by the copy process. In addition, Copy Services solutions that require multiple
copies of data can also require extensive capacity storage.
Recognizing that both your storage and data requirements will increase over time
and that capacity and performance planning is your responsibility, ensure that you
purchase and manage your licensed functions for maximum usage. It can be more
cost effective to purchase more storage capacity to ensure that the maximum usage
of your licensed functions does not exceed the allowed capacity of the storage that
was purchased. If the capacity is exceeded, IBM is notified that the usage exceeds
the allowed capacity on any given licensed function. You are notified by IBM and
required to extend enablement of your licensed function and install a new licensed
feature key.
Activation of licensed functions
After the technical service representatives complete your DS8000 series installation,
your first step is to activate your licensed functions.
To activate your licensed functions, complete the following actions.
v Obtain your feature activation codes.
v Apply the feature activation codes to your storage system. You can apply the
feature activation codes by importing a downloadable file from the IBM Data
storage feature activation (DSFA) website (www.ibm.com/storage/dsfa) .
The initial enablement of any optional DS8000 licensed function is a concurrent
activity (assuming that the appropriate level of microcode is installed on the
storage system for the function).
Note: Removal of a DS8000 licensed function to deactivate the function is
non-disruptive, but takes effect at the next IML.
Activating licensed functions
You must obtain feature activation codes for the licensed features for each storage
system by connecting to the IBM Disk Storage Feature Activation (DSFA) website.
Before you begin
Before you can connect to the site, ensure that you have the following items:
v
A removable media for downloading your feature activation codes into a file.
Use the removable media if you cannot access the Storage Manager from the
system that you are using to access the DSFA website. Instead of using
removable media, you can also write down the activation codes and then
manually enter them into the system that runs the Storage Manager.
v The system serial number, model, and signature.
Notes:
1. Enabling an optional licensed function is a concurrent activity (assuming the
appropriate level of microcode is installed for the function). The following
activating activities are non-disruptive, but take effect at the next IML:
v
Removal of a licensed function for its deactivation.
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.
