Configuring the Appliance

The Sun StorageTek 5220 NAS Appliance ships with the operating system installed. To configure the appliance for the first time, complete the following tasks:

Provide an IP address

Use the Web Administrator's Configuration Wizard.

Assigning the IP Address

You can assign an IP address in either of the following ways:

Using a Dynamic Host Configuration Protocol (DHCP) server to assign the IP address automatically. Your network must have either a DHCP server or a DHCP relay agent, which has access to a DHCP server on another network. The DHCP server or agent assigns an IP address to the Sun StorageTek 5220 NAS Appliance whenever it is powered on while connected to the network. If a DHCP server is not available, you must assign the IP address manually.

Using the controls and liquid crystal display (LCD) panel on the Sun StorageTek 5220 NAS Appliance to enter the IP address manually.

To Prevent an Address Assignment

If a DHCP server is available on your network but you prefer to assign the IP address manually, you must prevent the appliance from acquiring an IP address automatically by using the following procedure:

1. During the power-on sequence, wait for the following message to display in the LDC panel: "DHCP Discovery NIC X"

2. Press any key on the LCD panel.

3. When the panel displays the message, "Abort DHCP?" press the ENTER button on the panel to confirm.

4. Follow the instructions in To Assign the IP Address Manually.

To Assign the IP Address Manually

If a DHCP server is not available or if you prefer to assign a permanent IP address to the appliance, configure the IP address using the LCD panel.

1. Turn on the Sun StorageTek 5220 NAS Appliance and wait for the power-on sequence to complete.

Note - If you have a DHCP server, skip the discovery step. When the LCD panel displays "DHCP Discovery NIC X" status message, press any key on the LCD panel to display the "Abort DHCP?" message. Press the ENTER button.

The LCD panel displays the following:

A: Set IP Number

B: Retry DHCP

2. Press the ENTER button to select A.

3. Enter the values for the IP address.

To enter data, use the up and down arrow buttons to change the value of the digits and press the ENTER button to confirm the value you want. The cursor moves to the next digit. After you set the last digit, press the ENTER button again to proceed to the next setting.

You can enter values for the following settings or you can accept the default:

IP address

Subnet mask

Broadcast address

4. At the prompt about having a gateway, press Enter to accept the default of Yes.

The gateway indicates the network gateway.

After the gateway address is set, press the ENTER button to return to the Network Config menu.

To Display the IP Address

At the main menu of the LCD panel, press the ENTER button. At the prompt for Network Config settings, press the up arrow to A. Press the up or down arrow keys to select the network port and press the ENTER button to see the IP address.

Accessing the Web Administrator

Note - To use the Web Administrator, the appliance must be connected to your network, you must know its current IP address, and you must be logged into a client on the same network as the appliance.

When you connect to the Web Administrator for the first time, the Configuration Wizard launches automatically.

To Connect to the Web Administrator

1. From a client system on the same network as the appliance, open a web browser and type the IP address of the Sun StorageTek 5220 NAS Appliance in the address or location field, for example:

http://123.111.78.99

Press Enter.

Note - If the client system uses a proxy server and does not locate the appliance, change the browser's option to bypass the proxy server for local addresses. See your browser's online help or documentation for more information.

Your browser displays the Web Administrator's login screen. For your convenience, bookmark this location or add it to your Favorites list so that you do not have to enter the IP address in future sessions.

2. At the login screen, click Apply.

You can set the password at a later time, using the procedure in the Sun StorageTek NAS OS Administration Guide.

The Systems Operations, Set Time and Date panel is displayed.

3. Select the date, the time, and the time zone, and then click Apply.

This is the only time when the Web Administrator prompts for the date and time. If these values must be changed, use the Administrator Console.

4. Click Yes to confirm the date and time you set.

The Web Administrator displays the license agreement. Read the license agreement before you accept it. If you decline, Web Administrator displays the login screen.

5. Accept the license agreement.

The Web Administrator's Configuration Wizard starts. The wizard guides you through the process of configuring the Sun StorageTek 5220 NAS Appliance.

6. At each panel of the wizard, enter the information it requests. For descriptions of the panels, see the Sun StorageTek NAS OS Administration Guide.

If your system uses DHCP to assign DNS, WINS, or IP and gateway addresses, the fields for these values for port-emc1 (NET0) are configured automatically and you do not need to enter information. Verify the information or add information for other network ports and continue with the wizard.

Note - At the panel that requests the information for your DNS server, be sure to click the Add button on the panel before you continue with the wizard.

7. On the Confirmation screen, review the configuration you have set up. To change information, use the back arrow to return to a panel.

8. Click Finish on the Confirmation screen.

The system configures the settings and displays the Save Configuration screen.

9. Click Close on the Save Configuration screen.

The wizard checks that all mandatory information is complete and then reboots the appliance.

Next Steps

At this point, the storage system is running on your network but before it can store data, you need to set up your file system and to configure your users' access. Setting up a file system includes defining any logical unit numbers (LUNs), partitions, file volumes, or segments. When your file system is complete, set up user access rights and any other system management features such as setting up a local log file. For information on all these tasks and their concepts, see the Sun StorageTek NAS OS Administration Guide.

Note - The boot sequence log file is located in the bootlog, under /cvol/log. The file that the Web Administrator displays is a running log that can overflow. To save the entire log, set up a local log according to the instructions in the Sun StorageTek NAS OS Administration Guide.
