Open a support call pronto. Tech support is excellent and they will be able to resolve this.
I had an issue where my autofailover was working fine, even when I shut the secondary off. But when the secondary came backup I lost my virtual IP. After a lot of work with the Open-E support folks and Todd Maxwell, they discovered that one of my bonded replication connections was flaky and causing the issue. Once I removed the flaky connection then everything started working great.
