Note: Subcapacity licensing is available as an RPQ. For more information, see your IBM
representative.
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 unit. This activity
is performed using the Disk Storage Feature Activation (DSFA) website:
