z/OS Global Mirror
z/OS Global Mirror (previously known as Extended Remote Copy or XRC)
provides a long-distance remote copy solution across two sites for open systems
and IBM Z data with asynchronous technology.
z/OS Metro/Global Mirror Incremental Resync
z/OS Metro/Global Mirror Incremental Resync (RMZ) is an enhancement for z/OS
Global Mirror. z/OS Metro/Global Mirror Incremental Resync can eliminate the
need for a full copy after a HyperSwap situation in 3-site z/OS Global Mirror
configurations.
The storage system supports z/OS Global Mirror that is a 3-site mirroring solution
that uses IBM System Storage Metro Mirror and z/OS Global Mirror (XRC). The
z/OS Metro/Global Mirror Incremental Resync capability is intended to enhance
this solution by enabling resynchronization of data between sites by using only the
changed data from the Metro Mirror target to the z/OS Global Mirror target after a
HyperSwap operation.
Copy Services Manager on the Hardware Management Console license
IBM Copy Services Manager facilitates the use and management of Copy Services
functions such as the remote mirror and copy functions (Metro Mirror and Global
Mirror) and the point-in-time function (FlashCopy). IBM Copy Services Manager is
available on the Hardware Management Console (HMC), which eliminates the
need to maintain a separate server for Copy Services functions.
The Copy Services Manager on Hardware Management Console (CSM on HMC)
license is available for the following license scopes: FB and ALL (both FB and
CKD).
The CSM on HMC license feature codes are ordered in increments up to a specific
capacity. For example, if you require 160 TB of capacity, order 10 of feature code
8451 (10 TB each up to 100 TB capacity), and 4 of feature code 8452 (15 TB each,
for an extra 60 TB).
The CSM on HMC license includes the following feature codes.
