Disaster Recovery using Veritas Replicator 6.0 and Global Cluster Option (Veritas Cluster Server 6.x) for UNIX


Course Description


Overview

The Disaster Recovery using Veritas Replicator 6.0 and Global Cluster Option (VCS 6.0) for UNIX course is designed for system administrators who implement, manage, and support disaster recovery environments that include VCS clusters across multiple sites with replication between sites. In this hands-on course, you learn the fundamentals of data replication and become proficient in planning, implementing, and managing the Veritas Replicator component of your disaster recovery strategy. You will be able to use Veritas Replicator in cluster environments together with Veritas Cluster Server for disaster recovery purposes.
Hands-On This course includes practical exercises, assessment items, and demonstrations that enable you to test your new skills and begin to transfer these skills into your working environment.
 

Audience

This course is for VCS administrators who are responsible for implementing and managing clusters across multiple sites using VVR as the data replication method.  

Prerequisites

You must have working knowledge of UNIX system administration and configuration. Completion of the Storage Foundation 6.0 and Veritas Cluster Server 6.0 Administration courses or equivalent experience on each product is required.
