Observe the following guidelines:
Logical hostname – A cluster name must be suitable as a hostname because Geographic Edition software creates the logical hostname by using the cluster name. Therefore, the cluster name must be in the naming system.
Unique cluster name – Cluster names must be unique. For example, if you have a cluster wholly within the domain .france, you can use hostnames like paris and grenoble. However, if you have a cross-domain cluster, you must specify the hostnames with enough qualification to identify the host on the network. For example:
You can link paris and munich with hostnames paris.france and munich.germany, and the cluster names remain paris and munich.
You cannot create a partnership between clusters paris.france and paris.texas because of a collision on the cluster name paris.
