This is an interesting feature, and I am looking at it to help out IT at work (plus I am curious). But, I am finding not much info, and some conflicting info. I am going to write up what I think is right and add a few questions and we will see if anyone knows more than me.
Proactive HA is part of DRS, and you can configure it to suggest migration recommendations or put a host into Maintenance Mode (MM) when certain events events happen. These events are not a host dying where HA would help but rather smaller things like the list below:
- Power Supply
However in the 6.7 vSphere documentation it has no list of things like above. It just has info on enabling it.
The documentation also implies you need to have a vendor provider file that is what surfaces this info. When I heard about this feature under development a really long time ago, I believe that vendors did have to do some work. So here is a list that may be right:
I have enabled this feature on my SuperMicro gear and it did not say no, or you are missing a provider but I suspect it will not work. Wait, I now see – since I am on a computer now with a big screen rather than an iPad, that there is – in the details are a comment “No response because no Proactive HA provider is enabled on this cluster.” I think that this confirms the need for the provider!
- 10/14/19 – I have seen in several places where it implies or suggests that the provider is installed as part of the vSphere Web Client plug-in. So both of the names on my list above have that. So things may work with them.
I will update this article as people correct me, or provide additional info, and I really appreciate and and all help.
