Windows Server 2016 Cluster Nodes are missing the site attribute

Hi,

I have a Windows Server 2016 cluster in which the cluster nodes are missing the "site" attribute. I know that this is a new 2016 feature and that my cluster is a upgrade from 2012-R2 but the cluster functional level was raised to 9 (2016). What else should I do to be able to use the site awareness feature?

When I try to set site awareness, I get:

PS C:\>  (Get-ClusterNode MyClusterNode1).site=1
The property 'site' cannot be found on this object. Verify that the property exists and can be set.

When I try to see the properties of a clusternode, I get no "site":

PS C:\> Get-ClusterNode | Get-Member s*

Name              MemberType Definition

SerialNumber      Property   string SerialNumber {get;}
State             Property   Microsoft.FailoverClusters.PowerShell.ClusterNodeState State {get;}
StatusInformation Property   Microsoft.FailoverClusters.PowerShell.ClusterNodeStatusInformation StatusInformation {g...

Thanks.

Thomas.
