Introduction
The HP StoreOnce Backup system is a disk-based storage appliance for backing up network media
servers or PCs to target devices on the appliance. These devices are configured as either
Network-Attached Storage (NAS), Catalyst Stores or Virtual Tape Library (VTL) targets for backup
applications.
This guide describes how to install and carry out the initial configuration of your HP StoreOnce
Backup system. The following documents are also available at http://www.hp.com/support/
manuals:
•HP StoreOnce Installation posters: Installation posters are available for each product family
(2620, 42xx and 44xx) and describe how to quickly install the product by connection LAN
Port 1 to a 1GbE network.
•HP StoreOnce Backup system User Guide: This guide contains detailed information on using
the Web Management Interface. It also contains troubleshooting information, including details
on replacing failed or failing hard disks.
•HP StoreOnce Backup system CLI Reference Guide: This is the full reference guide for the
StoreOnce Command Line Interface, CLI.
•HP StoreOnce Backup system Linux and UNIX Configuration Guide: This guide contains
detailed information about configuring HP StoreOnce Backup systems with supported Linux
and UNIX operating systems.
•StoreOnce Best Practices for VTL, NAS and Replication implementations: This white paper
advises how to plan the workload being placed on the HP StoreOnce Backup system in order
to optimize performance and minimize the impact of deduplication, replication and
housekeeping operations competing for resources. It is regularly updated.
•HP StoreOnce Backup system Concepts Guide: If you are new to the HP StoreOnce Backup
system, it is a good idea to read this guide before you configure your system. It describes the
StoreOnce technology.
HP StoreOnce G3 models
The following products belong to the HP StoreOnce G3 Backup system family; they are also referred
to as single-node StoreOnce models, in comparison to the HP StoreOnce B6000 Backup system
which is a multi-node StoreOnce product. (This node distinction is important when configuring
replication and Catalyst copy jobs and understanding target and source IP addresses.)
•BB852A: HP StoreOnce 2620 iSCSI Backup system
•BB853A: HP StoreOnce 4210 iSCSI Backup system
•BB854A: HP StoreOnce 4210 FC Backup system
•BB855A: HP StoreOnce 4220 Backup system
Introduction 5

•BB856A: HP StoreOnce 4420 Backup system
•BB857A: HP StoreOnce 4430 Backup system
NOTE: The HP StoreOnce 4210 iSCSI/FC product is fitted with 1TB disks (the same as the HP
StoreOnce 4220 Backup system), however, the configured available disk capacity of the system
is approximately 50% of this available disk capacity. The system cannot use the whole capacity
of the fitted disks because the product is not fitted with the required memory or processor to make
use of the additional capacity.
Converting from G2 models
HP is offering existing StoreOnce D2D Single Node G2 customers the ability to convert their
appliances to the next generation of StoreOnce software for free. HP StoreOnce G3 software offers
several significant features, the most important being the introduction of HP StoreOnce Catalyst
devices that allow low and high bandwidth backups and backup application controlled, off-site
copy between StoreOnce appliances for those customers using HP DataProtector or Symantec
OST.
WARNING! HP StoreOnce G3 software is significantly different to G2 and, as such, the conversion
process is data destructive.It is recommended that ONLY customers who need to take advantage
of the new features convert their products. Contact HP Support for further details. The conversion
process is not described in this guide.
Software and hardware requirements
Refer to http://www.hp.com/go/ebs for the latest connectivity and compatibility information.
Supported Ethernet configurations
The HP StoreOnce Backup system supports a wide range of network configurations. The following
list summarizes configuration details. See Network configuration (page 17) for more details about
configuring the network.
•An Ethernet connection is required for backing up to NAS shares, Catalyst stores or iSCSI VTL
devices, and replication activities, and for all StoreOnce management tasks via the GUI or
CLI.
•The HP StoreOnce Backup system supports IPv4 only.
•DHCP and static IP addressing are supported.
•All StoreOnce Backup systems have two 1GbE ethernet ports. HP StoreOnce 4420/4430
Backup systems have two additional 10GbE ports. Mode 6 bonding is supported on pairs of
1GbE and 10GbE ports.
•Networking parameters are contained within a network configuration file. For ease of
installation, a default configuration file is supplied with the StoreOnce Backup system. As long
as LAN port 1 of the appliance is connected to a DHCP–enabled 1GbE network switch, the
HP StoreOnce Backup system will be immediately active on the network after installation.
The user then has the option of continuing to use the default configuration file or creating and
activating an additional configuration file that is tailored to their exact networking requirements.
NOTE: 100 Base-T Ethernet will limit performance.
•Users who do not have a DHCP-enabled 1GbE network must create and activate a network
configuration file before their system can become active on the network. This network
configuration file may use any available Ethernet port, but one must always be connected,
even if you are only using the FC ports to back up and restore data to the HP StoreOnce
6 Before you start

