With the release of VCSA 6.5 an exciting new feature of vCenter HA has been introduced. So while doing the Basic HA configuration I was continuously getting below error in the wizard –
The operation is not allowed in the current state. Failed to get management network information. Verify if management interface (NIC0) is configured correctly and is reachable.
When preparing VCHA manually this error is more meaningful -
Exception: Unable to get hostname resolved IP address for eth0
It was due to my vCenter DNS record was missing PTR record and prepare VCHA stopped reporting error after creating it.
