1 Introduction

Overview

HP StoreOnce Backup Systems are a family disk-based storage appliance for backing up host network servers or PCs to target devices on the appliance. These devices are configured as either Network-Attached Storage (NAS) or Virtual Tape Library (VTL) targets for backup applications.

The total number of “devices” depends upon the StoreOnce appliance ranging from the low end HP D2D4000 Series Backup Systems that support the creation of a maximum of 16 devices to the enterprise class B6200 Series that support the creation of 96 devices. These devices may be all VTL, all NAS or any combination of NAS and VTL devices.

For specific details of the VTL and NAS device options available, please refer to the User Guide for your Product.

NAS targets for backup applications

Support for both CIFS and NFS protocols means that NAS target devices may be created as backup targets for both Windows and UNIX/Linux hosts, and may be used with most backup applications that support backup to disk. NAS targets on an HP StoreOnce Backup System provide network file share access that is optimized for backup to disk. They should not be used for general purpose file storage.

Virtual Tape Library targets for backup applications

The backup target appears to the host as an Ultrium Tape Library and requires a backup application that supports backup to tape. Tape Library emulation type is selected during initial configuration and this determines the number of cartridge slots and embedded tape drives that may be configured for the device. Virtual Tape Libraries provide considerable flexibility for a variety of backup rotation schemes.

For specific details of the VTL device options available, please refer to the User Guide for your Product.

Hardware installation

Please refer to the installation instructions provided with your product for detailed instructions on installing the HP StoreOnce Backup System and optional tape drive.

Software requirements

1. Refer to www.hp.com/go/connect or http://www.hp.com/go/ebs to find out which versions of UNIX and Linux are supported and which backup applications are supported.

2. Make sure that your operating system is patched with the latest service packs.

3. Upgrade your backup application to the latest version.

Configuration stages

Configuration requirements are specific to each HP StoreOnce Backup System. This guide provides details for all products so please cross check the information provided to ensure it is relevant for your product.

In general, there are two stages to configuration:

• Assign IP addresses to the appliance network settings

• Create a base configuration to get started

This guide describes how to perform these two stages.

Overview 5

2 Discovery

Overview

The HP StoreOnce Backup System must be assigned an IP address before an iSCSI connection or access to the Web Management Interface can be made.

If your product has been installed by HP Engineers, this configuration will have been carried out. Go to Chapter 3.

If your product is a customer self-install product, use the remainder of this chapter to perform the required configuration:

• If the network has a DHCP server, the HP StoreOnce Backup System will be configured

automatically with an IP address

• If no DHCP server is available, the HP StoreOnce Backup System must be configured manually

using the HP Discovery tool, provided on the HP StoreOnce CD-ROM supplied with your product

Using DHCP to discover the HP StoreOnce Backup System

The IP address and other network settings are assigned automatically when you connect the HP StoreOnce Backup System to the network. You only need to know the serial number of the HP StoreOnce Backup System to complete the installation and create a library configuration. The serial number can be found on a label on the top of the unit.

In the web browser type in: D2D-<serial number> If you cannot connect to the HP StoreOnce Backup System using the Web Management interface:

• Check that you are using a supported web browser and that Active Scripting or JavaScript is

enabled. See the HP StoreOnce Backup System User Guide for more information about recommended web browser settings.

• Check that the network light is on, on the front of the HP StoreOnce Backup System as this

indicates an IP address has been configured.

• Try connecting to the HP StoreOnce Backup System using the DHCP assigned IP address

instead.

Using the HP Discovery tool

The HP Discovery tool is a java application for configuring HP StoreOnce Backup Systems. The tool can be run from HP StorageWorks CD-ROM by selecting HPdiscovery in the UNIX folder or by launching it from a console as follows:

localhost:~ $ cd /media/cdrom/UNIX/ localhost:~ $ ./HPdiscovery

NOTE: Java must be installed on the system for the HP Discovery tool to work. Java can be

installed using the package manager or by visiting http://java.sun.com

When the HP Discovery tool is run it will find any HP StoreOnce Backup Systems on the local network and list them by name. The name displayed by the HP Discovery tool should match the label on the top of the HP StoreOnce Backup System.

