Partition a 3494

[T.Y. Wu]

I need to add a 2nd RS/6000 TSM server to an existing 3494.  The book
says that IBM ATL must be partitioned for multiple TSM servers to use
the same library.  Exactly how is a 3494 partitioned?  What needs to be
done on the 3494 side?  I know I need to use different set of category
numbers for the 2nd server on the TSM side.
Thanks, T.Y.
