Given a computer name, how to test it if it a cluster node or not? without 
calling WMI MSCluster with $null return? Are there any classes with a 
property of IsClustered?

Thanks,

Ben

Only WMI classes i can find that relate to clustering are listed here -

but I think you are aware of these.  Is there a Registry key that defines a 
server as a cluster member?

Hi Ben,

to achieve what you want, I was using WMI. Do you have any problem with that 
approach?

Check if Cluster Service is installed, and if it's running. That might give 
you some indications if it's a cluster node.

But WMI classes would be your most reliable answer, imho.

Hi, RichS, Jason and Martin,

I am able to use WMI classes. It works great for a cluster node. But if it 
is a non-cluster node, the testing takes a long time and errors out with 
return value $null. How to work around this?

Hi Ben,

you will need to test this, however this could help.

Cluster is using MSCluster namespace. So what you can do is that
instead of retrieving class instance, you can run list against this
namespace:
Get-WmiObject -Namespace "Root\MSCluster" -List

Let me know if it helps,
Martin

Hi, Martin,

Get-WmiObject -Namespace "Root\MSCluster" -List  returns a list of classes 
even from a non-clustered node.

I think it might be better to test if

Get-WmiObject MSCluster_Cluster -Namespace "Root\MSCluster" -eq $null

Thank you!
