Remove the “host currently has no management network redundancy” warning from your whitebox HA enabled ESX cluster
Fri-2009-10-16 8 Comments
When you completed building your ESX cluster from so called whitebox machines, you might see a warning sign at the cluster level. It will tell you the management network has no redundancy. This is probably correct because whitebox clusters usually don’t have 2 NIC’s for the management network.
To loose this irritating warning message do the following.
- Go to the properties of your cluster
- Select HA from the left pane
- Click the ‘Advanced Options’ button
- Fill in the first column of the first row by double clicking and typing the value ‘das.ignoreRedundantNetWarning’
- Fill in the second column of the same row by double clicking and typing the value ‘True’
- Close the Advanced Options window
- Now deselect the option ‘Enable HA’ and press OK
- HA will be disabled, this will take some time
- Go back to the options and select ‘Enable HA’ and press OK
- HA will be enabled and the warning will be gone

So this only removes the warning, but it does not actually solve the issue of having no management network redundancy?
Hence the title of the post “Remove the warning”. If you want to fix the issue, you need to add another NIC to the management vSwitch.
