Configuring IP partnerships

There are specific configuration requirements to partner two systems over native IP links connected directly or by Ethernet switches. The topics provided here describe the configuration settings that are needed for IP partnerships.

The system already supports remote copy over Fibre Channel. Remote copy over native IP provides a less expensive alternative to using Fibre Channel configurations.

Partnership over native IP brings with it changes to some fundamental assumptions in that no name server is in an Ethernet fabric to detect and discover remote copy ports. There are specific configuration settings such that the local and remote systems can discover each other's remote-copy capable IP addresses. TCP/IP sessions can then be set up across those IP addresses to establish a partnership.

Attention: The address for a system IP cannot be the same address that is used for the service IP. Using the same IP address causes an error.
