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: Pre-Installation Steps
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.
