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
Skills Gained
- Describe industry-standard replication technology concepts and components.
- Describe concepts and components specific to Veritas Replicator.
- Develop a plan and implement Veritas Replicator.
- Initialize, synchronize, and replicate sample data.
- Perform a takeover, migration, and failback.
- Use a bunker site for disaster recovery.
- Perform off-host processing at the secondary replication site.
- Troubleshoot a replicated data environment.
- Configure a global cluster using the VCS Global Cluster Option.
- Manage a global cluster environment, including remote clusters, global heartbeats, and global service groups.
- Configure notification and failover behavior in a global cluster.
- Describe how VCS supports replication.
- Implement and manage replication in a global cluster.
- Perform off-host processing under VCS control.
- Implement a replicated data cluster.
Who Can Benefit
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
