Debbie:

I not clear on why 5% temp storage would seem to be unusual. Without knowing 
how "big" your system is and how it's used, there's no way to really guess; but 
5% is a reasonable amount.

With nothing else to go on, I'd say you're in great shape.

One minor note... A good part of "temporary storage" can be reclaimed without 
an IPL. Simply ending and restarting your various subsystems will handle a lot 
of it. That directly implies that the jobs in those subsystems are also ended. 
As days go by, system server jobs, subsystem monitors, etc., have joblogs and 
other elements take little bits of storage temporarily. When the jobs are 
ended, some of the stuff in temporary storage gets moved into permanent 
storage, e.g., spooled joblogs, and other stuff is simply deleted.
