IST2390I

Explanation
This is the first message in a message group
that VTAM® issues when an attempt
to register a Peripheral Component Interconnect Express® (PCIe) device fails. VTAM uses PCIe services as part
of managing an IBM® 10GbE RoCE Express interface, and part
of that management is registering the underlying devices before activating
a 10GbE RoCE Express interface.
A
complete description of the message group follows:IST2390I IQP1REG PCIE SERVICE FAILURE
