A sysplex couple data set stores information about its systems, the XCF groups and members running in the sysplex, and general status information. Depending on the policies you define to help manage resources and workload for the sysplex, you need to define additional couple data sets to store policy-related information for coupling facility resource management (CFRM), sysplex failure management (SFM), automatic restart management (ARM), system logger (LOGR), and workload management (WLM).
You can use this panel to specify the prefix and the volumes for the primary, alternate, and spare couple data sets that the wizard uses in the couple data sets panel. You must specify all fields or use the defaults. You only see this panel the first time that you use the wizard. When you press Finish and reenter the wizard, the panel does not appear.
The prefix that you specify will be used to create the names of all the couple data sets for the Parallel Sysplex (sysplex, CFRM, SFM, ARM, LOGR, and WLM). Ensure that the prefix is already defined in a user catalog shared across the Parallel Sysplex.
If you have couple data sets defined and the wizard is able to access the information, those couple data set names and volumes are loaded into the couple data set tables on the next panels. Be sure that you define all couple data sets for the sysplex, CFRM, SFM, ARM, WLM, and LOGR.
