You're missing an important part: the LPAR definition in the HMC must allow for reconfigurable storage as 'RESERVED'. Moreover, you can move only the chunk you define there. In particular, you can't define more than one chunk, and you can't move just a portion of the chunk. It's all or nothing.
Good news is that this does not require a POR, but you do have to bounce (ACTIVATE) each LPAR involved, both donor(s) and recipient(s), but not all at the same time. Since the OS capability derives from the hardware definition, by far the best way to set the parm is IEASYSxx is this: RSU=OFFLINE This tells RSM to mark a reconfigurable area of storage that is equal to the LPAR's RESERVED amount. This area is treated specially in terms of page fixing in order to allow it to go offline on demand. Be sure to include a command at IPL (in COMMNDxx for example) to put the RESERVED storage online to whichever LPAR should normally own it. To move storage around, issued these commands: On the donor system: CF STOR(E=1),OFF This may take a while to complete depending on relative size and how busy the system is. After this completes: On the recipient system: CF STOR(E=1),ON Assuming there is available storage, the effect is immediate. We use RSU to provide storage for DR images so that they don't tie up any resources unless we IPL them. We don't use RSU for day to day operational adjustments. . . .
