The following scenario illustrates how you could configure the RRSF network shown in Figure 1 .

Figure 1. An RRSF network containing a multisystem node and a single-system node. NODEAB is a multisystem node. NODEX is a single system node.

In this network, MVSA and MVSB share a RACF® database, and are configured as member systems of multisystem node NODEAB. MVSA is the main system on NODEAB. MVSX has its own RACF database, which it does not share with any other system, and is configured as a single-system RRSF node, NODEX. APPC/MVS is active on all nodes. MVSA has the LU name LU0A, MVSB has the LU name Lube and MVSX has the LU name LU0X. The dotted lines represent RRSF communication.
