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.

PREREQUISITES

• Background in Linux system and network administration including Logical Volume Manager (LVM) and/or Veritas Volume Manager (VxVM)

AUDIENCE

• Linux system and network administrators who currently, or soon will, develop, design, implement, and monitor Serviceguard (SG) clusters on Linux

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
• Using ‘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
