HP RA7000 manual Cabling the RAID Subsystem Cluster Components

About This Guide

Chapter 2: Cabling the RAID Subsystem Cluster Components

This chapter describes the procedures for cabling a RAID subsystem to two HP host servers based on the cluster (SCSI) layout option selected in Chapter 1 of this guide. (Reference Appendix A if clustering more than two hosts or more than one RAID subsystem). It provides detailed illustrations of the cabling and termination required to support HD68-pin SCSI host adapter compatibility, and the use of a SCSI hub.

Chapter 3: Software Setup Requirements for a Cluster

This chapter summarizes and describes, in sequence, each of the software setups required to establish a cluster environment between multiple HP-UX host servers and a shared RAID storage subsystem. It explains how to access, invoke and interact with the SWCC Failover Transition Module Installation Script, which automatically configures the cluster for the seamless failover of the StorageWorks Command Console RAID Manager agent in the event of a server shutdown.

Appendix A: Cabling and Termination Required to Expand a Cluster

An expanded cluster is one in which more than two host servers are connected to a RAID subsystem on the same SCSI bus, or where a second RAID subsystem is added to the cluster on a separate SCSI bus. Appendix A provides the hardware cabling and termination, and highlights the software configurations required to expand a cluster.

Appendix B: De-Installing the SWCC Failover Transition Module

This appendix describes how to reverse the installation of the StorageWorks Command Console Failover Transition Module (agent) within a cluster.
