Remote Copy target definitions

A target definition identifies the destination for data being replicated during Remote Copy operations. The secondary (or secondary-rev) system is the other system in the linked set of storage systems.

You specify target definitions during Remote Copy configuration.

For example, in a System1/System2 Remote Copy configuration, you specify target definitions as follows:

  • On System1, the target definition is System2.

  • On System2, the target definition is System1.

The name used for the target definition is not required to match the system name.

This relationship between target definitions and the linked storage systems is the same for all Remote Copy configurations.

Target definitions for a bidirectional Remote Copy configuration - example

The target definitions used by each Remote Copy group in the example are:

Volume group and location

Target definition/secondary system

For primary volume group groupX on System1

System2

For secondary volume group groupX.r11 on System2

System1

For primary volume group groupY on System2

System1

For secondary volume group groupY.r96 on System1

System2
