Hi,

 

We run network failover on the self ip in several HA deployment on vCMP enabled guests and it works fine without any issues.

 

I think that you should test a failover without configuring the unicast mgmt addr and see the results.

Though it's written in the documentation, there is several scenario you can't apply this. For example when running vcmp guests in strict isolation mode. Having the mgmt interfaces in the failover config is a fallback to the self ip communication. Because the heartbeat can fail on the self ip network, having a different secondary network, the network failover is more reliable
