You have access to an account that is a member of the Local Administrators group, for example, egoadmin.
The required connection ports are not in use.
The default base connection port is 7869. EGO uses five consecutive ports from this base port (7869-7873).
If you customized the cluster name, cluster administrator, installation directory, or ports, you must use the same settings when adding another host to the cluster. Do not take the default settings when adding another host if you customized the installation on the master host.
Ensure the information you specify is free from typographical errors: the installation will not continue if there are errors within parameter entries.
Look for the host you added in the list of the resources.
If you can see the host name in the list of resources, that host was successfully added to the cluster.
This test detects hosts even if the host is not currently available. Some hosts make take a while to become available after they are added to the cluster.
