The system administrator might need to redefine the CFRM policy to remove the current coupling facility from the preference list in the CFRM policy and make sure that the preference list contains another coupling facility that has both enough space for the new structure and connectivity to all systems currently connected to the structure. Once the CFRM policy is defined, the system administrator activates the new CFRM policy and issues the SETXCF command to start rebuild processing.