Backup system. This is because the network is used to access the StoreOnce Management
Console remotely; it is also used for replication.
Supported Fibre Channel connections
NOTE: Fibre Channel is not supported on the HP StoreOnce 2620 or the HP StoreOnce 4210
iSCSI Backup system.
•When connecting to a Fibre Channel network (for backing up to FC VTL devices), the HP
StoreOnce Backup system is supplied with the correct FC card pre-installed. Cables are not
supplied.
•The HP StoreOnce Backup system supports both switched fabric and direct attach private loop
topologies. Direct attach point-point topologies are not supported.
A switched fabric topology utilizes one or more fabric switches to provide a flexible
configuration between several Fibre Channel hosts and Fibre Channel targets such as HP
StoreOnce Backup systems.
•Switched fabric configurations are implemented with Fibre Channel switches. Switches may
be cascaded or meshed together to form larger fabrics.
•The preferred topology for the HP StoreOnce Backup system is switched fabric using NPIV
(N_Port ID Virtualisation).
NOTE: Please refer to http://www.hp.com/go/ebs for the latest information.
Software requirements
•For backup and restore to Virtual Tape Library targets you need software that supports tape
libraries and autoloaders. This software resides on the host, not the HP StoreOnce Backup
system. The device may be used with the major backup applications from HP, Symantec,
EMC, Computer Associates and others.
•For backup and restore to Catalyst store targets, the HP StoreOnce Catalyst OST 2.0 plugin
must be installed on each Media Server that is required to write data to the StoreOnce Catalyst
stores.
Refer to http://www.hp.com/go/ebs for the latest compatibility information.
Recommended web browser settings
The web browser used to communicate with the HP StoreOnce Backup system must have Active
Scripting or JavaScript enabled. If it does not, some of the browser buttons may not be displayed.
The web interface is supported on Internet Explorer, Firefox and Chrome. Please refer to http://
www.hp.com/go/ebs for the latest information about which browser versions are supported.

In this chapter:
•Installing the rail kit (page 9)
•Mounting the HP StoreOnce Backup System (page 9)
•Connecting the hardware (page 11)
•Connecting to the Capacity Upgrade Kit (optional) (page 13)
IMPORTANT: See also the Safety Booklet on the HP StoreOnce Backup system CD-ROM.
Installing the rail kit
The supplied rail kits allow you to install the HP StoreOnce Backup system into square and round
hole racks for 1U and 2U servers. If mounting the HP StoreOnce Backup system into threaded hole
or telco racks, please refer to http://www.racksolutions.com to purchase the required mounting
hardware.
This installation is to be performed by qualified individuals who have knowledge of the procedures,
precautions, and hazards associated with equipment containing hazardous electrical circuits.
WARNING! These rails, when installed, form only a shelf for the server to rest on. The server is
not attached to the rail by any other means. Use extreme caution when pulling the server out from
the rack; it can slip and fall, causing damage to the server or injury. HP is not responsible for any
damage or injury caused by the mishandling of the server.
WARNING! Ensure that the rack is level and stable before working on the rack. Be sure the
leveling jacks (feet) extend to the floor and that the full weight of the rack rests firmly on the floor.
WARNING! Ensure that the rack has anti-tip measures in place. Such measures may include
floor-bolting, anti-tip feet, ballast, or a combination of these as specified by the rack manufacturer
and applicable codes.
WARNING! Ensure that sufficient personnel are on hand to support the product(s) during the
installation process. Use of the appropriate lifting device is recommended as an installation aid.
WARNING! Always load the rack from the bottom up. Load the heaviest items in the rack first.
This makes the rack bottom-heavy and helps prevent it from becoming unstable.
WARNING! Do not overload the branch circuit that provides power to the rack. The total rack
load should not exceed 80 percent of the branch circuit rating.
Mounting the HP StoreOnce Backup system
WARNING! Ensure that sufficient personnel are on hand to support the product(s) during the
installation process. Use of the appropriate lifting device is recommended as an installation aid.
1. Install the rails in the rack, as required. Follow the instructions provided separately with the
rail kits.

