Coupling Facility System Paths Warning

 

Suggested Actions

Coupling facility path contention is high, or a link is down. Performance degradation may continue until action is taken to reduce the traffic or increase the data bandwidth to the coupling facility. Traffic may be reduced by adding coupling facilities; bandwidth may be increased by using more links or faster links. See the IBM Redbook OS/390 Parallel Sysplex Configuration Volume 2: Cookbook, Publication number SG24-5638 for details and further recommendations.
