You cannot dedup on DISK stgpools.
DISK implies random access disk - e.g., devclass DISK.
FILE implies serial access disk - e.g., devclass FILE.
But I think there is still an open question about collocation and
deduplication. Deduplication must be done using FILE stgpools, but FILE
stgpools CAN

This is my understanding as well. I'm almost certain this is the case, though
we have not yet used source dedup.

FILE.
But I think there is still an open question about collocation and
deduplication. Deduplication must be done using FILE stgpools, but FILE
stgpools CAN use collocation. I don't know what happens in this case.

Hello,
I had a student ask me today What happens if you have collocation turned on
for a storage pool that you are deduplicating? I did not know what to answer
because in my mind I thought well, if the data is collocated then I need to
have a copy of that data on that client's tape, otherwise
Tape pools are not de-duped, so that is not a consideration.

If it is a file device class with dedup turned off, yes.

Cool, Thanks :) I have questions about client dedup. Do you know of any
redbook detail on that?
Thanks,
