DRS VM affinity/anti-affinity rules - these are lost when DRS is disabled - they can be "listed" via perl script or VI Toolkit for manual re-entering if needed ...
But can they be backed up / restored via automated methods for easy restoration in case of required or accidental disabling of DRS? What if a vCenter user disables instead of setting to manual during operations?
I have over 100+ DRS VM affinity/anti-affinity rules to maintain.
