This section provides the initialization and setup steps for the Data Domain DD6300 backup appliances that are used in the commercial and enterprise backup solutions.
Initializing the Data Domain system
Accepting the End User License Agreement
Power on the Data Domain appliance and connect to the Serial Comms port. The first time that you log in to a Data Domain system, the End User License Agreement (EULA) is displayed. At the end of the EULA, you are prompted to accept the agreement.
Later, to redisplay and accept the EULA, run:
system show eula
Running the configuration wizard
The CLI configuration wizard starts automatically the first time that the system starts. The wizard prompts you through a series of questions for initial system configuration and basic network connectivity.
Note: You can start the CLI configuration wizard manually by running the config setup command.
Configuring the management network
Configure the management network as follows:
- At the Network Configuration prompt, type yes to configure the system for network connectivity.
- At the Use DHCP prompt, type yes to configure DHCP (Dynamic Host Configuration Protocol) to dynamically obtain network parameters (such as, the hostname, domain name, and IP addresses) from a DHCP server; otherwise, type no to configure the parameters manually.
- At the following prompt, enter an FQDN for the hostname, or accept the hostname if the system discovered it:
Enter the hostname for this system (fully-qualified domain name):
- At the following prompt, enter the Domain Name System (DNS) domain name—for example, yourcompany.com—or accept the domain name if the system discovered it:
Domainname Enter your DNS domainname :
- At the following prompts, enable and configure each Ethernet interface, accepting or declining DHCP for each interface by typing yes or no respectively.
If the port does not use DHCP to discover network parameters automatically, enter the information manually. For the management network setup, disable all other ports except for ethMa. In the next section, we set up the other ports by using the management web UI.
Ethernet port eth0d
Enable Ethernet port eth0a (yes|no|?) [yes]:
Ethernet port ethMa
Enable Ethernet port eth0b (yes|no|?) [no]:
Use DHCP on Ethernet port eth0b (yes|no|?) [no]:
Enter the IP address for eth0b [192.168.10.185]:
Enter the netmask for eth0b [255.255.255.0]:
- At the following prompt, enter the IP address of the default routing gateway or accept the default gateway if the system discovered it:
Enter the default gateway IP address:
- At the IPV6 Default Gateway prompt, enter the IPv6 address of the default routing gateway or accept the IPv6 address of the default gateway if the system discovered it. If IPv6 is not in use, leave the field empty, and press Enter to continue.
- At the DNS Servers prompt, take one of the following actions:
- Enter IP addresses for up to three DNS servers for resolving hostnames; for multiple addresses, use a comma-separated or space-separated list.
- Enter a space for no DNS servers.
- Accept the IP addresses of the DNS servers if the system discovered them.
- When the summary of the network settings is displayed, take one of the following actions:
- Enter Save to accept the settings.
- Enter Cancel to reject the settings and exit to the CLI.
- Enter Retry to display your previous responses for each prompt; press Enter to accept the displayed value or enter a new value.
The following configuration is a generic example of the Data Domain hostname and network interfaces:

----- ------- ----- ---- ------------ ------------------------
Do you want to save these settings (Save|Cancel|Retry):
- Enter Save to save the configuration.
- Open a browser and enter the newly configured management IP address to continue the setup using the Data Domain management UI.
Using the Data Domain management UI to set up licenses and back up the network
- Log in to the Data Domain web UI.
- On the Licenses page of the Configuration wizard, when asked if you want to configure the licenses, click Yes to set up the licenses or No to skip the setup.
- On the Network page, click Yes to configure the network, which is used for the database backup.
- On the General page under Network, select Manually Configure, and enter the hostname, domain name, and gateway, as shown in the example in the following figure:
Figure 11. Network configuration
- On the Interfaces page under Network, enable the interface that you are using for your backup network and provide a static IP and netmask, as shown in the following example:
Figure 12. Interface settings
In our solution, we used two interfaces, eth3a and eth3b. The interfaces must be on the same subnet as your public IP address for the Data Domain appliance to communicate with the database servers.
- On the DNS page under Network, select or enter your DNS, and then click Next.
- On the Summary page under Network, review the summary and click Submit to update the network settings.
Figure 13. Network settings summary
- Do not configure anything else. Click No when prompted to configure the file system, system settings, and so on.
Enabling the file system
- SSH into the management IP of the Data Domain appliance and enter the following command to enable the file system with the default configuration:
- Verify that the file system is enabled:
Enabling DD Boost software
To enable DD Boost software, on the side panel in the Data Domain UI, go to Protocols > DD Boost and click Enable.
The following figure shows that the DD Boost software is enabled:

Add Interface Groups
After you enable DD Boost for Enterprise Applications, add Interface Groups:
- Go to the IP Network tab and select the default Interface Groups.
- Add the IP addresses of the interfaces to which you previously assigned IP addresses.
The following figure shows the interfaces:
