Coupling facility LP storage planning considerations

You must define at least 1024 MB of central storage for a coupling facility LP to activate.

This storage is reserved for coupling facility control code use and cannot be used for other purposes. Minimum storage size for coupling facilities is primarily a function of the coupling facility control code level. This implies that, over time, the minimum storage size required by a coupling facility on a particular machine can grow as new coupling facility control code updates are applied.

You must also define additional storage to accommodate the shared structures and dump space used by software subsystems using the coupling facility.
