To function as a cluster member, the following software must be installed:
Solaris operating environment
Sun Cluster software
Data service application
Volume management (Solaris Volume ManagerTM or VERITAS Volume Manager)
An exception is a configuration that uses hardware redundant array of independent disks (RAID). This configuration may not require a software volume manager such as Solaris Volume Manager or VERITAS Volume Manager.
See the Sun Cluster 3.1 System Administration Guide for information on how to install the Solaris operating environment, Sun Cluster, and volume management software.
See the Sun Cluster 3.1 Data Service Collection for information on how to install and configure data services.
See Chapter 3, Key Concepts for Administration and Application Development for conceptual information on the preceding software components.
The following figure provides a high-level view of the software components that work together to create the Sun Cluster software environment.
See Chapter 4, Frequently Asked Questions for questions and answers about cluster members.
