Getting Started
This section provides an overview for preparing and installing RAID Array 310 for HP-UX. Detailed
information is contained in Chapters 1 through 5.
Thank you for purchasing a StorageWorks RAID Array 310 Subsystem. The following is
an overview of the installation steps that are required.
NOTE
Installing the StorageWorks RAID Array 310 Subsystem
requires a general understanding of the following:
• HP 9000 Series 800 and 700 Computer Systems
• HP-UX 10.01, 10.10, or 10.20
• A fast, wide differential SCSI interconnection on the HP
machine
• Basic hardware installation procedures
Or, contact your service representative for installation
assistance.
Installation Roadmap
This section provides an overview/road map of the major steps required to install a RAID
Array 310 Subsystem. See the specified chapters for detailed procedures. (Depending
upon your specific configuration requirements, you may not need to perform all the tasks
listed.)
1. Perform the pre-installation steps listed below.
2. Unpack the RAID Array 310 Subsystem (Chapter 1)
3. Create a communications LUN (Chapter 2).
4. Install the SCSI Adapter in your HP system (if necessary)
5. Mount the software medium. The RAID Array 310 software and HP-UX support
files are provided on a CD-ROM.
6. Install the Command Console Agent (Chapter 4)
7. Plan your storagesets, which means “mapping out” your Stripeset, Mirrorset and/or
RAIDset configuration for the disks to be configured as your RAID Array. A useful
tool for this purpose is the blank configuration record forms provided in Appendix
A.
8. Create your storage configuration using either the Command Line Interpreter (CLI)
or the Command Console Client Graphical User Interface (Chapter 5).

Unpacking and Setting Up Your RAID Array 310
Subsystem Components
This chapter describes the site preparation and unpacking procedures for the RAID Array 310 Subsystem.
It also describes the procedure to recharge the controller write-back cache battery and making the CLI
interface connection between the subsystem and the host system or maintenance terminal.
1.1 Introduction
The installation of your RAID Array 310 subsystem is accomplished by performing the
following seven major steps:
• Unpacking and setting up the mechanical configuration (Chapter 1)
• Connecting ac power and recharging the controller cache battery (Chapter 1)
• Making the serial interface connection between the RAID Array 310 and the host
system or maintenance terminal (Chapter 1)
• Creating an initial RAID array controller configuration (Chapter 2)
• Preparing the HP9000 for use with the RAID Array Controller (Chapter 4)
1.2 Site Preparation
Before installing the subsystem, make sure that adequate space is available in front of the
enclosure for opening the front door (10 inches clearance) and around the enclosure for
adequate airflow. See Figure 1–1 for specific space requirements.

Figure 1–1 Minimum Installation Clearance Measurements
1.3 Unpacking the RAID Array 310
The shipping containers provide maximum protection for the subsystem and all
components. We recommend that you unpack the subsystem in the installation area.
NOTE
Before unpacking the equipment, inspect the shipping carton
for signs of external damage. Report any damage to the local
carrier and to your reseller.
Refer to Figure 1–2 and complete the following procedure to unpack the subsystem:
1. Orient the shipping container as shown.
2. Open the container to remove the subsystem and packing material.
3. Remove the top foam blocks.
4. Remove the door.
5. Remove the subsystem.
6. Replace all packing material in the shipping container and store it for future use.

Figure 1–2 Unpacking the RAID Array 310
1.4 Preparing the RAID Array 310 for Operation
Preparing the RAID Array 310 for operation involves the following procedures:
1. Mounting the base as described in Section 1.5.
2. Mounting the door.
3. Installing the disk Storage Building Blocks (SBB's).
4. Connecting the power, SCSI bus, and CLI serial cables.
5. Configuring the RAID Array 310.
6. Charging the controller cache battery.
7. Checking the subsystem for proper operation.

1–4 EK–SMRAB–IG. B01
1.5 Mounting the Base
Mount the stabilizing base to the subsystem as follows:
1. Place the subsystem on its top.
2. Align the base with the bottom of the subsystem as shown in Figure 1–3.
3. Install the four hex-head screws through the base into the subsystem and tighten the
screws using a 3/16 (5 mm) hex-head or flat-head screwdriver.
4. Set the subsystem on its base and continue the installation process.
Figure 1–3 Mounting the Base
1.6 Connecting the Subsystem Power Cords
The subsystem contains two identical power supplies which provide redundant power to
the RAID Array 310. Each supply is equipped with an ac power receptacle for
connection to a 125 or 250 Vac power source. The power supply automatically senses
and switches itself to accommodate either power source. Table 1–1 lists and describes
the Digital power cords available for the subsystem. Since these cords are country-
specific, ensure that your cords match those listed in Table 1–1 for your installation.
Obtain the correct power cords for your ac power source and connect them between the
ac receptacles on the power supplies (Figure 1–4) and the ac outlets (the power supply
automatically senses the voltage level and will work with either voltage). For optimal
fault tolerant operation, connect the supplies to independent ac sources.
