Chapter 5. Licensed functions
Licensed functions are the operating system and functions of the storage system. Required features and
optional features are included.
IBM authorization for licensed functions is purchased as 533x or 904x machine function authorizations.
However, the license functions are storage models. For example, the Base Function license is listed as a
533x or 904x model FF8. The 533x or 904x machine function authorization features are for billing
purposes only.
The following licensed functions are available:
Base Function
The Base Function license is required for each storage system.
z-synergy Services
The z-synergy Services include z/OS licensed features that are supported on the storage system.
Copy Services
Copy Services features help you implement storage solutions to keep your business running 24 hours
a day, 7 days a week by providing data duplication, data migration, and disaster recovery functions.
Copy Services Manager on Hardware Management Console
The Copy Services Manager on Hardware Management Console (CSM on HMC) license enables IBM
Copy Services Manager to run on the Hardware Management Console, which eliminates the need to
maintain a separate server for Copy Services functions.
Licensed function indicators
Each licensed function indicator feature that you order on a base frame enables that function at the
system level.
After you receive and apply the feature activation codes for the licensed function indicators, the licensed
functions are enabled for you to use. The licensed function indicators are also used for maintenance
billing purposes.
Note: Retrieving feature activation codes is part of managing and activating your licenses. Before you can
logically congure your storage system, you must rst manage and activate your licenses.
Each licensed function indicator requires a corequisite 904x function authorization. Function
authorization establishes the extent for the licensed function before the feature activation code is
provided. Each function authorization applies only to the specic storage system (by serial number) for
which it was acquired. The function authorization cannot be transferred to another storage system (with a
different serial number).
License scope
Licensed functions are activated and enforced within a dened license scope.
License scope refers to the following types of storage and types of servers with which the function can be
used:
Fixed block (FB)
The function can be used only with data from Fibre Channel attached servers. The Base Function,
Copy Services, and Copy Services Manager on the Hardware Management Console licensed functions
are available within this scope.