Dicovering the HP StoreOnce Backup system on the network
If you have used the Quick Install option of connecting LAN Port 1 to a DHCP-enabled 1GbE
network, you will be able to manage the StoreOnce Management Console from any client attached
14 Powering on and managing the StoreOnce Management system

to the same network using the appliance's Fully Qualified Domain Name (FQDN). Once connected,
you can run the StoreOnce CLI network commands to optimize your network configuration.
If your network is not DHCP enabled or you have attached to a different network port, you will
need to connect a monitor with keyboard directly to the appliance to configure network settings
manually using the StoreOnce CLI commands. Once configured, you may use the CLI or GUI, as
appropriate, to manage the appliance.
NOTE: The net set wizard StoreOnce CLI command guides you through a series of questions,
using the answers you provide to configure the appliance on your network. See Network
configuration (page 17) for more information and network configuration examples.
Accessing the StoreOnce Management Console
There are three ways of accessing the StoreOnce Management Console:
•Using the StoreOnce Command Line Interface, CLI
•Using the StoreOnce Web Management Interface, GUI
The StoreOnce CLI
The StoreOnce Command Line Interface (CLI) provides a way of administering and monitoring the
system. Some tasks, such as network configuration, snmp configuration and date and time
configuration, can only be carried out from the StoreOnce CLI. See the HP StoreOnce CLI Reference
Guide for more information about the StoreOnce CLI commands and their syntax.
1. StoreOnce CLI commands require an SSH client application (freely available from the internet)
and must be run from a SSH terminal session on a machine that is on the same network as
the StoreOnce appliance:
ssh <username>@<ip_address>
NOTE: They can also be run from a local console (Keyboard and Monitor) attached to the
appliance, for example, if the network is not yet configured.
2. At the prompts provide a User Name and Password (Admin, admin).
The StoreOnce GUI
The HP StoreOnce Management Console is the main interface for:
•Monitoring the status and health of the HP StoreOnce Backup system and all configured backup
devices
•Creating and modifying VTL and NAS StoreOnce backup targets and Catalyst stores (VTL
backup targets may also be created and managed using the StoreOnce CLI)
•Managing replication relationships and housekeeping
To log on to the Management Console using the StoreOnce GUI, use any machine connected to
the same network as the appliance. The HP StoreOnce Backup system uses a secure network
connection.
1. Enter: https://<IP_address>
You may also use the Fully Qualified Domain Name (FQDN)
NOTE: If you use http: in the URL, you are automatically forwarded to the https: secure
network connection.
Accessing the StoreOnce Management Console 15

2. The StoreOnce Management Console displays the Login prompt. Provide a User Name and
Password (Admin, admin).
NOTE: The web browser used to communicate with the StoreOnce Backup system must have
Active Scripting or JavaScript enabled. If it does not, some of the browser buttons may not be
displayed.
User accounts
There are two types of user account: admin and user. Two users, one for each account type, are
created automatically when the system is installed:
•Administrator: This account allows authorized users to create and edit management and
StoreOnce functions via the GUI and CLI. The initial user name and login is Admin and admin,
but the Admin user may change this via the GUI or CLI. Any password change applies to both
the GUI and CLI.
•Operator: This account is available if the administrator wishes to provide limited access to the
GUI and CLI to certain users whose access will be restricted to monitoring and viewing. The
initial user name and login is Operator and operator, but the Admin user may change this
via the GUI or CLI.
Users with an Admin login can create additional users after installation. See the HP StoreOnce
Backup system user guide for more information.

