Setting the SeparateMonitor Property

Hi

I am trying to set the SeparateMonitor value for a cluster resource but my code seems to not be working. I have tried the following

Get-ClusterResource CAUHyper2dt | Set-ClusterParameter SeparateMonitor:$False

Get-ClusterResource | Where-Object {$_.name -eq "CAUHyper2dt"} | % {$_.SeparateMonitor='False'}

but neither of them work, I am sure my code is just a little wrong, but I cant think how to correct it. can someone help me please?

thanks

Steve
