Bumped in to this a billion times by now, and I wouldn’t recommend applying this in production but for your lab when you need to take clean screenshots it works great. I’ve mentioned this setting before but as it was part of a larger article it doesn’t stand out when searching so I figured I would dedicate a short and simple article to it. Here is what you will need to do if you see the following message in the vSphere Web Client: this host currently has no network management redundancy.
- Go to your Cluster object
- Go to Settings
- Go to “vSphere HA”
- Click “Edit”
- Add an advanced setting called “das.ignoreRedundantNetWarning”
- Set the advanced setting to “true”
- On each host right click and select “reconfigure for vSphere HA”
This is what it should look like in the UI:
You can also do this in PowerCLI by the way, note that “Stretched-Bluefin-Frimley” is the name of my cluster.
New-AdvancedSetting -Entity Stretched-Bluefin-Frimley -type ClusterHA -Name "das.ignoreRedundantNetWarning" -Value "true" -force
Hi Duncan, this would mean you bypass the warning sent by HA? this warning can be ignored?
Duncan Epping says
Well if you don’t care about the redundancy yes you can ignore this, but typically you will want to have it resilient.
