IBM DS6000 Series Point-in-Time Copy function PTC, Remote Mirror and Copy functions RMC, 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.

8.3.2Point-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 8-3provides the feature codes for the Point-in-Time Copy function.

Table 8-3 Point-in-Time Copy (PTC) feature codes

Feature code	Description
5200	PTC-1TB unit
5201	PTC-5TB unit
5202	PTC-10TB unit
5203	PTC-25TB unit
5204	PTC-50TB unit

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 8-4provides the feature codes for the Remote Mirror and Copy functions.
