If you're getting them on all 4 chpids, then there must be something common to all 4 chpids that is causing the problem: - Are all 4 chpids plugged into the same card on System z? - Is your director/switch logging any errors? - Did someone yank on a group of cables, damaging them or stressing the connectors? Back in the day, an IFCC on a copper channel was usually the result of a bent pin or poorly seated connector. That is, electrical signals were not flowing properly. If the light isn't shining properly, you can get an IFCC on an optical cable. The h/w guys will have to help you with that. Alan Altmark z/VM Development IBM Endicott
