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.
