This system lost access to its primary time reference. This might have been the result of a configuration change to the coordinated time network (CTN) ID for the CEC where this system was running.
The system enters a non-restartable wait state X'0A2' reason code X'15A'. If this system is not removed from the sysplex, the other systems might fail. If there are other active systems in the sysplex that did not lose their primary reference time, then XCF on those systems will detect a status update missing condition for this system. XCF on those active systems will partition this system from the sysplex according to the sysplex failure management policy if such a policy exists and is active.
Determine whether this change was intentional. Seek assistance from the system programmer.
If this message is not issued on every system in the sysplex, but issued on every system on the same CEC and the affected systems are all using STP for their time source in a coordinated time network, determine if the configuration change was intentional. If not, reset the CTNID for this CEC and re-IPL the z/OS® systems.
