Independent LUs

z/OS Communications Server: SNA Network Implementation Guide
SC27-3672-01

Independent LUs are represented to VTAM® as cross-domain resources (CDRSCs). Independent LUs can be coded with LOCADDR=0 in major nodes, coded as CDRSCs, or dynamically defined, but in all cases, VTAM represents them as CDRSCs. The independent LUs can access the network from multiple adjacent link stations, which can be in any domain. Even if you predefine independent LUs in device-type major nodes (NCP, local SNA, and switched major nodes), VTAM converts these definitions to CDRSCs when the major node is activated. Because independent LUs are represented as CDRSCs, when you use a DISPLAY command on an independent LU, the VTAM message responds with TYPE=CDRSC. However, message IST1131I shows a device type of INDEPENDENT LU / CDRSC.
