License scope refers to the following types of storage and types of servers with
which the function can be used:
Fixed block (FB)
The function can be used only with data from Fibre Channel attached
servers. The Base Function, Copy Services, and Copy Services Manager on
the Hardware Management Console licensed functions are available within
this scope.
Count key data (CKD)
The function can be used only with data from FICON attached servers.
The Copy Services, Copy Services Manager on the Hardware Management
Console, and z-synergy Services licensed functions are available within this
scope.
Both FB and CKD (ALL)
The function can be used with data from all attached servers. The Base
Function, Copy Services, and Copy Services Manager on the Hardware
Management Console licensed functions are available within this scope.
Some licensed functions have multiple license scope options, while other functions
have only a single license scope.
You do not specify the license scope when you order function authorization feature
numbers. Feature numbers establish only the extent of the IBM authorization (in
terms of physical capacity), regardless of the storage type. However, if a licensed
function has multiple license scope options, you must select a license scope when
you initially retrieve the feature activation codes for your storage system. This
activity is performed by using the IBM Data storage feature activation (DSFA)
website (www.ibm.com/storage/dsfa) .
Note: Retrieving feature activation codes is part of managing and activating your
licenses. Before you can logically configure your storage system, you must first
manage and activate your licenses.
When you use the DSFA website to change the license scope after a licensed
function is activated, a new feature activation code is generated. When you install
the new feature activation code into the storage system, the function is activated
and enforced by using the newly selected license scope. The increase in the license
scope (changing FB or CKD to ALL) is a nondisruptive activity. A reduction of the
license scope (changing ALL to FB or CKD) is a disruptive activity, which takes
effect at the next restart.
Ordering licensed functions
After you decide which licensed functions to use with your storage system, you
are ready to order the functions.
About this task
Licensed functions are purchased as function authorization features.
To order licensed functions, use the following general steps:
Procedure
1. Required. Order the Base Function license to support the total physical capacity
of your storage system.
