Planning a two-node IBM PowerHA SystemMirror cluster: Six must-know items
1. What is PowerHA SystemMirror for AIX?
Get an overview of the IBM PowerHA® SystemMirror high-availability (HA) solution, find out what it protects and learn about its product architecture.
2. Infrastructure planning and configuration
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.
3. Application planning and configuration
Learn how to use Smart Assists to simplify application planning and configuration. Manual configuration is also available.
4. Configure the application into PowerHA
Use either SMIT or the PowerHA SystemMirror IBM Systems Director plug-in to create the PowerHA cluster, nodes, networks, resources and resource groups.
5. Test the configured cluster
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.
6. What PowerHA course is right for my environment and administering my PowerHA cluster?
