Preface

The Sun StorEdge A3500/A3500FC Hardware Configuration Guide provides configuration instructions for the Sun StorEdge™ A3500/A3500FC systems. These instructions are designed for an experienced system administrator.

How This Book Is Organized

Chapter 1 describes configurations for one or two small computer system interface (SCSI) StorEdge A3500 controller modules connected to one or more hosts. It also contains information about connecting power to a Sun Ultra™ host system.

Chapter 2 describes configurations for one or two Fibre Channel-Arbitrated Loop (FC-AL) StorEdge A3500FC controller modules connected to one or more hosts.

Chapter 3 explains how to set up the configurations supported by Sun. It also includes information about StorEdge D1000 disk array settings and cables and connections for each configuration.

Appendix A contains specifications for the StorEdge A3500/A3500FC systems.

Using UNIX Commands

This document does not contain information on basic UNIX®commands and procedures such as shutting down the system, booting the system, and configuring devices.

CHAPTER

SCSI Host Connections

This chapter describes configurations for one or two small computer system interface (SCSI) Sun StorEdge A3500 controller modules connected to one or more hosts. It also contains information about connecting power to a Sun Ultra™ host system.

The topics covered in this chapter are:

■ Configuration Guidelines—page 1-2

■ Supported SCSI Host Configurations—page 1-3

■ Single Host Connected to One Controller Module—page 1-3

■ Two Controller Modules Daisy-Chained to One Host—page 1-4

■ Independent Controller Module Connected to Two Hosts—page 1-5

■ Multi-Host—page 1-6

■ Ultra 2 Host System Power Connection Requirement—page 1-7

Note – The RAID Manager 6.22 software does not support Ultra 2 host systems.

1-1

1.1 Configuration Guidelines

Use the following guidelines to install and cable or reconfigure your StorEdge A3500 system.

■ The part number for the 12 meter SCSI host cable is 530-1886-xx.

■ Do not exceed a SCSI bus length of 25 meters (82 feet).

■ Make sure that the last StorEdge A3500 controller module in any daisy chain has

a total of two terminators—one in each SCSI OUT port.

■ If you are adding a controller module to an already existing configuration, halt all

activity on the SCSI bus before removing any SCSI cables.

■ Once you finish cabling the devices and powering on, reboot the system by

typing boot -r at the ok prompt before beginning any SCSI bus activity.

■ Perform a system check to make sure that SCSI connections are secure. Look for

fault LEDs on the hardware or error messages in the RAID Manager GUI.

Note – Refer to your server and rack documentation for instructions on grounding

the StorEdge A3500 expansion cabinet.

1.2 Supported SCSI Host Configurations

The illustrations in this section show the SCSI cable connections for the configurations that are supported by Sun.

■ Single Host Connected to One Controller Module

■ Two Controller Modules Daisy-Chained to One Host

■ Independent Controller Module Connected to Two Hosts

■ Multi-Host

For more information regarding the two-node multi-host configuration, such as instructions for setting host SCSI IDs, refer to the Sun™ Cluster documentation that is shipped with the host system.

For information about StorEdge A3500/A3500FC support for multi-host configurations, refer to “Frequently Asked Questions” (FAQ) in the Sun StorEdge

RAID Manager 6.1.1 Release Notes (805-3656-xx) and in the Sun StorEdge RAID Manager 6.22 Release Notes (805-7758-xx) and to the Sun StorEdge RAID Manager User’s Guide.

1.3 Ultra 2 Host System Power Connection Requirement

You can connect a controller module to an Ultra 2 host system; however, you must connect the power cord of the Ultra 2 host to one of the AC power sequencers in the expansion cabinet that contains the controller module.

Note – The RAID Manager 6.22 software does not support Ultra 2 host systems.

You need to order one of the following power cords depending on the type of power sequencer in the expansion cabinet (

■ Ultra Enterprise™ expansion cabinet and StorEdge expansion cabinet—

part number 530-2197

■ 1422 mm/56-inch Data Center expansion cabinet—part number 180-1189 (United

States) or 180-1190 NEMA (European)

Caution – Failure to connect the power cord correctly as described here may cause

excessive ground current that could damage the system.

Connect Ultra 2 power cord here

1422 mm/56-inch data center expansioncabinet power sequencer

To connect the power cord:

1. Gain access to the AC power sequencers.

See the documentation that came with the expansion cabinet.

2. Route the power cable from the Ultra 2 host under the expansion cabinet frame on the same side as the power sequencer.

3. Connect the power cord from the Ultra 2 host into the top power connector of either power sequencer (

FIGURE 1-5).

The power connectors are located on the other side of the power sequencer from the main switch.

4. Reassemble the expansion cabinet.

See the documentation that you received with the expansion cabinet.
