A stop/start after MCL upgrade completed, fixed it, but why did it occur?
Cause
Following a name change event, the CPC that was in SERVICE status ended up going to OPERATIONAL. The REFRESH TOPOLOGY command was entered prior to the OPERATIONAL status appearing. The abend is caused because the server attempted to satisfy the DISPLAY TOPOLOGY command, but since the refresh had failed at this point, there was no TOPOLOGY.
Resolution
the OPSLOG it appears the CPC was not in a state that allowed the OPSBCPII server to respond to the REFRESH TOPOLOGY commands issued after the name change events. See below message explanation from IBM documentation Base Control Program Internal Interface (BCPii) Services:
101 HWI_COMMUNICATION_ERROR
Meaning: A communication error is detected. The hardware management console application API
(HWMCA) or the BCPii transport layer has returned with a failing return code.
Action: See the DiagArea for further diagnostic information. The Diag_CommErr indicates the
return code that is returned from HWMCA APIs or the BCPii transport layer.
HWMCA API and BCPii transport return codes are provided in Appendix A, “BCPii communication
error reason codes,” on page 637.
The server would have refreshed when the polling triggered here would have been able to determine the CPC's were available.
