Get an overview of the IBM PowerHA® SystemMirror high-availability (HA) solution, find out what it protects and learn about its product architecture.
To plan and implement a two-node PowerHA cluster, you should determine what version of PowerHA you will implement, what version of the IBM AIX® operating system will be required, how you will handle Ethernet network and storage redundancy, and lastly, how many PowerHA nodes will be in the cluster.
Learn how to use Smart Assists to simplify application planning and configuration. Manual configuration is also available.
Use either SMIT or the PowerHA SystemMirror IBM Systems Director plug-in to create the PowerHA cluster, nodes, networks, resources and resource groups.
Learn about various test plans and simulations to help you determine if PowerHA is configured and working correctly. After you have created the cluster, run the test plan, documenting behaviors and resolving problems.
For more detailed information and lab exercises, consider IBM Training. A PowerHA SystemMirror for AIX cheat sheet is also included.
