Actually, on my tape pools I had to enable collocate by group instead of node. 

I don't see the point in doing a move nodedata. Why would I want to collocate 
all my data on that node ? If I run a selective on all filesystems, I would 
have a full image of what the syestem looked like today. If I had a DR 
situation in a week , then 
I know that most of my data is mostly on one tape. If I do a move nodedata and 
move all the data, I would have a lot more tapes to deal with. I would rather 
let retnetion/expiration come into play and drop the older files and keep my 
collocation "clean".

I'm going through a similar process right now. I think you want a MOVE
NODEDATA command to move the second node's data into the collocated
storage pool.

As it is, when the client runs what you call a "full incremental," the
client sees that most of the data is already on the TSM server -- and it
doesn't care that it's not in the storage pool you want it in. (Why
should a client care about storage pools, right?).

Hope this helps,
