If you have drives that support Ks then you can mix Js and Ks. You
don't need to tell TSM. It will just use which ever the library mounts
in response to a scratch request.  If you want to control what data goes
on Js and which on Ks, then (unless you're running on zOS) you have to
predefine either the Js of the Ks (define volume) to a storage pool.