6 Discovery

NOTE: If no HP StoreOnce Backup Systems are discovered, ensure that UDP port 8106 is open

in any firewalls that are running.

To identify the required device

If you have multiple HP StoreOnce Backup Systems on the network you can use the Beacon button to help identify the unit that you wish to configure. Select a device in the list and click Beacon. The lights on the front of the selected HP StoreOnce Backup System will flash.

To configure the network settings of a device

1. Select the device in the list and click Configure.

Using the HP Discovery tool 7

2. Enter the network details and click Configure to send the details to the HP StoreOnce Backup

System. The list of available HP StoreOnce Backup System on the network will be displayed again, this time with the updated network settings shown.

3. Make a note of the IP address of the HP StoreOnce Backup System because it will be required during iSCSI configuration.

8 Discovery

3 Linux (x86, x64 and IA64)

Overview

This chapter describes how to configure the HP StoreOnce Backup System for use with the following Linux operating systems:

• SuSE Linux Enterprise Server 9 (x86, x64 and IA64)

• SuSE Linux Enterprise Server 10 (x86, x64 and IA64)

• RedHat Advanced Server 4 (x86, x64 and IA64)

• RedHat Advanced Server 5 (x86, x64 and IA64)

NOTE: HP StoreOnce Backup Systems with iSCSI interfaces are only supported with SLES 10

SP1 and RedHat 5 or greater.

Configuring the HP StoreOnce Backup System for iSCSI

If your product supports iSCSI use the information in this section to configure it. If your product does not support iSCSI, go to Configuring the HP Backup System for Fibre

Channel (page 11).

How to install the Open-iSCSI module

SLES 10

1. Open the Software Management tool from within YaST Control Center.

2. Select and install the open-iscsi module.

RedHat 5

1. Open the Package Manager tool.

2. Select and install the iscsi-initiator-utils package.

How to configure the Open-iSCSI module using the D2Dsetup script

Use the D2Dsetup script to configure the Open-iSCSI module automatically. You must provide the IP address as a parameter to the script.

localhost:~ $ D2Dsetup <IP_address>

If you wish to configure CHAP authentication, you should also provide the user name and password for the initiator and the target, if required.

localhost:~ $ D2Dsetup <Initiator_CHAP_Username> <Initiator_CHAP_Password> <Target_CHAP_Username> <Target_CHAP_Password> <IP_address>

The response from the HP StoreOnce Backup System will be similar to the following:

How to configure the Open-iSCSI module manually using the command line

The command line tool for configuring the Open-iSCSI package is iscsiadm. Detailed instructions for iscsiadm can be found in the iscsiadm(8) man documents. The following instructions guide the user through the following steps required to connect a Linux host to an HP StoreOnce Backup System.

• Discover iSCSI target devices on the HP StoreOnce Backup System

• Configure CHAP authentication

• Configure automatic iSCSI logins

• Verify the HP StoreOnce Backup System is connected

1. To discover available iSCSI target devices on an HP StoreOnce Backup System type the following, where x.x.x.x is the IP address of the HP StoreOnce Backup System:

localhost:~ $ iscsiadm --mode discovery --type sendtargets --portal x.x.x.x | grep x.x.x.x

The response from the HP StoreOnce Backup System will be two iSCSI Qualified Names (IQN) for each available iSCSI target. For example:

[7db5cb] x.x.x.x:3260,1 iqn.1986-

03.com.hp:storage.d2d.cr204c84d5.500110aa76f68fcb.library1.robotics [ebf06d] x.x.x.x:3260,1 iqn.1986-

03.com.hp:storage.d2d.cr204c84d5.500110a05ed5497b.library1.drive1

In the following configuration the parameter <iqn...> should be replaced with the IQN value discovered in this step. Each command will need to be repeated for each IQN discovered.

NOTE: Note: If iscsiadm does not return a list of iSCSI targets, ensure that port 3260 is

open in any running firewalls.

2. To optionally configure CHAP authentication you should update the iSCSI Authentication details in the web management GUI, as shown below.

Once the HP StoreOnce Backup System has been modified, the operating system should be modified as follows for each available target discovered in step 1:

NOTE: In the following commands, items in parentheses are user-defined strings. Substitute

the appropriate information for <iqn...>, <chap_password> and <chap_username>.
