Web Management Interface; Troubleshooting; Data Deduplication - HP D2D Installation

Further information about networks
The two physical network ports provide three network configuration modes:
• Single Port Configuration: The HP D2D is connected to one network; only one network
port is used (Port 3).
• Dual Port Configuration: The HP D2D is connected to two different networks. Both
network ports are used.
• High Availability (Port Failover) Configuration: Both network ports are used, but the
two ports are bound together to provide port failover.
• High Availability (Link Aggregation): This creates a bonded network port and provides
load balancing across the two network ports.
Single port configuration is the default mode, but it may easily be changed during the
software installation, discovery and configuration process or subsequently from the Web
Management Interface. If dual port configuration is required, the networks must be on
different sub-nets.
The High Availability mode is the recommended option, because it provides port failover
and increased bandwidth, but both network ports must be connected to the same switch
and it must support port bonding.
For further information please refer to the "User Guide" on the CD-ROM.
NOTE: The HP D2D supports the IPv6 protocol, but it is factory-configured to
recognize both IPv4 and IPv6 protocols and use either, for example if the internet
service provider (ISP) uses an IPv4 network. No further user configuration is required.

Software installation, discovery and
configuration
There are three possible stages to installation. You may not need to complete all of them.
1 Optional: If you will be configuring Virtual Tape Devices, install all the required
drivers. This step is not required if you intend to use only NAS shares.
2 Mandatory: Discover and configure the HP D2D Backup System on the network.
3 Optional: Create a base iSCSI library configuration to get started. This step is not
required if you intend to use only NAS shares or only FC devices on the HP D2D.
NOTE: For networks using the IPv4 protocol (most networks), Dynamic (DHCP)
network addressing is enabled by default on the HP D2D. If your network supports
DHCP, all the required network parameters will be set automatically. If your network
uses static IP addressing, you will need to manually assign network settings - IP
address, subnet mask and gateway. Make sure that you have these ready before you
start installation.
If you are on an IPv6-only network, simply enter the MAC address of the HP D2D
into the wizard when requested, which can then be used to find the IP address and
required network parameters automatically. You will find the MAC address on the
label on the top of the unit.
Windows users:
The recommended way to set up your HP D2D Backup System network is to run the
Installation wizard from the HP StorageWorks CD-ROM supplied with your product. The
Installation wizard should be run on all hosts that are to be backed up to the HP D2D
Backup System.
1. Insert the CD-ROM into the host machine and the Installation wizard will auto run. In
most instances the installation completes all three stages detailed above successfully.
For more detailed information about what happens during each stage and about
iSCSI, please refer to the "User Guide" on the HP StorageWorks CD-ROM.
2. Run the Installation wizard on the other hosts that are to be backed up.
Linux and UNIX users:
Download the latest patches for your operating system. For configuration instructions, please
refer to the "Linux and UNIX Configuration Guide" on the HP StorageWorks CD-ROM.

Web Management Interface

To run the Web Management Interface:
• From a Windows host server or PC: Use the desktop shortcut created by the Installation
wizard or
• From any machine connected to the network: Enter https: followed by the IPv4 IPv6
address or name (fully qualified domain name) of the HP D2D Backup System into the
web browser.
The default Sign On is Administrator with a password of Admin. Both names are case
sensitive. (The password can be changed after installation.)
The device created during installation will appear to the backup software on your host
server or PC as a locally-attached backup device. This backup device can be seen only
by the host and not by any other devices on the network.
Use the Web Management Interface to:
• Monitor the status and health of the HP D2D Backup System and all configured
backup devices.
• Create NAS Shares as targets for disk backup.
• Create slot mappings and configure replication, if required.
• If you have created a Virtual Tape device as the backup target, change the number of
cartridge slots or create additional library devices for a host.
NOTE: To power off your HP D2D Backup System always use the Web Management
Interface, as described in the "User Guide" on the HP StorageWorks CD-ROM.

Using your D2D
Backup Software
If you are backing up to NAS shares on the HP D2D Backup System you need software
that supports backup to disk. You must configure a new backup job in your application.
If you are backing up to Virtual Tape Libraries on the HP D2D, you need software that
supports backup to HP Tape libraries. You can incorporate the HP D2D into your existing
tape rotation schemes. For example scenarios see the "User Guide" on the HP
StorageWorks CD-ROM.
Always refer to www.hp.com/go/connect, to ensure that you are running supported
software and install any recommended updates.

Data deduplication

The HP D2D incorporates data deduplication technology. Deduplication is applied on a
per device basis; it is always enabled for NAS shares, but may be disabled for Virtual
Tape devices. As data is backed up to a device, the HP D2D analyzes the data at block
(not file) level and stores only data that is unique, creating pointers to blocks that are
already stored on that device. (It does not reference data stored on other devices.) This is
an extremely efficient way of using the available storage space. See the "User Guide" for
more information.
Replication
Replication allows users to replicate data from cartridges on one HP D2D to mapped
slots on another HP D2D on a remote site. Once configured (using the simple-to-use
wizard), replication occurs automatically, ensuring data is mirrored on source and target
HP D2Ds. Deduplication ensures that network traffic is minimized.
Understanding the LEDs
Item Description Status
Steady blue identifies the HP D2D in the rack.
1 HP D2D beacon LED
2 System health LED Green = Normal operation
Flashing amber = Degraded condition
Flashing red = Critical condition
Network port
3&4 Off = no network connection or network not
configured
Flashing green - network connection
5 Power button LED Off = no power connected
Steady green = power connected, device ready for use
Steady amber = device switched off or in hibernation
with power connected

Troubleshooting

Detailed help is available while running the Installation wizard. If you encounter
problems during any of the the installation phases, it will advise you what steps to take.
For more troubleshooting information, refer to the "User Guide" on the HP StorageWorks
CD-ROM. This guide also contains reference information about iSCSI and RAID. If you
cannot resolve problems, contact HP Support at www.hp.com/support.
