PowerCLI Script to change path policy for RDMs

Hi,

I am trying to change the path policy setting for the Raw Device Mappings (RDMs) in our environment from "Round Robin" to "Fixed". We are using RDM LUNs for clustering, but it turns out that VMWare currently doesn't support Round Robin path policy in RDMs. I found many scripts to change the setting for all LUNs, but I just want to change the setting for RDMs and nothing else.

Any ideas on how to write a powercli script to do that would be greatly appreciated!

Thanks,
