I assume that you have followed http://support.microsoft.com/kb/244980 or
http://msdn2.microsoft.com/en-us/library/ms190460.aspx? Which version of SQL
Server is this?

When did you test the failover as it will take time to propogate the IP
address change. Have you tried to ping each of the servers or resolve the
names in the DNS?
