How This Guide is Organized

Getting Acquainted with Clustering introduces you to the basics of clustering software, including failover detection and storage considerations.

VCS Technical Concepts explains the building blocks of VCS and how they interact with one another in a cluster environment, and introduces the core VCS processes.

Defining Cluster Topologies describes the various configuration types, or topologies, including replicated data clusters and global clusters.

Configuration Concepts describes the VCS configuration language, including attributes, definitions, clauses, and dependencies. This chapter also includes a list of key and reserved words, and an overview of basic configuration concepts, such as the contents of the main.cf and types.cf configuration files.

Introducing the VCS User Privilege Model introduces the VCS user categories and their associated privileges.

Administering the Cluster from the Command Line provides instructions on how to perform administrative tasks from the command line.

Administering the Cluster from Cluster Manager (Java Console) describes the VCS Java graphical user interface and provides instructions on how to perform administrative tasks.

Administering the Cluster from Cluster Manager (Web Console) describes the VCS Web-based graphical user interface and provides instructions on how to perform administrative tasks.

Configuring Application and NFS Service Groups describes the Application, and NFS wizards and provide instructions on how to use the wizards to create and modify the service groups.

VCS Communications, Membership, and I/O Fencing describes how the VCS engine, HAD, communicates with the various components of VCS. This chapter also explains how VCS behaves during failures in fenced and non-fenced environments.

Controlling VCS Behavior describes the default behavior of resource and service groups when they fail. This chapter also explains the latest load balancing mechanism and how VCS employs this functionality at the service group level.

The Role of Service Group Dependencies defines the role of service group dependencies and describes how to link service groups.

Notification explains how VCS uses SNMP and SMTP to notify administrators of important events, such as resource or system faults. This chapter also describes the notifier component, consisting of the VCS notifier process and the hanotify utility.

VCS Event Triggers describes how event triggers work and how they enable the administrator to take specific actions in response to particular events. This chapter also includes a description of each event trigger, including usage and location.

Connecting Clusters–Introducing the Global Cluster Option explains global clustering and presents key terms.

Administering Global Clusters from the Command Line provides instructions on how to perform administrative tasks on global clusters from the command line.

Administering Global Clusters from Cluster Manager (Java Console) provides instructions on how to perform administrative tasks on global clusters from Cluster Manager (Java Console).

Administering Global Clusters from Cluster Manager (Web Console) provides instructions on how to perform administrative tasks on global clusters from Cluster Manager (Web Console).

Setting Up Replicated Data Clusters describes how to set up a replicated data cluster configuration.

Setting Up Campus Clusters describes how to set up a campus cluster configuration.

Predicting VCS Behavior Using VCS Simulator introduces VCS Simulator and describes how to simulate cluster configurations.

VCS Performance Considerations describes the impact of VCS on system performance.

Troubleshooting and Recovery for VCS explains VCS unified logging and defines the message format. This chapter also describes how to troubleshoot common problems in VCS.

VCS User Privileges---Administration Matrices describes user privileges for VCS operations.

Cluster and System States describes the various cluster and system states and the order in which they transition from one state to another.

VCS Attributes lists the VCS attributes for each cluster object, including service groups, resources, resource types, systems, and clusters.

Administering VERITAS Web Server describes the VERITAS Web Server component VRTSweb and explains how to configure it. Cluster Manager (Web Console) uses VRTSweb.

Accessibility and VCS describes VCS accessibility features and compliance.
