During the cluster creation process, you will be asked for a “Network Test IP Address.” Both servers will use this IP address to check if the network is still available. Both servers will regularly ping this IP address.
It is strongly recommended to enter multiple IP addresses there. These can be the IP addresses of your router, gateway, mail server, network printer, etc. By including multiple IP addresses, you enhance the reliability of network monitoring in the cluster, ensuring that the network is functioning properly.
