There were errors during the remediation operation

I wanted to work with vSphere Replication today, to write an article on it in fact, but first I had to upgrade everything to vSphere 5.5 Update 2.  The vC I use is the vCSA so that upgrade was easy and smooth.  But when I went to use VUM to upgrade my hosts I had the error mentioned above returned very quickly.


It was confusing so I checked the events and found this.


Where I saw quite clearly that I had forgotten to do something.


I forgot to enable the disable HA admission control.  Once I did that the VUM update went great.

I made this mistake to empower you to avoid it.
