# Netra High Availability Suite Foundation Services 2.1 6/03 Cluster Administration Guide # Preface This book describes how to maintain a cluster running the Netra™ High Availability (HA) Suite Foundation Services 2.1 6/03. ## Who Should Use This Book This book is for system administrators who are maintaining a cluster running the Foundation Services. This book helps administrators to do the following maintenance tasks: Map out a cluster network configuration Verify the configuration of a cluster or a node View and change a disk partition configuration Patch cluster software Add and replace cluster hardware ## Before You Read This Book To maintain a cluster that is running the Foundation Services you must have experience of working with a cluster environment. Knowledge of networking and system administration of the Solaris™ operating system is also required. ## How This Book Is Organized This book is divided into parts that contain related chapters. Part I, Using Cluster Administration Tools and Files introduces the suite of tools and configuration files you use to maintain and debug the cluster environment: Chapter 1, Using Cluster Administration Tools and Configuration Files describes how to use the Foundation Services tools and configuration files. It also describes the Solaris tools and configuration files that you can use. Chapter 2, Accessing and Maintaining Log Files explains how to configure and maintain your system log files. Part II, Verifying the Cluster Configuration contains procedures that verify whether a cluster is working correctly: Chapter 3, Determining Cluster Validity describes how to verify whether a group of nodes form a highly available cluster. This chapter also explains how to test whether a cluster is working correctly. Chapter 4, Examining the Cluster Networking Configuration shows how to examine the cluster network configuration and the external network configuration. Part III, Maintaining a Cluster contains procedures to use to maintain a cluster: Chapter 5, Using and Managing System Files explains how to manage differences between files that are not shared. In addition, this chapter describes how to configure the naming services. Chapter 6, Starting and Stopping Services, Nodes, and Clusters shows how to start a node without the Foundation Services. It also explains how to stop and restart a node or cluster. Chapter 7, Patching Software on the Cluster describes how to install a patch for the Foundation Services or for the Solaris operating system. Chapter 8, Modifying and Adding Disk Partitions describes how to resize a disk partition, how to add a new disk partition, and how to share a disk partition. Part IV, Adding and Replacing Hardware describes how to add nodes to a cluster and how to replace cluster hardware: Chapter 9, Adding a Node to a Cluster describes the options for adding a diskless node or dataless node to a cluster. Chapter 12, Replacing Ethernet Cards explains how to replace an Ethernet card on a peer node. Chapter 11, Replacing a CPU Board describes how to replace a board on a peer node. Chapter 13, Replacing a Disk shows how to replace a disk on a dataless node or the vice-master node.
