The storage for a coupling facility LPAR is defined in the same way as a non-coupling facility partition. However, the storage in a coupling facility LPAR cannot be dynamically reconfigured. If another partition on the same processor fails, its storage cannot be taken over by the coupling facility partition. Or, if the coupling facility partition fails, its storage cannot be taken over by another partition.

You can also configure storage-class memory to a coupling facility LPAR. As with coupling facility real storage, you cannot dynamically reconfigure storage-class memory.

The DISPLAY CF command displays information about coupling facility storage and storage-class memory , including the total amount, total in-use, and total free storage. The RMF™ Coupling Facility Usage Summary Report provides a more permanent copy of this information.
