happens when I update a stgpool that has DEDUP=YES back to
DEDUP=NO? Does the dedup data stay deduped and the new data is stored in
full? Or does TSM invoke a reconstitute process to inflate the data back
to its original form
