RA7000 / ESA10000 High Availability Solution Kit for HP-UX 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 proced

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

1 Pre-Installation Steps This chapter addresses the preparation needed before installing and configuring the RA7000 / ESA10000 cluster hardware components. The pre-installation steps required to support a cluster are as follows: • Verify Cluster Requirements • Inventory the SCSI Connection Kit • Perform a System Backup Plan the Cluster Layout (e.g., the SCSI Bus Interconnect) • • Prepare the SCSI Host Adapters 1.1 Verify (RAID RA7000/ESA10000 for HP-UX) Cluster Requirements Please verify that t

RA7000 / ESA10000 High Availability Solution Kit for HP-UX NOTES 1. All of the host features that are supported by the platform kit are also supported in the RAID/HP cluster environment 2. The installation of a hub requires a 3.5” SSB slot available in your StorageWorks pedestal or shelf. 1.2 Inventory the RAID SCSI Connection Kit Three types of RAID SCSI Connection Kits exist. Each kit supports the connection of two host servers to a RAID subsystem via a single SCSI bus. To connect more than tw
