Error description
For PowerHA customers at AIX levels 7.1.5 or 7.2.2 (RSCT 3.2.3.0), if there is a service IP alias on the same subnet as the boot address, and the adapter is declare down, while IP changes are being made to move the service address somewhere else, PowerHA will receive a report that the adapter is back up again, even if it is still down. The resulting false network_up event will not break the failover itself, but it will introduce a danger of future resource movements being handled inappropriately, if they occur while the adapter is still down and PowerHA is still being told it is up.
Local fix
Problem summary
At RSCT 3.2.3.0, a logic error in handling AHAFS events during PowerHA IP address handling, when a service and boot address are on the same subnet, could lead to Group Services erroneously reporting that an interface is UP again when it is still down.
Problem conclusion
The error in handling this specific sequence of events has been addressed.
