If Dmgr and nodes are running on version 126.96.36.199 or higher, then adding new member into cluster will fail during the WPSconfig cluster-setup task due to WAS version 188.8.131.52 introduced changes to the scoping behavior of the application server. Portal scripts previously looked at the server scope for certain resources. This results in failures during WPSconfig cluster-setup for both the primary and the secondary node.
This issue was resolved by following steps:
1. Downgrading WAS version onto Dmgr and all nodes by uninstall WAS fixpack which was installed after fresh installation.
2. Install the portal fix PK38907 and PK68347 onto the new member.
3. Run WPSconfig cluster-setup task.
