Are you sure you have the same amount of memory as you had prior to the upgrade available the LPAR? (don't laugh, I've seen problems like this) To start you might want to go back to some SMF data prior to z/OS 1.11 and compare the working set sizes of all your address spaces (type 30s) to see what might have changed. SORT REAL D in an SDSF DA and and RMF III STORF might also provide clues assuming you have an idea of what things looked like before z/OS 1.11. BTW, what release did you migrate from?

I work with the OP. We are migrating from z/OS 1.9 and it is indeed a z9, so HSA is still part of the customer's central storage. We have found an OPEN APAR OA33307 which describes our problem.
