Dynamic reconfiguration and independent LUs

You can create and alter CDRSC major nodes as needed to effect the same level of support as dynamic reconfiguration provides. Because dynamic reconfiguration has meaning only if the independent LUs are predefined using LU definitions, it is no longer needed when you convert your independent LU definitions to CDRSCs.

Note: The ISTPDILU major node contains CDRSC definitions for independent LUs that are converted from LU definition statements by VTAM®. The ISTPDILU major node is automatically activated by VTAM on initialization and cannot be activated or deactivated by operator commands.

When processing a dynamic reconfiguration definition that contains an independent LU definition to be added, VTAM converts that independent LU to a CDRSC and places it in the ISTPDILU major node. The PU named on the TO operand becomes an entry in the CDRSC default adjacent link station list.

If you specify a PU on the FROM operand of the dynamic reconfiguration DELETE command on an independent LU, VTAM deletes the network address associated with that independent LU that was predefined for that independent LU. Additionally, the PU is removed from the default adjacent link-station list if present.

To use the dynamic reconfiguration DELETE command on an independent LU, the independent LU must not have any sessions over the PU named on the FROM operand.

You cannot use the MODIFY DR command for independent LUs.
