I currently have a mod 3 and a mod 9 Page Pack at L1.
Brian suggests using this maintenance upgrade as an opportunity to
eliminate the mixed PAGE Packs at L1.
My Storage Group is balking at the idea of giving me another mod 9 for
paging.
Will I impact performance if I replace my 2nd mod 9 Page pack at L1 with a
mod 3, to match the other mod 3 page pack?
Here is some L1 steady state data:

Re: Multi Page/Spool Directory Defs
As others have mentioned, they are placeholders to prevent directory
managment software from allocating minidisks on them.
What I also noticed was that your PAGE space is a mix of DASD sizes.
Check out the recent thread discussing the pitfalls of doing so. You
might want to fix that on your 1st level system.
