You could look at the last written date, any tape written to since the last 
backup "backup stgpool" was completed 
Should be needed.

Subject: Tapes required by backup stgpool

Hi everybody,

TSM 6.2 on AIX 5.3

Is there any way to determine the primary tapes needed by a "backup stgpool" 
command before launching it.

Thanks in advance.

Regards.
