20 Preparing to install and configure VCSAbout VCS 5.0 featuresAbout VCS 5.0 featuresTo configure the optional features of the VCS components, make sure to installall packages when the installation program prompts you. Review the descriptionof the optional features and decide the features that you want to configure withVCS:■■■■■Symantec Product Authentication ServiceSMTP email notification for VCS eventsSNMP trap notification for VCS eventsGlobal clusters using VCSI/O fencingSymantec Product Authentication ServiceSymantec Product Authentication Service secures communication betweencluster nodes and clients, including the Java console, by using digital certificatesfor authentication and SSL to encrypt communication over the public network.For more information about the Authentication Service, see the Veritas ClusterServer User’s Guide.To configure the cluster in secure mode, VCS requires you to configure a systemin your enterprise as root broker and all nodes in the cluster as authenticationbrokers.■■Root brokerA root broker serves as the main registration and certification authority; ithas a self-signed certificate and can authenticate other brokers. The rootbroker is only used during initial creation of an authentication broker.Authentication brokersAuthentication brokers serve as intermediate registration and certificationauthorities. Authentication brokers have certificates that are signed by theroot. Each node in VCS serves as an authentication broker.You can set up Authentication Service for the cluster during the installation orafter installation. Refer to the Veritas Cluster Server User’s Guide to configurethe cluster in secure mode after the installation and configuration process.See “Configuring the cluster in secure mode” on page 54.Figure 2-4 depicts the flow of configuring VCS in secure mode.
