Don't know if this got resolved, but I ran into the same problem. The fix was to make sure vmware platform is chosen, and sometimes one of the ports will not take all of the check boxes, which need to be as follows:
You get there through host groups, edit the host group, then change options, about halfway down is a set of checkboxes, ensure these are checked on all ports the volumes are presented on.
