Chapter 2. Planning use of licensed functions
Licensed functions are storage unit system operating system and software
functions. These include both required features and optional features.
The following categories represent the types of DS6000 series licensed functions
that are available.
v Operating environment licensing
v DS6000 series Copy Services
v Parallel access volumes
Feature codes for operating environment licensing
You must order an operating environment licensing (OEL) feature for every DS6000
series.
Table 1 on page 28 lists the operating environment licensing feature codes for the
DS6000 series.

You must order an operating environment license (OEL) for every DS6800
system. The extent of IBM authorization acquired through the DS6800 feature
numbers (50xx) must cover the physical capacity of the DS6800 system, where
system is defined as the base enclosure and all attached expansion enclosures.
The DS6000 series offers licensing options, which are available for the DS6800
FlashCopy (Point-in-Time Copy) feature numbers 52xx and Remote Mirror and
Copy feature numbers 53xx, as follows:
–
If the function is used with open systems data only, a license is required for
only the total physical capacity configured as Fixed Block (FB).
– If the function will be used with zSeries data only, a license is required for
only the total physical capacity configured as Count Key Data (CKD).
–
If the function is used with both open systems and zSeries data, a license is
required for the total physical capacity of the DS6800 system including the
DS6000 Expansion Enclosures.
In addition, the license scope (FB, CKD, or entire machine) is client managed
through an IBM Web-based application. This allows you to change the license
scope on a given machine as your business requirements change.
The parallel access volume (PAV) function is an optional feature (number 51xx)
that enables zSeries hosts to conduct multiple concurrent I/O operations. PAV
requires the purchase of the FICON attachment feature number 5915.
A PAV license authorizes the use of PAV at the specified capacity. The
authorization level provided by each feature number is stated within the feature
number description. The unit represents physical capacity, where a TB (terabyte)
equals one trillion bytes. The total authorization level for this licensed function is
the sum of the units (terabytes) associated with all the purchased feature
numbers.
These features can be purchased in any sequence or combination. The extent of
IBM authorization is increased by purchasing additional feature numbers.
This licensed function is authorized on the basis of physical capacity and has a
license scope of CKD. The total authorization level must be equal to or greater
than the total amount of physical capacity within the DS6800 system that will be
logically configured as CKD.
