Veritas Cluster Server 6.x for Unix: Advanced Administration
This class covers how to set up advanced network and data protection configurations, customize VCS behavior using triggers and service group dependencies, and manage system outages. Students also learn how to control VCS behavior for service group startup and failover. In addition, students learn how to reconfigure cluster membership, upgrade a cluster, and configure campus clusters.
Hands-On This course includes practical hands-on exercises that enable you to test your new skills and begin to use those skills in a working environment.
AudienceThis course is for system administrators, architects, and technical support personnel who are responsible for implementing, managing, and supporting clusters in complex enterprise environments.
PrerequisitesYou must have administrator-level experience with UNIX or Linux, TCP/IP networking, and clustering using Veritas Cluster Server.
