I've looked at documentation but haven't found a clear answer. I have a primary VCSA 6.7 that I want to enable HA on to get those benefits. However, I have not found if the process causes any sort of outage for vCenter.
I'd like to do this during a time of my choosing, but that requires a confirmation to management of no outage. If I can't give that assurance, then I'll have to schedule it during a standard outage window that is inconvenient to me.
Does anyone know? Have you performed the process and can confirm one way or the other?
Moderator: Thread moved to the vCenter Server area.
I have several times enables or disabled vCenter HA in a production environment, there is no outage.
And from my experience i can say: Don't use the H5 client, use the flash client for the inital setup.
As Raudi said, there is no downtime...
But if you want to see it by yourself, the next is the official video of the feature in a walkthough of the configuration process (you will se that there is no outage)
