How to replace a faulty node in HAA.
If the cluster has a faulty node that you would like to replace, all you need to do is add a new node to the cluster. The cluster recognizes the existence of a faulty node and automatically replaces it with the new node.
Create a new VM with the same OS as the decommissioned one then download the same version of HAA on it and install using either get-haa.sh script with the correct details (same username and password for HAA cluster and join it to one of the available nodes from cluster) or using install-haa.sh script.
After the installation succeeded in a web browser access the Web Management console of the newly installed HAA node https://IP_ADDRESS:8443 and click on “Setup” button.
In the node configuration page complete the details as follows:
In the Cluster configuration section select “Join cluster”, complete with the IP address of a node in the cluster (a healthy node), email and password to access the cluster and hit Next button.
A message will pop-up in order to confirm the procedure of replacing the faulty node.
