Error description
It can happen that CAA is asked to add an existing cluster node to a cluster as a completely new node. This leads to the cluster temporary inconsistency as repository uuids are duplicated. The inconsistent state is resolved next by stopping the duplicated cluster node followed by an AIX reboot. This kind of problem can occur when a hostname change has been implemented and managed by PowerHA 7.1.3, e.g. - When an application server does a temporary hostname change and the change is propagated to the CAA cluster because the CAA cluster is configured to track hostname changes. Propagating a hostname change to the CAA cluster can be enforced by running the following PowerHA command: # clmgr modify cluster TEMP_HOSTNAME=allow
Local fix
There is no workaround to the problem.
Problem summary
If an existing node (but hostname specified in a different manner) is requested to be added to a cluster, it is possible for the ADD_NODE to succeed but the JOIN_NODE to fail.
Problem conclusion
Add a check such that the ADD_NODE will fail if the target node is already in the cluster.
Temporary fix
