VMware vSphere Host currently has no management network redundancy.

Resolution

This message appears if the Service Console does not have network redundancy configured properly and can be safely ignored.

To prevent this message from appearing and to comply with proper network redundancy, VMware recommends that you add a second service console on a different vSwitch and subnet. Alternatively, you can add a second vmnic to the service console vSwitch.

To suppress this message on ESX hosts in the VMware High Availability (HA) cluster or if the warning appears for a host already configured in a cluster, set the VMware HA advanced option das.ignoreRedundantNetWarning to true and reconfigure VMware HA on that host. This advanced option is available in VMware Virtual Center 2.5 Update 3 and later.

Note: If the warning continues to appear, disable and re-enable VMware High Availability in the cluster.

To set das.ignoreRedundantNetWarning to true:

1. From VMware Infrastructure Client, right-click on the cluster and click Edit Settings.
2. Select VMware HA and click Advanced Options.
3. In the Options column, enter das.ignoreRedundantNetWarning.
4. In the Value column, enter true.
   
   Note: Steps 3 and 4 create a new option.
   
   
5. Click OK.
