Description (partial)

Virtula IP's not removed on Primary Server after restart from Spilt-Brain Scenario

1. Perform HA b/w primary and secondary with both IPv4 and IPv6 Virtual IP with HA Automatic switchover.
2. both IPv4 and IPv6 virtual IP are sitting as below:
on eth0: IPv6 VIP is set
on eth0:0 , IPv4 VIP is set

3. Now perform split-brain, remove traffic between primary and secondary
4. primary remains in active mode and failover to secondary succeeds , both VIP's are set on secondary server.
5. Now re-establish network connection between primary and secondary,
6. primary server epnm restarts itself checking secondary as active as per process, primary moves 'Primary Synching'.

both IPv4 and IPv6 VIP's are not removed on primary server even after primary restart and 'primary synching' state.

Expected behaviour: 
Once primary restarts itself and moves to 'primary Syncing mode , both VIP's have to be removed. this works as expected when you perform normal failover..
