The Group Definitions section functions as an index to your customized Group Sections. It contains a complete list of all the Groups and their Group Sections which contain your customized settings.
All Groups can point to the same Group Section. All Groups can point to different Group Sections. Any combination of Groups can use the same Group Section or a unique Group Section. The only rules are that all Groups must be coded and a Group cannot point to a Group Section that does not exist.
The value coded for each Group attribute can be customized to any name that allows you to easily identify the purpose of the Group. The sample names provided document how each Group will backstore its Virtual Volumes: Primary_Only, Primary_Duplex, and so on. Group Section names like Test_Primary_Not_Encrypted, Prod_Primary_Duplex_Encrypted, and so on, can be used to self document what data is being written to a Group, how it will be backstored, and other important details.
The customized Group Section name must be coded inside less than and greater than signs (<Customized_Group_Section_Name>) somewhere in the same parmlib member as the Group Definitions Section.
The valid values and description of the Group Definitions Groupnn= attribute is as follows:
