Figure 9-6 Remote Mirror and Copy

Global Mirror requires both RMC and PTC functions. Both primary and secondary storage units require RMC functions and the secondary requires PTC functions as well. If Global Mirror will be used during failback on the secondary storage unit, a Point-in-Time Copy function authorization must also be purchased for the primary system.

RMZ and PAV are only applicable to zSeries, so you will only have CKD data. In RMZ configurations that exploit the failback technique, you will have to purchase a license feature for the secondary storage unit too.

The initial enablement of any optional DS8000 licensed function is a concurrent activity (assuming the appropriate level of microcode is installed on the machine for the given function). The removal of a DS8000 licensed function to deactivate the function is a disruptive activity and requires a machine IML.

9.3.7 Disk storage feature activation

Managing and activating licensed functions is your responsibility. You manage and activate functions through the IBM Disk Storage Feature Activation (DSFA) Web site at:

http://www.ibm.com/storage/dsfa

Management refers to the use of the IBM Disk Storage Feature Activation (DSFA) Web site to select a license scope and to assign a license value. You perform these activities and then activate the function.
