Error adding new disk to VM

[SpunkyMonkey678]

Hi,

I recieve this error when trying to add a new disk in vCenter. This error happens when I choose any datastore in the cluster. See image for the screenshot. How do I fix this error, steps would be great too. Any help is greatly appreciated.

Thanks,

Jay

This seems because you have set affinity on Storage DRS.... you can see Cormac's blog regarding this options:
