Policy data is maintained on the CFRM couple data set, and therefore remains on the couple data set from one IPL to the next or from one use of the CFRM couple data set to the next. As part of its initialization, CFRM cleans up any status data in the CFRM couple data set that remains in what had previously been the active policy. The cleanup includes:

• Indicating that no system has access to any coupling facility.
• Setting the connections to coupling facility structures to a failed-persistent state (thus preventing connections from accessing those structures).
