RA7000 / ESA10000 High Availability Solution Kit for
Defining a “Clustered Host Server”
For the host servers to be considered part of “the cluster” (e.g., share the RAID subsystem(s) and possess I/O failover capabilities), each server must be configured with MC/ServiceGuard cluster software, (including a “package” to failover the RAID CC agent), and the SCSI pass through device drivers that enable the SWCC agent to communicate with the RAID subsystem(s).
This guide provides a master procedural roadmap to establish a “basic” cluster of shared RAID storage, focusing on cluster hardware and software configuration tasks. It begins with a new, boxed RAID subsystem and two HP host servers. Procedures for expanding a cluster are also discussed.
Audience
This guide is intended for experienced administrators and system integrators of HP host server and StorageWorks RA7000 / ESA10000 storage subsystem equipment. Setting up a cluster requires a general understanding of HP server networks, RAID storage concepts, HP MC/ServiceGuard cluster software and SCSI hardware configurations. Or, contact your service representative for installation assistance.
Document Structure
This guide contains the following chapters:
Getting Started
This section provides a roadmap to serve as the master procedural guide for establishing a cluster.
Chapter 1:
This chapter addresses the preparation needed before installing the hardware components of the RAID subsystem cluster. It provides a guide to your options in planning the cluster layout (e.g., the shared RAID subsystem, host servers and, if applicable, the SCSI hub), through the SCSI bus. This chapter also describes how to prepare the two SCSI host adapter boards for a cluster environment.
