Veritas InfoScale Availability 7.0 for Linux: Administration (HA0412)

Course Description

Duration 5 day

The Veritas InfoScale Availability 7.0 for Linux: Administration course is designed for the IT professional tasked with installing, configuring, and maintaining Veritas Cluster Server (VCS) clusters.

This five day, instructor-led, hands-on class covers how to use InfoScale Availability to manage applications in a high availability environment. After gaining the fundamental skills that are needed to manage a highly available application in a cluster, you can deploy InfoScale Availability in a lab environment to implement a sample cluster design.

Who should attend

This course is for Linux system administrators, system engineers, technical support personnel, network/SAN administrators, and systems integration/development staff, who will be installing, operating, or integrating InfoScale Availability.

Prerequisites

Knowledge of and hands-on experience with Linux systems administration

Course Objectives

By the completion of this course, you will be able to:

  • Describe how clustering is used to implement high availability in the data center environment.
  • Describe VCS and cluster communication mechanisms.
  • Create a cluster, and configure service groups and resources.
  • Implement and verify failover and failback capability. for application, storage, and network services.
  • Configure and optimize cluster behavior.
  • Protect data in a shared storage environment.
  • Describe I/O fencing operations, and its implementation.
  • Configure VCS to manage an Oracle database and other applications.
  • Configure a global cluster environment, including remote clusters, global heartbeats, and global service groups.
  • Configure notification and failover behavior in a global cluster.
