Feature codes for remote mirror and copy

When you order remote mirror and copy functions, you specify the feature code that represents the physical capacity to authorize for the function.

Note: If you are activating features for any of the licensed functions, such as Copy Services, all the features must have the same capacity, including the operating environment license feature.

The remote mirror and copy license feature codes enable the use of the following remote mirror and copy (RMC) licensed functions:

IBM^® System Storage™ Metro Mirror (MM)
IBM System Storage Global Mirror (GM)
IBM System Storage Metro Global Mirror (MGM)

The feature codes are authorized based on physical capacity.

If you plan to use this licensed function with fibre-channel attached servers, the total authorization level must be greater than or equal to the total physical capacity of the storage unit that will be logically configured as FB.
If you plan to use this licensed function with FICON^® attached servers, the total authorization level must be greater than or equal to the total physical capacity of the storage unit that will be logically configured as CKD.
If you plan to use this licensed function with both fibre-channel and FICON attached servers, the total authorization level must be greater than or equal to the total physical capacity of the storage unit.

Remote mirror and copy features must be purchased for both the primary and secondary DS6000™ systems.

Remote mirroring solutions require the installation of at least one fibre-channel or FICON host port on each DS6000 system in the remote mirroring configuration to serve as the communications link between the primary and secondary machines. For higher availability, use more than one host port per DS6800 be used for the remote mirroring connectivity.

The fibre-channel ports used for remote mirror and copy can be configured as either a dedicated remote mirror link or as a shared port between remote mirroring and FCP data traffic.

Remote mirror and copy solutions are supported with the use of SAN fabric products, Dense Wavelength Division Multiplexing (DWDM) products, and channel extenders. To see a current list of supported environments, configurations, networks, and products, see the DS6000 series Interoperability Matrix at:

Vendors must be consulted in regards to hardware and software prerequisites when using their products on the DS6000 system remote mirror and copy configuration. IBM is not responsible for third-party products.

IBM supports the use of remote mirror and copy over the network technologies that are currently supported by the channel extender products, including Fibre Channel, Ethernet/IP, ATM-OC3, and T1/T3. Evaluation, qualification, approval, and support of remote mirror and copy configurations using channel extender products are the sole responsibility of the channel extender vendor. The vendor should be contacted to obtain information about its distance capability, line quality requirements, as well as SAN and WAN attachment capabilities.

Global Mirror has the following additional prerequisites:

The point-in-time copy function must be purchased for the secondary DS6800 system.
If Global Mirror is used during failback on additional DS6800 machines, the point-in-time copy function authorization must also be purchased for the primary DS6800 machine.

In the event of a planned or unplanned outage, recovery procedures are required to achieve a consistent and restartable copy of the data at the remote site. Scripts and software can be used to help automate these procedures.
