Chapter 10. License activation and management
The management and activation of licensed functions are responsibilities that are
associated with the role of your storage administrator.
Management refers to the use of the IBM Data storage feature activation (DSFA)
website (www.ibm.com/storage/dsfa) to select a license scope and to assign a
license value. You can complete these activities and then activate the function.
Activation refers to the retrieval and installation of the feature activation code into
the storage system. The feature activation code is obtained by using the IBM Data
storage feature activation (DSFA) website (www.ibm.com/storage/dsfa) and is
based on the license scope and license value.
You complete these activities at the following times:
v After the technical service representative installs your storage system, and before
you configure it.
v When you increase the extent of the function authorization for a licensed
function (that is, you add more capacity to your license).
To complete these activities, access the IBM Data storage feature activation (DSFA)
website (www.ibm.com/storage/dsfa).
When you access the DSFA website, you must enter information about your
storage system so the web application can access the correct function authorization
records. You can find this information either by clicking Need Help in the Activate
Licensed Functions page or by selecting Properties on the System page of the
DS8000 Storage Management GUI.
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, use-based
licensing is supported on the storage system.
The Base Function license is based on the entire capacity of the storage system.
The z-synergy Services, Copy Services, and Copy Services Manager on the
Hardware Management Console (HMC) licenses are priced based on the use of
license capacity that you purchase.
With the use-based license capability comes the requirement to plan how much
storage capacity you 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:
v Plan for storage space allocation. Determine your typical storage requirements
and consider how much more storage you would need if you have rapid or
unpredictable growth.
v
Estimate the amount of capacity you need for current and future Copy Services
functions. For example, consider the number of target volumes you need for
FlashCopy relationships at remote sites. As the number of FlashCopy target
volumes increase, more available bandwidth of the disk system might be used
