I believe you can "move data" data into the container pools, you just can't
get the data out with traditional methods at the moment but only via TSM
node replication.
I like the new pool type but they are only suitable to a specific type of
setup, the good news is that this setup covers a lot of the new type of TSM
deployments we are doing!
