Course overview

This course teaches you how to use Serviceguard effectively to ensure the high availability of your systems. You will also learn how to configure and manage a Serviceguard cluster. This 5-day course is very lab-intensive, and is approximately 40 percent lecture and 60 percent lab.


Prerequisites

  • HP-UX System and Network Administration I (H3064S)
  • HP-UX System and Network Administration II (H3065S)
  • Hands On with Logical Volume Manager and MirrorDisk/UX (H6285S)
  • Experience with POSIX shell programming (H4322S)

Course objectives

  • Ensure high availability for your computer systems
  • Configure and maintain your Serviceguard cluster

Audience

  • HP-UX system administrators using or soon-to-be-using Serviceguard

Ways to save

Benefits to you

  • Effectively use Serviceguard to protect your mission critical applications from a wide variety of hardware and software failures.
  • Configure up to 16-nodes (systems, either PA-RISC or Integrity) in an enterprise cluster that delivers highly available application services to your LAN-attached clients.
  • Configure your Serviceguard cluster in such a way as to reduce application down-time to near zero.
  • Learn how to automate the detection of failures and restoration of application service, thus minimizing or eliminating your application downtime.
  • Reduce your planned downtime by using Serviceguard's rolling upgrade facility to change your cluster configuration while the cluster is running.

Next Steps

  • HP Serviceguard II: Disaster Tolerance, Continental Clusters, CFS, and Oracle RAC (U8601S).
  • HP StorageWorks XP 1: Configuration and Management (H6773S)
  • HP-UX Certified Systems Engineer CSE -HA exam (HP0-914). By passing the assessment examination you earn an HP Certified Advanced IT Professional certificate, and recognition for your skills.

If you require more assistance with Serviceguard, HP also offers Serviceguard implementation services (H4810AT). For more information about this service, contact your local HP services representative.
