title: Why can't I apply ToUpper() to an OwnerNode?
body: <p>This works:</p>
  
  <pre><code>Output "Cluster Group: ""$($Group.Name)"", Current Owner: $($Group.OwnerNode), Current State: $($Group.State)"
  </code></pre>
  
  <p>This does not work:</p>
  
  <pre><code>Output "Cluster Group: ""$($Group.Name)"", Current Owner: $($Group.OwnerNode.ToUpper()), Current State: $($Group.State)"
  </code></pre>
  
  <p>With an error of this:</p>
  
  <pre><code>Method invocation failed because [Microsoft.FailoverClusters.PowerShell.ClusterNode] doesn't contain a method named 'ToUpper'.
  </code></pre>
  
  <p>Any ideas on how to get this to string from the output of the Get-ClusterGroup string to upper case?</p>
