Fix Path Selection Policy for a whole vCenter Cluster

These last few weeks, I’ve been toying with PowerCLI (and PowerShell for that matter). One thing I do have to say, is that Microsoft finally did it right!

This works great, however you could make it work on the whole vCenter inventory, which I don’t want. We usually add LUNs to a single cluster at one time. Only thing you might need to change, is the canonical name. Mine simply says “find all SVC LUNs” and you might need to change it, if you’re using a different storage.
