For example a 9048-FF8 designates a DS8000 Licensed Function Authorization for a 5333 machine with a three-year warranty period. 

GLYPH<SM590000> The licensed function indicator feature numbers enable the technical activation of the function, subject to a feature activation code that is made available by IBM and applied by the client. The 904 y -FF8 ( y =6 - 9) licensed function authorization feature numbers establish the extent of authorization for that function on the 533 x -99 z  ( x =1 - 4, z =3 - 6) machine for which it was acquired. 

GLYPH<SM590000> Licensed functions are activated and enforced with a defined license scope. License scope refers to the type of storage and the type of servers, that the function can be used with. For instance, the zsS licenses are only available with the count key data (CKD) (z/FICON) scope. 

The base functions are mandatory. The base functions must always be configured for both mainframe and open systems, which is a scope of ALL . Also, to configure CKD volumes, the activation of Feature Code 8300 is required. 

With CS, if these services are only used for either mainframe or  open systems, the restriction to either FB or CKD is possible. However, most clients will want to configure CS for scope ALL . 

For each group of licensed functions, specific feature code numbers indicate the licensed capacity, as shown in Table 9-2. These feature codes vary depending on model. Also, see “Ordering granularity” on page 238.

## 9.1.1 Licensing general introduction 

Several of the orderable feature codes must be activated through the installation of a corresponding license key bundle. These feature bundle codes are listed in Table 9-1 on page 232. Certain features can be configured directly for the client by the IBM marketing representative during the ordering process.
