Here is what we need to know to understand what you are doing:

1. Oracle version (3 decimal places)
2. Is failover being done with TAF or FCF
3. Is connection using VIPs (Virtual IP Addresses)

There is a sample TNSNAMES.ORA file for a RAC cluster in Morgan's Library at www.psoug.org under "REAL APPLICATION CLUSTERS." Look at how the host has been configured ... the host name does not even enter into the picture.
