IBM TotalStorage DS6000 Series - Manual (Page 157)

Chapter 8. Configuration planning 133
The deactivation of an activated licensed function, or a lateral change or reduction in the
licensed scope, is a disruptive activity and requires an initial microcode load (IML). A lateral
change occurs when the user changes license scope from CKD to FB or FB to CKD. A
reduction in license scope also occurs when the user decides to change from a license scope
of ALL to CKD or FB.

8.3.2 Point-in-Time Copy function (PTC)
The Point-in-Time Copy licensed function model and features establish the extent of IBM
authorization for the use of IBM TotalStorage FlashCopy. When you order Point-in-Time
Copy functions, you specify the feature code that represents the physical capacity to
authorize for the function.
Table 8-3 provides the feature codes for the Point-in-Time Copy function.
Table 8-3 Point-in-Time Copy (PTC) feature codes
You can combine feature codes to order the exact capacity that you need. For example, if you
determine that you need 23 TB of point-in-time capacity, you can order two 5202 features (this
will give you 20TB) and three 5200 features (this will give you 3TB), giving you a total of 23TB.
8.3.3 Remote Mirror and Copy functions (RMC)
The Remote Mirror and Copy licensed function model and features establish the extent of
IBM authorization for the use of the Metro Mirror (Synchronous PPRC), Global Mirror
(Asynchronous PPRC) and Global Copy (PPRC Extended Distance).
Table 8-4 provides the feature codes for the Remote Mirror and Copy functions.