4 Network configuration
In this chapter:
•Networking overview (page 17)
•The network configuration wizard (page 18)
•More about the configuration file (page 22)
•Default network configuration (page 22)
•Identifying network ports (page 23)
•Network configuration examples not using the wizard (page 24)
Networking overview
The HP StoreOnce Backup system supports IPv4 only. Networking parameters are contained within
a network configuration file.
There are three options when configuring the network for the first time.
•For ease of installation, a default configuration file is supplied with the StoreOnce Backup
system. As long as LAN port 1 of the appliance is connected to a DHCP–enabled 1GbE
network switch, the HP StoreOnce Backup system will be immediately active on the network
after installation.
The user then has the option of continuing to use the default configuration file or creating and
applying an additional configuration file that is tailored to their exact networking requirements.
This is done via the StoreOnce CLI using an SSH application such as PuTTy.
NOTE: If DHCP is supported, it is recommended that once an IP address has been assigned,
the system Administrator should permanently associate that IP address with the StoreOnce
Backup system. This will avoid any problems with the IP address of the device changing over
reboots.
To find out the IP address that has been assigned, connect to the CLI using a console (keyboard
and monitor) and use the StoreOnce CLI command:
nl
net show status all
•There is a single StoreOnce CLI wizard command, net set wizard. This command provides
a prompted sequence of steps to enable full configuration of network settings. It creates and
activates a new configuration file. See The network configuration wizard (page 18).
•It is also possible to create and modify configuration files manually. When a configuration
file is activated, it becomes the Current file. See also More about the configuration
file (page 22).
When is the default configuration file not adequate?
The default configuration file is adequate if the main use of the Ethernet network will be to access
the StoreOnce Management Console (GUI and Command Line Interface) remotely. However, many
users will require more flexible networking configurations. For example:
•The use of all available ports to connect to multiple subnets; each subnet could have a different
function, such as iSCSI VTL, NAS, Catalyst, replication, depending upon the estimated volume
of data and performance requirements for the various StoreOnce functions
•Bonding of available ports to provide link aggregation and failover
The HP StoreOnce 4400 Backup system family has two 10GbE ports as well as two 1GbE
ports. A recommended configuration might be a bonded subnet on the 10GbE network for
Networking overview 17

transferring data between network clients and Backup system, and a bonded subnet on the
1GbE ports for management of the appliance on a 1GbE subnet.
•Users who do not have a DHCP-enabled 1GbE network, or who do not want to connect to
LAN port 1 must create and activate a network configuration file before their system can
become active on the network. This network configuration file may use any available Ethernet
port, but one must always be connected for access to the StoreOnce Management Console
remotely.
Network bonding modes
Each pair of network ports on the appliance can be configured either on separate subnets or in a
bond with each other (1GbE and 10GbE ports cannot be bonded together).
Three bonding modes are supported:
•Mode 1 (Active/Backup)
This is the most simple bonding mode; it allows network traffic via one active port only and
requires no specific extra switch configuration. It is recommended for simple network
connections, if the active network link fails then traffic moves to the backup port.
•Mode 4 (IEEE 802.3ad Dynamic Link Aggregation)
This bonding mode is also known as LACP and requires a special external switch configuration.
It provides a link aggregation solution, increasing the bond physical bandwidth but can only
work if all the ports in the bond are connected to one switch or switches joined by an interswitch
link. It is recommended when :
◦The customer wants to increase throughput to the StoreOnce appliance
◦Trunks between switches on the customer network already use LACP mode
The LACP protocol only works when it is configured on both the server and StoreOnce end
of the connection. Please refer to your switch documentation for information on LACP
configuration.
•Mode 6 (Active Load Balancing)
This mode provides a load balance solution. It does not require specific external switch
configuration, but does require the switch to allow ARP negotiation. It can be used in a 2–switch
configuration.
This configuration is generally recommended for backup data performance and also for
resiliency of both data and management network connectivity. However, in some environments
ARP packet negotiation may be disabled within the network infrastructure, so this mode may
not be appropriate.
NOTE: It should be noted that when using bonded ports the full performance of both links will
only be realized if multiple host servers are providing data, otherwise data will still use only one
network path from the single server.
The network configuration wizard
The wizard will guide you through the configuration of network settings on your StoreOnce Backup
system.
If you wish to make additions or modifications to an existing network configuration without having
to reconfigure all settings then use the net modify or net add CLI commands instead, as
described in the HP StoreOnce Backup system CLI Reference guide.
The wizard consists of the following steps:
18 Network configuration

