• Advanced Extension (FTR_AE)
Required for multiple-circuit tunnels, FCIP Trunking, Adaptive Rate Limiting, and other FCIP
features. Advanced Extension is not required for FICON Acceleration features, but multiple
circuits could be used in a FICON emulation environment. This is a slot-based license for
extension switches and blades.
This license contains the following options:
‐ Capacity 1

‐ Configured Blade Slots 1
ATTENTION
Use the licenseShow command to verify the licenses are installed on the hardware at both ends of

IBM z/OS Global Mirror emulation
The IBM z/OS Global Mirror emulation (formerly eXtended Remote Copy or XRC) application is a
direct-attached storage device (DASD) application that implements asynchronous disk mirroring, as
supported by the disk hardware architecture and a host software component called System Data
Mover (SDM). Within this application, a specific application channel program invokes a well-
constrained type of channel program called a Read Record Set (RRS) channel program. This channel
program is used to read only updates to disk volumes (record sets) after they have been brought into
synchronization with the aim of writing only record updates to a mirrored volume. The RRS channel
program accesses primary volumes from a remote host for the purpose of reading these record sets
(updates) supported by IBM z/OS Global Mirror emulation. The emulation feature thus allows the
