Explanation
This is the first message in a message group
that VTAM® issues when an attempt
to use a Peripheral Component Interconnect Express® (PCIe) service fails. VTAM uses PCIe services as part
of managing an IBM® 10GbE RoCE Express feature.
A complete
description of the message group follows:IST2391I service_name PCIE SERVICE FAILURE ON TRLE trlename
IST1684I RETURN CODE = return_code REASON CODE = reason_code
