Host systems
A host system for Copy Services Manager is an IBM® z/OS® or AIX system that connects to storage systems to enable certain replication features for those systems.
A connection to a z/OS host system is required if you want to enable z/OS features, such as HyperSwap® and hardened freeze in Copy Services Manager sessions.

A connection to a z/OS host system is required if you want to enable z/OS features, such as HyperSwap and hardened freeze in Copy Services Manager sessions.
- A connection to an AIX® host system is required if you want to use the Open HyperSwap feature. This feature enables the automatic swap of input/output (I/O) to the volumes on a secondary site when a failure occurs when I/O is written to the primary site. For the swap to occur, the storage systems that contain the volumes must be attached to an AIX host and the AIX host must be connected to Copy Services Manager. The Open HyperSwap feature is optional for the Metro Mirror with Failover/Failback session type.
You can add both AIX and z/OS host connections in Copy Services Manager regardless of the operating system on which the application is installed. For example, you can add a connection to a z/OS host in a Copy Services Manager instance that is running on Windows, Linux®, or AIX.
