CA Top Secret how to remove a CPF NODE from the NDT table?
 
Answer:
If you don't plan on bringing that system back up, you should deactivate the connection to that system on the other systems. 
TSS REM(*CPFRECV) CPFNODE(node) and then do a TSS MODIFY(CPF(REFRESH)) 

Note: 
This is if you do not want command to go to the system taken  off-line 
because once  REMOVED they are gone.
