I am fairly positive that with RSU=0, you can not dynamically move memory from one LPAR to the other one. Frankly, it's been so long since I messed with it I don't remember if you have to configure something on the hardware side (either HMC or HCD) to make this work or not. What I do remember is that the RSU value defines the amount of storage that z/OS (or os/390) sets aside in a relocatable fashion so that, if requested, z/OS can free up the requested pages to move them to a different LPAR. Having it set to 0, z/OS will not reserve any storage as removable so you cannot dynamically move any between LPARs.
I will defer to others on the list who do this more often than me to tell you what, from a hardware standpoint, you need to do to make some storage dynamically relocatable. I think it would depend on the hardware you're running as well.

RE: When Does the New LOCAL Get Used? RE: ILR006E COMMON PAGE DATA SET FULL,...) What kind of a box do you have? What level of z/OS? Then the big question - in SYS1.PARMLIB member IEASYSxx do you have anything defined in the RSU parameter? IIRC, if you either don't have an RSU parameter defined (which defaults to 0) or have it defined as RSU=0, then no, you can't dynamically move storage from one LPAR to the other. Check the Init and Tuning reference for IEASYS and RSU.

RE: When Does the New LOCAL Get Used? RE: ILR006E COMMON PAGE DATA SET FULL,...) First of all. Thank you all very much for the help with paging. Would anyone know if I can change the memory allocated to my 2 lpars dynamically (I want to take some from TEST and give it to PROD)? If I can can someone briefly tell me how? Thanks all.
