Hi!
If I understand you correct,
you are adding second Magstar DRIVE , not
a second library.
If so, you do NOT have to create 2nd tapepool.
You can just add this magstar as a second drive
to you TSM-defined library (Query LIBR)
The limitation you speak does not apply 
to manual libraries (simple drives in *SM jargon)
