Sun Cluster 3.0-3.1 Hardware Administration Manual for Solaris OS


The Sun Cluster 3.0-3.1 Hardware Administration Manual for Solaris OS provides a variety of information about how to install and administer basic SunTM Cluster hardware components. Topics covered in this book include how to install and configure terminal concentrators, the cluster interconnect, public network hardware, campus clustering, and dynamic reconfiguration.

Use this manual with any version of Sun Cluster 3.0 or .31 software. Unless otherwise noted, procedures are the same for all Sun Cluster 3.0 and 3.1 versions.

Sun Cluster software runs on two platforms, SPARC and x86. The information in this document pertains to both platforms unless otherwise specified in a special chapter, section, note, bulleted item, figure, table, or example. Procedures are also the same unless otherwise noted for Sun Cluster 3.1 03/04 and later versions on both SPARC® and x86 based systems.

Note –

In this document, the term “x86” refers to the Intel 32-bit family of microprocessor chips and compatible microprocessor chips made by AMD.

In this document, references to Oracle Real Application Clusters also apply to Oracle Parallel Server unless otherwise stated.

See the Revision History for a list of changes to this manual.

This book does not include information about configuring servers in a Sun Cluster environment nor does it include specific storage device procedures.
