Base Function license

The Base Function license provides essential functions for your storage system. A Base Function license is required for each storage system.

The Base Function license is available for the following license scopes: FB and ALL (both FB and CKD).

The Base Function license includes the following features:
  • Database Protection
  • Encryption Authorization

The Base Function license feature codes are ordered in increments up to a specific capacity. For example, if you require 160 TB of capacity, order 10 of feature code 8151 (10 TB each up to 100 TB capacity) and 4 of feature code 8152 (15 TB each, for an extra 60 TB).

Base Function license rules

The Base Function license authorizes you to use the model configuration at a specific capacity level. The Base Function license must cover the full physical capacity of your storage system, which includes the physical capacity of any expansion frames within the storage system. The license capacity must cover both open systems data (fixed block data) and IBM® Z data (count key data). All other licensed functions must have a capacity that is equal to or less than the Base Function license.

Note: Your storage system cannot be logically configured until you activate the Base Function license. On activation, drives can be logically configured up to the extent of the Base Function license authorization level.

As you add more drives to your storage system, you must increase the Base Function license authorization level for the storage system by purchasing more license features. Otherwise, you cannot logically configure the additional drives for use.
