Preface

Solstice^{^(TM)} High Availability^{^(TM)} 1.0 (Solstice HA) is a software product that supports specific dual-server hardware configurations. It is compatible with the Solaris^{^(TM)} 2.4 software environment. When configured properly, the hardware and software together provide highly available data services. Solstice HA depends upon the mirroring and diskset capabilities and other functionality provided by Solstice DiskSuite^{^(TM)} 4.0, which is shipped with Solstice High Availability.

The SPARCcluster HA Server Software Planning and Installation Guide documents the procedures for setting up hardware and installing and configuring the software. This manual is intended to be used with other hardware and software manuals which are listed under "Related Documentation" on page xvii.

Who Should Use This Book

The information in this manual is for Sun representatives who are performing the initial installation of Solstice High Availability configurations. The instructions and discussions in this manual are complex and intended for a technically advanced audience.

The instructions in this manual and the SPARCcluster High Availability Software Planning and Installation Guide assume the reader has expertise with the Solstice DiskSuite product.

System administrators with at least six years of UNIX^{^(R)} system experience will find this book useful when learning to administer Solstice High Availability configurations. This manual should be used in conjunction with the SPARCcluster High Availability Software Administration Guide.

Note - Junior and less experienced system administrators should not attempt to install, configure, or administer Solstice HA configurations.
