Configuring dependent logical unit requester

Depedent logical unit requester (DLUR) allows dependent secondary logical units (LU 0, 1, 2, and 3) an entry point into the APPN network. DLUR support gives the appearance of having an adjacent connection to Virtual Telecommunications Access Method (VTAM®), but allows traversing the APPN network through intermediate nodes.

Note: DLUR uses logmode CPSVRMGR. This is created internally as part of the APPN and DLUR support. If CPSVRMGR exists as a user-defined logmode on any of the systems in your network, it must be deleted. Use the Work with Mode Descriptions (WRKMODD) command and specify the option to delete CPSVRMGR.
To configure the IBM i server to communicate with DLUR, follow these steps:
  1. Configure a host controller description.
  2. Configure device descriptions.
  3. Verify that an APPN connection into the network exists (host or APPC controller with *YES specified for the APPN parameter).
