Figure 1 shows three MVS™ systems called PRIMARY, TEST, and BACKUP2. PRIMARY is on one processor and TEST and BACKUP2 are in LPARs on a PR/SM™ processor. PRIMARY and BACKUP2 are in the same sysplex and are connected through the same coupling facility. TEST is not in the sysplex. In the example, the group members of the multisystem applications on PRIMARY need more processor storage resources than their group members on BACKUP2.
