The Sysplex Failure Management policy specifies that system sysname should be removed from the sysplex when system sysname has not updated its system status for as long as its failure detection interval. However, system sysname has produced signal traffic within its failure detection interval. The system is functional but cannot write its system status. This may be a temporary event or system sysname is not functioning properly. XCF message IXC427A provides more information.
Processing continues. System sysname will be automatically removed from the sysplex if it does not update its status and it does not produce XCF signal traffic within its failure detection interval. If the operator replies SYSNAME=sysname, then XCF starts the removal of system sysname from the sysplex.
If system sysname is functional, then do nothing. If system sysname is not performing properly and its removal is deemed necessary, then REPLY SYSNAME=sysname to have XCF isolate and remove system sysname from the sysplex. If the reply is incorrect, the system issues message IXC208I to notify the operator of the error, Then, the system issued IXC426D again.
Frequent occurrences of IXC426D might indicate contention or poor performance of the sysplex couple data sets. You need to investigate the performance problem.
