Well thanks Eugene.

Typically, this documentation first recommends that only a single
container be declared for a ts on a raid device. Seems to anyway.

It then proceeds to a lenghty discussion of tablespaces with more than
one container defined....presumably still on a raid device as that is
the module heading.

We are constrained in our configuration settings as we are tied in with
Siebel, until Oracle drops support for DB2 anyway. That's why the
question. This documentation doesn't really answer the question so I've
opned an ETR with IBM and will see what they have to say.
