Preface

The Sun Cluster 3.1 - 3.2 With StorageTek 2540 RAID Arrays Manual for Solaris OS provides procedures that are specific to a Sun StorageTek^TM 2540 array that is placed in a Sun^TM Cluster environment.

Use this manual with any version of Sun Cluster 3.1 or 3.2 software on SPARC® based clusters and on any supported version of Sun Cluster 3.1 or 3.2 software on x86 based clusters. Use this manual with any version of Sun Cluster 3.1 or 3.2 software. Unless otherwise noted, procedures are the same for all Sun Cluster 3.1 or 3.2 versions.

This book assumes that you are performing one or more of the following tasks:

• You want to replace an array component to prevent a failure.

• You want to replace an array component because you have an existing failure.

• You want to add (to an established cluster) or install (to a new cluster) a storage array.

Note –

This Sun Cluster release supports systems that use the SPARC and x86 families of processor architectures: UltraSPARC, SPARC64, and AMD64. In this document, the label x86 refers to systems that use the AMD64 family of processor architectures.

The information in this document pertains to both platforms unless otherwise specified in a special chapter, section, note, bulleted item, figure, table, or example.
