Generate CSR Certificate - Cluster instance

Hi,

 We are encrypting connections of our SQL Server and it is Active/Passive Cluster.

 I know how to generate CSR for getting SSL Certificate but I'm not sure about the FQDN to be used while generating CSR.

 Question: What is the FQDN name to be used while generating CSR file?

Thanks,
