Problem:
I configured my 2 DSS systems with Auto Failover. Everything thing is working fine but the failback. As it never worked before. It only works when I deactivated the failover and perform the failback on a physical IP address not the used Virtual IP Address.
Solution:
If you have problems with the failback, please check that the replication ended and the connection is persistent.
Additionally make sure that the Virtual IP Address is configured on a separate subnet, than your bond. As it will cause a duplicated answers. Also, be sure that the target is not accessed from VMware (if used) and Windows simultaneously.
