Figure 8-6 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 on the primary system.
PAV is only applicable to zSeries, so you will only have CKD data.
The initial enablement of any optional DS6000 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 DS6000 licensed function to deactivate the function is a disruptive
activity and requires an IML.
8.3.7 Disk storage feature activation
Managing and activating licensed functions is the client’s responsibility. The client can
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. The client performs these activities and
then activates the function.
Activation refers to the retrieval and installation of the feature activation code into the DS6000
system. The feature activation code is obtained using the DSFA Web site and is based on the
license scope and license value.
