Chapter 5. Planning use of licensed functions
Licensed functions are the storage unit system operating system and functions.
Required features and optional features are included.
IBM authorization for licensed functions is purchased as 239x machine function
authorizations. However, the license functions are actually machine models. For
example, the operating environment license (OEL) is listed as a 239x Model LFA,
OEL license (242x machine type). The 239x machine function authorization features
are for billing purposes only.
239x function authorization models (242x machine types)
To establish the extent of IBM authorization for a licensed function, you purchase a
function authorization model by ordering a specific feature code that indicates the
size, in terabytes (or TBs, where 1 TB equals 1,000,000,000,000 bytes), of the extent
of IBM authorization.
The function authorization model size (or level) represents physical capacity. The
total authorization level for a given licensed function is the sum of the TBs
associated with all the purchased feature numbers.
Function authorizations are purchased for the DS8000 base model and they
establish the authorization level for the entire storage unit (base model plus any
expansion models). The operating environment license authorizations (239x Model
LFA, OEL license) must be authorized for the full physical capacity of the storage
unit. When you order optional licensed functions, you purchase a license for a
specific authorization level (a specific number of TBs) for the storage unit.
Note: If you are activating features for any of the licensed functions, such as Copy
Services, all the features must have the same capacity, including the
operating environment license feature.
After you purchase the function authorizations, you manage and activate the
functions through the following IBM Disk Storage Feature Activation (DSFA)
website:

Licensed function indicators
Each licensed function indicator feature that you order on a DS8000 series base
unit enables that function at the system level.
After you receive and apply the IBM feature activation keys for the licensed
function indicators, your functions are enabled for you to use. The license function
indicators are also used for maintenance billing purposes.
DS8000 Series Function Authorization (242x machine type or 239x functional
authorization machine type) feature numbers must be purchased to establish the
extent of IBM authorization for the licensed function before the feature activation
code is provided by IBM.
