Coupling facilities configured to use storage-class memory (SCM) provide storage extensions for coupling facility list structures. SCM provides relief for temporary CF real storage capacity constraints and additional structure capacity when needed during peak processing periods.

When the check is run in verbose mode, all coupling facilities connected to by the local system and in the active CFRM policy that have storage class memory available to be used as structure storage extensions will be listed along with the allocated structures in the coupling facility eligible to use SCM.
