To move resources using a DR file, code only the names of the PUs you want to move. Do not code associated LUs. VTAM® automatically includes the associated LUs in the move. For each PU, you can optionally specify a new SDLC link station address and whether you want the PU and its LUs automatically activated after the move. Figure 3 shows how to code a DR file to move PUs and LUs.

To change the SDLC link station address for a physical unit on a certain line, use the MOVE statement and specify the new address for the ADDR operand. Keep the FROM and TO line the same.

The MOVE operation through a DR file is only for PUs (and their associated LUs). To move an individual LU to another PU, use DELETE and then a subsequent ADD. (For efficient storage management, code all DELETEs before their related ADDs.)
