VMware vSphere 4.x error ‘The datastore is connected to one or more hosts that do not support Storage I/O Control’

When selecting the ‘Enabled’ checkbox in the properties of your datastore, you might receive the error “The datastore xxxx is connected to one or more hosts that do not support Storage I/O Control”.

This might seem weird (it did to me), because you installed all patches and maybe even already run vSphere 4.1. The answer is displayed here. Yes indeed, you need the most expensive vSphere license to enable this. Bummer 😦

    thanks for the post – we seem to have the same problem and the error message is not vastly helpful – your blog was.

    sorry but link is broken. It takes you to vmwarestore,
    Can you please re-post?

    One could have have spent hours trying to figure out which host in the cluster doesn’t support Storage I/O. Your post helped me figure that it’s all of them.
    Thanks!!
