If you are expanding a system, run the map analysis procedures at either of these times:
  • After the system expansion
  • Before the system expansion
Perform the following procedure only in the second case, when you ran the analysis procedures before the system expansion and are not going to run them again afterward.
  1. Rename the planned maps created with the CreateExpansionMaps procedure with the actual map names to be used in the Mover procedures. To do this, call PostExpansionAction. In the following example, you have expanded the system to 4 nodes and 40 AMPs. The PostExpansionMap contiguous map is called TD_Map1005:
    CALL TDMaps.PostExpansionAction(4, 'TD_Map1005');
