Activating Licensed Functions; Obtaining Activation Codes - IBM DS8800 Introduction And Planning Manual

v Plan for disk space allocation. Determine your typical disk storage requirements
v Estimate the amount of capacity you need for current and future Copy Services
Recognizing that both your storage and data requirements will increase over time
and that capacity and performance planning is your responsibility, purchase and
manage your licensed functions for maximum utilization. It can also be more cost
effective to purchase more storage capacity to ensure that the maximum usage of
your licensed features does not exceed the allowed capacity of that which was
purchased. Ensure that you manage and purchase your licensed functions for
maximum utilization. Should this happen, IBM will be notified that the usage
exceeds the allowed capacity on any given licensed feature. You will be notified by
IBM and required to extend enablement of your licensed feature and install a new
licensed feature key.

Activating licensed functions

After the IBM service representatives have completed your DS8000 storage
complex installation, your first step is to activate your licensed functions.
To activate your licensed functions, you must perform the following actions:
v Obtain your feature activation codes.
v Apply the activation codes to your storage unit. You can apply the activation
The initial enablement of any optional DS8000 licensed function is a concurrent
activity (assuming that the appropriate level of microcode is installed on the
machine for the given function).
Note: The following activities are non-disruptive, but take effect at the next

Obtaining activation codes

Complete this task to obtain your feature activation codes for the licensed features
for each storage unit. To obtain your activation codes, you must connect to the IBM
Disk Storage Feature Activation (DSFA) website.
Before you can connect to the site, ensure that you have the following items:

v A lateral change or reduction in the license scope. A lateral change is
defined as changing the license scope from fixed block (FB) to count key
data (CKD) or from CKD to FB. A reduction is defined as changing the
license scope from all physical capacity (ALL) to only FB or only CKD
capacity.
