Chapter 9. Managing and activating licenses
Managing and activating licensed functions is your responsibility.
Management refers to the use of the IBM Disk Storage Feature Activation (DSFA)
website to select a license scope and to assign a license value. You can perform
these activities and then activate the function.
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.
Activation refers to the retrieval and installation of the feature activation code into
the DS8000 system. The feature activation code is obtained using the DSFA website
and is based on the license scope and license value.
You perform these activities at the following times:
v After the IBM service representative has installed your storage unit and before
you configure it
v
When you increase the extent of the function authorization for a licensed
function (that is, you add additional capacity to your license)
To perform these activities, you must access the DSFA website at:
www.ibm.com/storage/dsfa
When you access DSFA, you must enter information about your DS8000 storage
unit so the web application can access the correct function authorization records.
You can find the information you must enter into DSFA on the Storage Unit
General Properties page in the IBM System Storage DS Storage Manager
application.
Planning your licensed functions
As you plan for your licensed functions, it is important to consider increases in
your workload requirements. To provide more flexibility with licensing,
usage-based licensing is supported with the DS8800.
With the introduction of the DS8800, functions such as Parallel Access Volumes
(PAVs) and advanced Copy Services functions such as FlashCopy, Metro Mirror,
and Global Mirror are priced based on the usage of license capacity you purchase.
For example, when you purchase licensed features for these functions, the features
no longer have to be purchased with the same license capacity. You can purchase
licenses for Copy Services functions with individual capacities instead of having to
buy the licensed features with a single capacity. This capability is designed to
provide you with more flexible and optimal price and performance configurations.
With the usage-based license capability comes the requirement to plan how much
storage capacity you will require for future growth. As you plan for your licensed
functions, it is important to consider increases in your workload requirements. For
example, consider the following guidelines, which include but are not limited to:
