Hi,
That is probably because you only have 2 or 3 partitions on your server you try

Grigori,
The primary decision for limiting deduplication to device classes of
DEVTYPE=FILE has to do with the deduplication processing itself. Once a
data chunk has been identified as being a duplicate of an existing data
chunk, the TSM server leverages the reclamation and aggregate
Try a storage pool of the device class FILE, not DISK. It is FILE that
is supported for deduplication, although I haven't had a chance to use
deduplication yet, and my experience with FILE is fairly limited.

Grigori,
TSM can only dedup on devicetype FILE. As to why? Well, because new
features are only implemented on devicetype FILE. That was a desicion
made a few years back. Eventually, with TSM server version 7 or 8 or
maybe when we're all long gone deviceclass DISK will be removed
