Manual: Cluster Server 4.1 Installation Guide |
Preparing to Use installvcsAs you run the installvcs utility, be prepared to answer prompts so that the installation can proceed smoothly and successfully. Use the following sections to guide you in preparing for the installation of VCS 4.1. If you want to install VCS packages on systems, but are not yet ready to configure the VCS cluster, refer to Using installvcs to Install Without Configuration. You can come back later with cluster information and perform the procedures in Using installvcs to Configure Without Installation. License KeyBe prepared to enter your VCS license key when prompted. See Obtaining License Keys for VCS. Choosing Optional PackagesThe optional packages included with VCS include:
I/O Fencing (Optional)If the I/O fencing option is selected, the installvcs utility installs the VCS I/O fencing driver, VRTSvxfen. After completing VCS installation, you must do the following to use the I/O fencing feature:
The VERITAS Cluster Server User's Guide describes I/O fencing in detail. I/O fencing protects the data on shared disks. When nodes in a cluster detect a change in cluster membership that could indicate a split brain condition, the fencing operation proceeds to determine which nodes are to retain access to the shared storage and which nodes are to be ejected from the cluster, thus preventing possible data corruption. VERITAS Security Services (Optional)VERITAS Security Services (VxSS) secures communication between cluster nodes and clients, including the Java and the Web consoles by using digital certificates for authentication and SSL to encrypt communication over the public network. For more information about VxSS, see the VERITAS Cluster Server User's Guide. If you decide to enable VxSS, you need to:
Required Cluster InformationBe prepared to provide the following information about the cluster and its systems:
Virtual IP Address for Cluster Manager (Web Console)You have the option to configure the Web-based Cluster Manager (Web Console). The Web Console is a graphical user interface that enables cluster monitoring and administration. If you choose this option, you must provide:
Information for Configuring SMTP NotificationYou have the option to configure SMTP email notification of VCS events by the VCS Notifier component. If you choose SMTP notification, be prepared to answer prompts for the following information:
The VERITAS Cluster Server User's Guide describes SMTP notification in detail; see the chapter on notification. Information for Configuring SNMP NotificationYou have the option to configure SNMP trap notification of VCS events by the VCS Notifier component. If you choose SNMP notification, be prepared to answer prompts for the following information:
If you choose the SMTP or SNMP notification option, the installer allows you to choose whether or not to use the same NIC as configured for the ClusterService group, which is the default. If you choose not to use the same networking information, you must specify appropriate values for the NIC, the virtual IP address, and the netmask when prompted. The VERITAS Cluster Server User's Guide describes SNMP notification in detail; see the chapter on notification. Information for the Global Cluster OptionYou have the option to configure the Global Cluster feature. The Global Cluster feature provides the ability to fail over applications between geographically distributed clusters when disaster occurs. The Global Cluster feature requires a license that you can add during the installation. If you choose the Global Cluster option, the installer allows you to choose whether or not to use the same NIC, virtual IP address, and netmask as are configured for the ClusterService group, which are the defaults. If you choose not to use the same networking information, you must specify appropriate values for the NIC, virtual IP address, and netmask when you are prompted. |
