HP Serviceguard I (H6487)

In this course, you will learn how to effectively use Serviceguard to protect mission critical applications from a wide variety of hardware and software failures. You will spend 60 percent of class using HP servers in hands-on labs. This course has been updated to support HP-UX 11.31 and Serviceguard version A.11.20 but is still applicable to earlier versions of the product.

What You'll Learn

  • Configure a volume group or disk group that can be used on multiple systems and a basic package to run in a Serviceguard environment
  • Configure and maintain a Serviceguard cluster
  • Configure and implement an application monitor
  • Replace a failed LVM lock disk
  • Change the cluster configuration and add/delete a package to a running cluster
  • Set up a Serviceguard package using the NFS toolkit and Oracle toolkit
  • Configure a highly available network using redundant hubs, routers, and networks
  • Perform a rolling upgrade
  • Use Serviceguard Manager to manage a Serviceguard cluster
  • Perform troubleshooting activities to resolve Serviceguard configuration problems
  • Protect your mission critical applications against a wide variety of hardware and software failures through effective use of Serviceguard
  • Deliver highly available application services to your LAN-attached clients by configuring up to 16-nodes in an enterprise cluster
  • Reduce your application downtime to near zero by learning how to configure your Serviceguard cluster and using Serviceguard's rolling upgrade facility
  • Minimize, and in some instances eliminate, your application downtime by automating the detection of failures and restoration of application service
