We do periodic CBU activation for DR testing. At the end of a test, we turn off CBU and the extra CPs go away. By that time however we've shut down the DR systems that used them, and no extras have been configured online to the SDM/XRC systems. In other words, not quite the same situation.
I'm guessing that some LPARs on the 406 have more than three CPs online. It would be prudent ahead of time to configure offline any CPs beyond the count you will end up with. . .

We're going from a 406 to a 603 on our z196 processor soon, and we're not sure if zOS will disable three of the six CPU's automatically, or if we have to do something ourselves. Same z196 machine or new machine? It depends.
