VMware PSC in HA script
VMware has released a script, that makes it a lot easier to configure the Platform Services Controller (PSC) in High Available (HA) configuration.
These scripts can be used for both the vCSA (Appliance) and Windows version.
You can find the scripts here: https://my.vmware.com/web/vmware/details?downloadGroup=PSCHA600&productId=491
There is a white paper on how to configure this using the scripts, you can find it here: http://www.vmware.com/content/dam/digitalmarketing/vmware/en/pdf/techpaper/vmware-vcenter-server6-deployment-guide-white-paper.pdf
