VERITAS Cluster Server 6.x Workshop (Solaris / Linux)
Course: VERCS
Duration: 5 Days
Level: III
Course Summary
VERITAS Cluster Server (VCS) enables an organization to monitor systems and application services, and to restart services on a different system when hardware or software fails. The key to understanding VCS is to learn the various components and how they interact with one another. These include: clusters, resources and resource types, service groups, agents, and communications (GAB and LLT). This course covers the installation of VCS, configuration methods for service groups, configuring notification and troubleshooting problems, dependencies between service groups, startup and failover policies and managing network interface high availability.
Note that a shorter (3 day) version of this course is also available.
