I found that document:
vSphere Documentation Center
and tried to do so. But I get this message after the Creating of the Cluster:
Cannot recover VSA cluster: Error seen: Adding hosts to HA Cluster failed.
Move host into cluster VSA HA Cluster
The host cannot be admitted to the cluster's current Enhanced vMotion Compatibility mode.
Powered-on or suspended virtual machines on the host may be using CPU features hidden by that mode.
If I create that cluster by hand I can insert the hosts without any error and HA works, but there is no VSA seen in the VSA Manager.
What can I do?
Thank you for your help.
