HP ServiceGuard on Linux (H4C21S)

Course overview

This course is designed for experienced Linux system and network administrators implementing HP Serviceguard A.12.00. Topics include the basic requirements of a highly available system and progress through to the configuration of a Serviceguard cluster/packages, culminating in using both NFS and Oracle 11gR2 toolkit packages along with using the cluster simulator and analytics utilities. The course is 50 percent lecture and 50 percent hands-on labs using RHEL 6.4.

Audience
  • Linux system and network administrators who currently, or soon will, develop, design, implement, and monitor Serviceguard (SG) clusters on Linux
Prerequisites
  • Background in Linux system and network administration including Logical Volume Manager (LVM) and/or Veritas Volume Manager (VxVM)
Course objectives

At the conclusion of this course you should be able to:

  • Configure, implement, and manage an HP SG cluster and packages
  • Install HP Serviceguard A.12.00 and Serviceguard Manager
  • Use ‘cmeasyinstall’
  • Utilize basic troubleshooting techniques
  • Install and configure NFS and Oracle packages using the toolkits
  • Use Live Application Detach and 'rolling upgrade'
  • Configure generic resources
  • Use the SG simulator and SG cluster analytics
Benefits to you
  • Protect mission critical applications against a variety of hardware and software failures through effective use of Serviceguard on Linux
  • Reduce application downtime by learning how to configure Serviceguard cluster and using Serviceguard's rolling upgrade facility
  • Minimize, and in some instances eliminate, your application downtime by learning how to automate the detection of failures and restoration of application service
