z/OS licensed features
This section describes z/OS licensed features supported on the DS8000.
Remote mirror for z/OS (242x Model RMZ and 239x Model LFA,
RMZ license)
The remote mirror for z/OS licensed function model and features establish the
extent of IBM authorization for the use of the z/OS remote mirroring licensed
function on your storage unit.
The IBM System Storage z/OS Global Mirror function is a z/OS remote mirroring
licensed function.
Feature codes for z/OS Global Mirror
When you order the z/OS Global Mirror function, you specify the feature code
that represents the physical capacity to authorize for the function.
Note: If you are activating features for any of the licensed functions, such as Copy
Services, all the features must have the same capacity, including the
operating environment license feature.
You can combine feature codes to order the exact capacity that you need. For
example, if you determine that you need 30 TB of capacity, you would order one
7654 feature and one 7652 feature.
Note: If you have an active z/OS Global Mirror feature and replace it with an
inactive feature, see “Managing a licensed feature” on page 187 for
information about using the feature again.
Table 46 on page 135 provides the feature codes for remote mirror for System z
functions.
