Decommission old vCenter Server 6.0 Appliance from Platform Services Controller

I deployed a temporary vCenter Server 6.0 Appliance to my existing lab to test the cross vCenter vMotion functionality across three vCenter appliances.  Once I validated this I no longer had the need for the VCSA and didn't want it taking up valuable resources in my lab.  My OCD also kicked in and I wanted to get rid of the associated error message that displayed within the web client:

As a good techie I searched for the solution but not couldnt find anything.  I posted the issue to twitter and legend William Lam (Blog | Twitter) was kind enough to post a link to a VMware KB article that explained the command:

If you've done what I've done and forgotten which VCSA was the PSC when you SSH in it should tell you at the logon screen:

After following the KB article I was able to successfully remove the decommissioned VCSA from the PSC and I no longer receive the warning within the Web Client.  I did have a slight hiccup in that the name of the VCSA in the error above was in capitals but inside the component manager database it was all lower case so the command had to be in lower case
