Feature codes for z/OS Metro/Global Mirror Incremental
Resync (RMZ Resync)
When you order the z/OS Metro/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
7684 feature and one 7682 feature.
Note: If you have an active z/OS Metro/Global Mirror feature and replace it with
an inactive feature, “Managing a licensed feature” on page 187 provides
information should you decide to use the feature again.
Table 47 provides the feature codes for z/OS Metro/Global Mirror Incremental
Resync (RMZ Resync) System z functions.
