How to hide warnings when there is no HA management network redundancy.

When HA is enabled in a cluster, if there is no management network redundancy, the vSphere client shows an alarm icon on the host in the inventory, and displays a warning on the hosts summary page.  In this blog we look at how to prevent these from being displayed.

First of all let’s see the effect of turning on HA in our cluster, and with only one management network you can clearly see the warning message.

To disable this message from being displayed, edit the cluster settings, click on vSphere HA, then select the Advanced Settings button, click at the top to edit a row and enter the variable name das.ignoreRedundantNetWarning and enter the value true.  If you then turn off HA and back on again, the warnings will not display.

It should be noted that these warnings are there for a reason, it is best practice to have redundant management networks to ensure redundancy for heartbeat traffic.
