Failed to run vdcpromo when attempting to add PSC to embedded controller

[wreedctd]

Hello,

I am attempting to add a external PSC to my embedded Vcenter so I can join my existing vCenter to it and then use Linked Mode.

I am following these directions:

vSphere 6.0 Documentation Center

Problem is a get a error when attempting to join the new external PSC to the embedded PSC. See attached. Any ideas?

I was getting the error "leave federation cleanup failed. error 13 - confidentiality required" when trying to run the "vdcleavefed" command after a failed PSC installation. 

I attempted to install 6.0 U2, but my current embedded vcenter was running U1. 

So after the failed install, i wasn't able to decommission my failed PSC.  So I just reattempted the installation with U1, and it worked! 

Hope this helps someone.
