This manual is for the ASE or cluster administrator.
![[Prev. Section]](PREV.GIF){kind=small}
This manual consists of twelve chapters, three appendixes, and a glossary. A brief description of the contents follows:
| Chapter 1 | Introduces the concept of the available server
environment (ASE); compares and contrasts the use of ASEs in Production Server
clusters and Available Server configurations; explains the operation of the
daemons, drivers, and subsystems that comprise a cluster or ASE; and provides
a brief overview of the ASE manager utility (asemgr). |
| Chapter 2 | Describes how to configure and manage ASE and cluster membership. |
| Chapter 3 | Discusses how to configure and administer member and client networks in a Production Server cluster or Available Server configuration. |
| Chapter 4 | Explains how to prepare and set up highly available services, including discussions of the concepts fundamental to all types of service, such as Automatic Service Placement (ASP) policies, file systems and the Logical Storage Manager (LSM), and service action scripts. |
| Chapter 5 | Describes how to configure and start a Network File System (NFS) service. |
| Chapter 6 | Describes how to configure and start a disk service. |
| Chapter 7 | Describes how to configure and start a user-defined service. |
| Chapter 8 | Describes how to configure and start a distributed raw disk (DRD) service. |
| Chapter 9 | Describes how to configure and start a shared tape service. |
| Chapter 10 | Describes how to manage highly available services, including how to display service information, and delete, relocate, and temporarily stop services. It also describes the various mechanisms for modifying service, focusing on how to perform complex changes to a service's Advanced File System (AdvFS) and Logical Storage Manager (LSM) configuration. |
| Chapter 11 | Introduces the Cluster Monitor (cmon) and shows how to run the Cluster Monitor as a highly available
service. |
| Chapter 12 | Discusses how to investigate and resolve common TruCluster problems. |
| Appendix A | Describes alert messages that may be logged during the operation of a cluster. |
| Appendix B | Lists the kernel attributes provided by the cluster subsystems for Production Server clusters only. |
| Appendix C | Lists the configuration variables provided with TruCluster software. |
| Glossary | Describes the TruCluster software terms introduced in the documentation set. |
