You can write to 1 primary *and* upto 10 copy storage pools
concurrently.

I should clarify my answer.

There is no automated way to send initial backups to a primary storage
pool (DISKPOOL, for example) *and* multiple different copy storage
pools. You can modify a primary storage pool definition to concurrently
write to 1 primary and 1 copy storage pool concurrently:

  upd stg diskpool copystg=offsitetapepool

As to whether future release will allow automated writing to multiple
copy storage pools: probably not. Why? I have seen dozens of TSM
environment; not a single one of them used multiple copy storage pools
for the same data. (This is not to say they don't exist; I have just
have never seen one.) Why should Tivoli invest coding and debugging time
to such a feature when they have their plates full with more pressing
matters?