1. Set system wide DNS server addresses.
2. Configure network settings for available network adapters.
3. Save and apply all network settings.
You can select Quit+ENTER at any time to exit the wizard.
When assigning static IP settings, the required information is:
•An IP Address for the device e.g. 192.168.1.50
•Subnet Mask e.g. 255.255.255.0
•Default Gateway (address of the server or router which provides external network connection)
e.g. 192.168.1.1
Optional information is:
•Domain Name (domain extension for the device) e.g. hp.com
•DNS server addresses (address of the server which translates hostnames to IP addresses) e.g
192.168.1.1
Before running the wizard
Before running the wizard you must make a number of decisions about your network configuration.
1. Do you wish to configure DNS servers? Up to 3 may be configured. Make sure you have the
address details before you start.
2. Are you connecting a single port or are you connecting two ports to your network?
3. Which Ethernet port(s) are you connecting? Bonded pairs will be eth0 and eth1 for HP
StoreOnce 2620/4210/4220 Backup systems. For the other HP StoreOnce Backup systems,
eth0/eth1 are the 1GbE ports; eth4/eth5 are the 10GbE ports. You cannot bond a 1GbE
with a 10GbE port.
4. Which network bonding mode is required, the default is Active/Passive bonding?
5. Does your network use DHCP or static IP addresses? If you select static IP addressing, make
sure you know:
•IP address of the HP StoreOnce Backup system
•Subnet mask
•Gateway IP address (optional, the gateway can also be obtained from DHCP)
•Domain name, such as mycompany.com (optional, the domain name can also be obtained
from DHCP)
6. The above information is sufficient to configure the network and once entered, the wizard will
display and ask you to confirm the settings you have specified. At this point, do you wish to
configure a second subnet? For example, you may wish to dedicate one network to replication.
Or, with HP StoreOnce 4430/4420 Backup systems, you may wish to use the 10GbE network
for data and the 1GbE network for StoreOnce management.
You will be prompted to provide details of the second subnet, as above. You are also asked
to select which subnet will provide the default gateway.
To run the wizard
1. To run the wizard, connect a console directly to the appliance and, using puTTY (or other
ssh application, log into the StoreOnce CLI.
2. Enter the command:
net set wizard
The network configuration wizard 19

3. Follow the instructions provided in the wizard text. Prompts appear in the following sequence.
•Step 1: DNS addresses (optional)
•Step 2: Subnet configuration. The prompts displayed in this section will vary depending
upon the responses you make to the prompts for your network configuration. It is at the
end of this step that you are given the opportunity of configuring a second subnet.
•Step 3: Network configuration summary. The final step provides network configuration
details. If you are satisfied that the network is configured correctly, key 1 to finish the
wizard and apply the settings.
4. Your network is now configured and you can access the HP StoreOnce Backup system remotely
via the StoreOnce GUI or CLI. Be sure to save a copy of the configuration, as described in
the HP StoreOnce Backup system user guide. If you need to make subsequent changes to the
network configuration, use the StoreOnce CLI, as described in the HP StoreOnce CLI Reference
Guide.
