The Veritas InfoScale Availability 7.3 for UNIX/Linux: Advanced Administration II course is designed for the IT professional tasked with managing, configuring, and using clusters in an enterprise environment.

This class covers how to set up advanced service group and application configurations, manage system outages, and upgrade a cluster.

Note: This course does not teach basic clustering concepts and is a follow-on course from the Veritas InfoScale Availability 7.3 for UNIX/Linux: Administration course.

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

 Set up service group dependencies and virtual Business services.
 Use triggers to customize VCS behavior.
 Reconfigure cluster memberships.
 Control and customize application startup, failover, and shutdown.
 Manage system outages and upgrade clusters.

This course is for system administrators, architects, and technical support personnel who are responsible for implementing, managing, and supporting clusters in complex enterprise environments

You must have administrator-level experience with UNIX or Linux, TCP/IP networking, and clustering using Veritas Cluster Server.
