Veritas Cluster Server service groups are virtual containers that manage groups of resources required to run a managed application. You can create multiple service groups on a single node and they can function independently of each other. Moreover, you can also assign dependencies among the service groups depending on the complexity of your managed application.
For more information, see About service groups.
VCS supports three types of service groups:
For more information on failover service groups, parallel service groups, and hybrid service groups, see:
For more information on campus clusters, see Setting up campus clusters.
VCS components are configured using attributes. Attributes contain data about the cluster, systems, service groups, resources, resource types, agent, and heartbeats if you use global clusters. Moreover, the value assigned to the parallel attribute determines whether the service group is failover, parallel, or hybrid.
Administering service groups
You can administer service groups using the Java console, VCS command line interface, or Veritas Operations Manager (VOM). Symantec recommends using VOM to manage Cluster Server environments. The following are the links to the topics addressing administration of service groups using either method.
