adding cluster resource to sql server

$res = Get-ClusterResource -Name 'New IP Address' | Get-ClusterParameter
$parameter1 = New-Object Microsoft.FailoverClusters.PowerShell.ClusterParameter $res,Address,192.168.11.10
$parameter2 = New-Object Microsoft.FailoverClusters.PowerShell.ClusterParameter $res,SubnetMask,255.255.255.0
$parameterList = $parameter1,$parameter2
      $parameterList
$parameterList | Set-ClusterParameter

Then i get the following

Object                                  Name                                    Value                                  Type                                  
------                                  ----                                    -----                                  ----                                  
New IP Address                          Address                                 192.168.10.10                          String                                
New IP Address                          SubnetMask                              255.255.255.0                          String                                
Set-ClusterParameter : Unable to save property changes for 'New IP Address'.
At line:8 char:18
+ $parameterList | Set-ClusterParameter
+                  ~~~~~~~~~~~~~~~~~~~~
    + CategoryInfo          : NotSpecified: (:) [Set-ClusterParameter], ApplicationException
    + FullyQualifiedErrorId : System.ApplicationException,Microsoft.FailoverClusters.PowerShell.SetClusterParameterCommand

so this works

$res = Get-ClusterResource –Name "New IP Address (1)"
     
$param1 = New-Object Microsoft.FailoverClusters.PowerShell.ClusterParameter $res,network,'Cluster Network 1'
   
$param2 = New-Object Microsoft.FailoverClusters.PowerShell.ClusterParameter $res,Address,192.168.0.92
     
$params = $param1,$param2

$params
     
$params | Set-ClusterParameter

I am unable to set dhcp on this cluster resource - it is greyed out.

Any ideas why?
