About this Course

High Availability (HA) in an IBM i environment, known as PowerHA, is achieved with the implementation of an IBM i independent disk pool (Independent Auxiliary Storage Pool (IASP*) and IBM i 7.1 and 5771-HAS PowerHA for IBM i. After creating an IASP, data and applications are migrated from system disk space to the IASP. Once the IASPs have been created and used in a stand-alone environment, you will learn how to use IBM i clusters, geographic mirroring, and Copy Services to make the IASP highly available. Successfully implementing a continuously available environment requires knowledge of the application, data, and end-user requirements. Examine the considerations for a well-coordinated continuously available environment using IBM i clustering support. Learn about many of the concepts from a series of presentations and gain practical experience through hands-on lab exercises.

Audience Profile

This is an intermediate technical course for systems programmers and administrators who are considering high availability options for their IBM i environment.

At Course Completion

Upon completing this course, students will be able to:

  • Name the types of objects that can be placed in an IASP
  • Describe the methods used to access information in an IASP
  • Create an IASP
  • Use an IASP to support a variety of application functions
  • Manage a system with IASPs
  • Describe the different availability options using clusters and IASPs
  • Create a cluster
  • Make an IASP highly available with geographic mirroring
  • Practice switchover and failover operations
  • Explain the management considerations for systems in a cluster
  • Describe the use of Advanced Copy Services service offering with PowerHA


You should have an understanding of the IBM i concepts in areas such as system security, application implementation, system operations, work management, and communications.
