36 What’s Next?

Setting Up a SAN

Follow the instructions in this guide to set up a volume on a storage area network (SAN) using Xsan 2.

Is This the Right Guide for You?

To keep setup instructions simple, this guide assumes:

You are setting up a SAN for the rst time using new computers and RAID systems

right out of the box

You’ll let Xsan set up a SAN directory service on your metadata controllers

You’ll use the Mac OS X Server setup assistant to create SAN user accounts

You’ll choose a standard SAN volume type and let Xsan organize your storage pools

You’ll let the Xsan setup assistant congure your private metadata network settings

If you want to reuse existing computers while following this guide, you need to perform a clean installation of Mac OS X v10.5 or Mac OS X Server v10.5 or later on each of the computers before you begin.

If you want more control over the underlying organization of your SAN volumes or

directory services, you can nd more general instructions in the Xsan 2 Administrator’s Guide on the Xsan Install Disc and at www.apple.com/server/documentation.

If you already have a SAN that you want to upgrade to Xsan 2, you’ll nd instructions in

the Xsan 2 Migration Guide at www.apple.com/server/documentation.

Equipment You’ll Need

To set up a SAN using the instructions in this guide, you need:

RAID storage devices for SAN storage

Two computers running Mac OS X Server v10.5 to act as SAN metadata controllers

One or more SAN client computers running Mac OS X v10.5 or Mac OS X Server v10.5

An Intel or PowerPC G5 processor and at least 2 GB of RAM in each SAN computer

An additional 2 GB per SAN volume in each metadata controller that hosts more

than one SAN volume

An Apple Fibre Channel PCI, PCI-X, or PCI-E card installed in each SAN computer

A Fibre Channel switch and cables for all storage devices and computers

An Ethernet switch and cables for the private SAN metadata network

A second Ethernet switch and cables for public intranet and Internet access

An equipment rack for your RAID storage systems and Xserve computers

A list of qualied RAID systems and Fibre Channel switches is available on the Xsan

website at www.apple.com/xsan

6 Setting Up a SAN

What You Need to Know

You’ll need to provide the following information when you set up your SAN:

A static (xed) public IP address, subnet mask, router address, and DNS server

address for each computer on the SAN. You can enter this information manually or

congure a DHCP server to provide some or all of it. If you want the DHCP server

to provide IP addresses, it must always assign the same IP address to each SAN computer.

A single user name and password that will be used for the administrator account on

all SAN computers.

A unique user name and password for each user who will log in to a client computer.

An Xsan serial number for each computer on the SAN.

SAN Setup Instructions

Follow the instructions on the following pages to set up your SAN for the rst time.

Summary

1 Unpack and Install the SAN Hardware

2 Connect the SAN Networks

3 Set Up the Client Computers

4 Set Up the Standby Metadata Controller

5 Set Up the RAID Systems

6 Create a Metadata Array

7 Set Up the Primary Metadata Controller

8 Congure the SAN

9 Set Up a SAN Volume

Step 1: Unpack and Install the SAN Hardware

To install the components of your SAN, follow the instructions that come with each computer, RAID storage system, and switch. Don’t turn on any of the equipment until you are instructed to do so.

1 Unpack each computer that will be part of the SAN.

2 If you need to install Fibre Channel or Ethernet cards in any of the computers, follow

the instructions that come with the computer to install the card.

3 If you are using Xserve computers, follow the instructions that come with them to

install them in a rack.

4 Unpack the RAID systems that will provide your SAN storage and follow the

instructions that come with the systems to install them in a rack.

5 Unpack and install the Fibre Channel switch, following the instructions that come with

the switch.

6 Unpack and install the Ethernet switches for the SAN’s private metadata network and

public intranet or Internet connections.

Step 2: Connect the SAN Networks

Use Fibre Channel and Ethernet cables to connect the SAN computers and storage

devices to the Fibre Channel and Ethernet switches. Apple-qualied switches are ready to use right out of the box with no special conguration.

1 Turn on the Fibre Channel switch and connect each SAN computer to the switch using

one or two Fibre Channel cables.

2 Connect the Fibre Channel ports on each RAID storage unit to the Fibre Channel

switch. For details, see the instructions that come with the RAID system.

3 Turn on the Ethernet switches and connect the rst Ethernet port on each SAN

computer to the public Ethernet switch using an Ethernet cable.

4 Connect the second Ethernet port on each SAN computer to the private metadata

Ethernet switch using a second Ethernet cable.

5 Connect the Ethernet ports on each RAID storage system to the public Ethernet switch.

For details, see the instructions that come with the RAID storage system.

10 Setting Up a SAN

Step 3: Set Up the Client Computers

Now you’ll go to each client computer to set up an administrator account, congure network settings, and install the Xsan software. The procedure diers based on

whether the client has Mac OS X or Mac OS X Server installed. Use one of the next two procedures—“If a Client Has Mac OS X Installed” or “If a Client Has Mac OS X Server

Installed”—as appropriate on each client computer on the SAN. When you nish

setting up the client computers, they are ready to join the SAN and will be detected automatically during SAN setup.

After you nish setting up client computers, go on to Step 4, “Set Up the Standby

Controller Metadata.“

If a Client Has Mac OS X Installed

1 Turn on the client computer.

2 Follow the Mac setup assistant’s onscreen instructions to set up the computer. Pay

special attention to the information in the following panes:

Select Your Admin Account: If this pane appears, select “Create a local user account to administer this computer.”

Connect to Mac OS X Server: If this pane appears, deselect the “Use the following Mac OS X Server” option and click Continue.

Create Your Account: Enter the administrator account name and password that you plan to use on all SAN computers. To simplify SAN setup, use the same administrator name and password on all computers in the SAN.

3 When the Mac setup assistant nishes and the Finder appears, choose System

Preferences from the Apple () menu.
