vCenter

Getting an error when unregistering a PSC.

Our environment has 4 sites running Linked-Mode.  Each site has 3 guests.... 1 vCenter, 1 PSC and 1 SQL.  Sites 2, 3 and 4 partner back to the PSC at site 1.  We are shutting down site 2.

I'm following VMware KB 210736.  I stopped the PSC service at site 2, then  on that PSC ran cmsso-util to unregister the vCenter, which was successful.  Then I went to the PSC at site 4 and ran cmsso-util to unregister the PSC at site 2, but received an error.  A bit confusing..... displays error 1, but then shows Success.

Below is the cmsso-util output.  I believe I need to run vdcleavefed -h -u -w to force a rip-out of the machine account, but need someone to verify if that is correct.  If it is, where do I run vdcleavefed ?  From the PSC at site 4 or on the PSC at site 2 (the one being removed) ?  Thanks in advance for any help.

D:\Program Files\VMware\vCenter Server\bin>cmsso-util unregister --node-pnid km-

001-psc01.minoltana.minolta.com --username administrator@vsphere.local --passwd

Worked through the problem(s) with some help from VMware Support.  Found documentation on un-registering vCenter\PSC somewhat sparse and\or confusing.  Was following VMware KB 2106736.  Make sure to stop the PSC service before doing unregister vCenter.  The vCenter step is on the last page of the KB.... not sure why..  I guess I needed to read between the lines, which I didn't do.  The other item that caused an issue was having to re-point one of the 4 PSCs in Linked mode.  Finally in the end cmsso-util still threw an error....... Had to run the vdcleavefed command to force a rip out of the machine account.  All appears to be working well now.
