I’m in the middle of configuring the latest incarnation of my home virtualisation lab. It’s based on VMware 5.1 with vCenter and is configured using a similar architecture to many small corporate or SMB production systems. I have multiple hosts, configured as a small 3 host HA cluster and I’ve encountered the dreaded ‘ Host <xxx> currently has no management network redundancy. ‘ My OCD wont allow me to ignore it, specifically as I’m constantly reminded of it on the summary screen and treeview

It’s a known issue - you have a couple of options; if like me you are using distributed switches and have the virtual adapter bound to multiple uplinks you can safely disable the notification. VMware have a knowledge-base article,
Network redundancy message when configuring VMware High Availability in vCenter Server (1004700)
or you can skip and find the solution below :-
To set das.ignoreRedundantNetWarning to true:
- From the VMware Infrastructure Client, right-click on the cluster and click Edit Settings.
- Select vSphere HA and click Advanced Options.
- In the Options column, enter
das.ignoreRedundantNetWarning - In the Value column, enter
true.Note: Steps 3 and 4 create a new option. - Click OK.
- Right-click the host and click Reconfigure for vSphere HA. This reconfigures HA.
