Using the installvcs Utility

The VCS installation utility, installvcs, is interactive. Using information you supply to its prompts, it installs VCS packages on each cluster system and configures VCS and its communication services. During the installation, you can select the optional: I/O fencing feature, security services, and VCS documentation packages. You can choose to configure the optional: Web-based Cluster Manager (Web Console), SNMP and SMTP notification features in the cluster, and the wide area Global Cluster feature. See Preparing to Use installvcs for highlights of the information for which installvcs prompts you.

Interacting with the installvcs Script

As you run the script, you are prompted to answer "yes or no" questions that are typically followed by a set of responses resembling[y, n, q, ?] (y). The response within parentheses is the default, which you may select by pressing Return. By entering the "?" character, you can get help to answer the prompt. By entering "q," you can quit the installation.

At some points during the installation, the installer prompts you to type information and expects your responses to be within a certain range or in a specific format. The installer provides examples. If you are prompted to enter an item from a list, enter your selection exactly as it is shown in the list.

When the installer prompts you to answer a series of questions related to a configuration activity, you can enter the "b" character to return to the first prompt in the series. When the installer displays a set of information items you have entered, you are prompted to confirm it. If you answer "n," the script lets you re-enter all of the information for the set. The installvcs utility does not configure GAB Disk heartbeat regions. This procedure must be done manually. Refer to Configuring Membership Heartbeat Regions on Disk (optional).
