When you create a cluster of hosts, some configuration warnings will be shown that they are related to host's dedicated resources. One of them you will face with network uplink redundancy. The best solution for this problem, is assigning more than one physical network adapter to the vSwitch that it provides the management functionalities (such as VMKernel) . But sometimes you have to ignore this warning, because probably you have only one physical adapter. for instance on lab or pilot environments, you can add this row to the Cluster advanced settings:
das.ignoreRedundantNetWarning (Value: True)
Also for some situations there is a warning that announcing "There is insufficient heartbeat datastore". If the management network is failed, HA will select two datastores for each host to check host's heartbeats for greater performance. It's suggested to select shared datastores. Therefore you need to go to the Cluster settings and into "datastore heartbeating" section, select more datastores. But if you don't have further than one datastore per your hosts, you can add this row to the "Cluster advanced settings":
das.ignoreInsufficientHbDatastore (Value: True)
