Connecting and Initial Setup

This chapter describes how to connect to the ILOM and how to do the initial setup. It contains the following sections:

Section 2.1, Connecting to the ILOM

Section 2.2, Configuring the ILOM IP Address

2.1 Connecting to the ILOM

The way you connect to ILOM depends on whether it is in a rack-mounted server, or whether it is in a server module installed in a chassis.

TABLE 2-1 lists the different connection methods, and their relevance to rack-mounted servers and server modules in a chassis:

TABLE 2-1 Connection Methods
Connection Method	Rack- Mounted	Server Module	Supported Interface	Comments/Description
Ethernet	Yes	Yes	CLI and WebGUI	This is the normal method of connecting to the ILOM. You must know the ILOM's Ethernet address. Note: This is the only method that supports WebGUI access.
Serial, direct	Yes	No	CLI only	Connect directly to serial management port on server.
Serial, through dongle cable	No	Yes	CLI only	Connect a dongle cable directly to the server module.
Serial, through chassis/CMM	No	Yes	CLI only	Log in to the CMM, navigate to server module, then execute command to start ILOM.

The following sections describe each method.

2.1.1 Connecting to the ILOM Using an Ethernet Connection

The Ethernet connectivity provides full access to the ILOM CLI and WebGUI.

For rack mounted servers, you must connect a LAN to the Ethernet port and configure your Ethernet connection.

For server modules in a chassis, you must connect a LAN to the NET MGT port on the chassis. When a server module is installed in a chassis, the ILOM is automatically connected to the same subnet as the CMM ILOM.

Note - Some server modules have different (non-ILOM) service processors. See the documentation provided with the server module for more details.

To connect to the Ethernet, you must know the ILOM's IP address. To discover, and or to configure the ILOM IP address, see Section 2.2.1, Viewing the ILOM IP Address for more information.

Note - The ILOM supports a maximum of 10 active sessions, including serial, ssh, and WebGUI sessions. You can view active sessions by entering the command show /SP/sessions from the CLI.

Connecting to the CLI

1. Start your ssh client.

2. To log in to the ILOM, type:

$ ssh username@ipaddress

where username is the user ID, and ipaddress is the IP address of the ILOM. The default user is root.

3. Type your password when prompted.

The default is changeme.

The CLI command prompt appears.

Connecting to the WebGUI

For more detailed instructions, see Section 4.2, Logging In to the WebGUI.

1. To log in to the WebGUI, type the IP address of the ILOM into your web browser.

The login screen appears.

2. Type your user name and password.

When you first try to access the WebGUI, it prompts you to type the default user name and password. The default user name and password are:

Default user name: root

Default password: changeme

The default user name and password are in lowercase characters.

3. Click Log In.

The WebGUI appears.

4. To log out of the WebGUI, click Log Out at the top right of the WebGUI.

The logout screen appears.

Caution - Do not use the Log Out button in your web browser to log out from the WebGUI.

2.1.2 Connecting to the ILOM Using a Serial Connection

You can access the ILOM CLI at any time by connecting a terminal or a PC running terminal emulation.

For rack-mounted systems, connect the cable directly to the RJ-45 or DB9 serial port.

For many server modules in a chassis, you have to connect a dongle cable directly to the server module, and connect a the terminal to the DB9 connector on the dongle cable. You might also require a DB9 to RJ-45 serial adapter.

For other server modules, you can connect directly to the serial port on the server module.

See the server module documentation for additional details.

1. Verify that your terminal, laptop, or terminal server is operational.

2. Configure the terminal device or the terminal emulation software to use the following settings:

8N1: eight data bits, no parity, one stop bit

9600 baud (default, can be set to any standard rate up to 57600)

Disable software flow control (XON/XOFF)

3. Unpack your server and connect the system power cable to a power source.

Refer to your platform-specific documentation for instructions on installing the hardware, cabling, and powering on.

4. Connect a serial cable to the server or server module.

For rack-mounted servers, connect a serial cable from the serial port on the server's back panel to a terminal device.

For server modules, connect a dongle cable directly to the server module, and connect a the terminal to the DB9 connector on the dongle cable using a DB9 to RJ-45 serial adapter.

Refer to your platform-specific documentation for additional details.

5. Press Enter on the terminal device.

This establishes the connection between the terminal device and the ILOM.

Note - If you connect a terminal or emulator to the serial port before it has been powered on or during its power on sequence, you will see bootup messages.

When the server has booted, the ILOM displays its login prompt:

SUNSPnnnnnnnnnn login:

The first string in the prompt is the default host name. It consists of the prefix SUNSP and the ILOM's media access control (MAC) address. The MAC address for each ILOM is unique.

6. Log in to the CLI:

a. Type the default user name: root.

b. Type the default password: changeme.

When you have successfully logged in, the ILOM displays the ILOM default command prompt:

->

The ILOM is accessing the CLI. You can now run CLI commands.

For example, to display status information about the motherboard in your server, type the following command:

-> show /SYS/PROC

7. When you are done, type exit to quit.

Chapter 3 describes how to use the CLI.

2.1.3 Connecting to the ILOM through the CMM

The chassis serial connector connects to the CMM ILOM, which provides a command to connect to the server module ILOM. This connection requires a terminal or a PC running terminal emulation software to the RJ-45 serial port on the chassis.

This section applies only to systems that meet the following requirements:

The server module must be installed in a chassis equipped with a Chassis Management Module (CMM) ILOM.

See the chassis documentation for additional details.

The server module must be equipped with an ILOM. Some server modules have different service processors.

See the server module documentation for additional details.

1. Verify that your terminal, laptop, or terminal server is operational.

2. Configure that terminal device or the terminal emulation software to use the following settings:

8N1: eight data bits, no parity, one stop bit

9600 baud (default, can be set to any standard rate up to 57600)

Disable software flow control (XON/XOFF)

3. Connect a serial cable from the serial port on the chassis to a terminal device.

Refer to the chassis documentation for the location of the serial port.

4. Press Enter on the terminal device.

This establishes the connection between the terminal device and the CMM ILOM.

The CMM ILOM displays its login prompt:

SUNCMMnnnnnnnnnn login:

The first string in the prompt is the default host name. It consists of the prefix SUNCMM and the CMM ILOM's MAC address. The MAC address for each service processor is unique.

5. Log in to the CLI:

a. Type the default user name, root.

b. Type the default password, changeme.

Once you have successfully logged in, the CMM ILOM displays its default command prompt:

->

You are now connected to the CMM ILOM CLI.

6. Navigate to the server module ILOM by typing this command:

cd /CH/BLn/SP/cli

Where n is number of the server module.

7. Enter the command start.

A prompt appears.

8. Enter y to continue or n to cancel.

If you entered y, the server module ILOM prompts for its password.

Note - The CMM ILOM logs on to the server module ILOM using the user name in the user target under /CH/BLn/SP/cli (where n is the server module number). See the chassis documentation for additional details.

9. Enter the password when prompted.

The default is changeme.

The server module ILOM prompt appears.

10. When you are done, type exit.

The server module ILOM exits and the CMM CLI prompt appears.

2.2 Configuring the ILOM IP Address

You can configure the ILOM IP address using one of several methods:

Using the BIOS Setup Utility. See Section 2.2.3, Configuring the IP Address Using the BIOS Setup Utility.

Using the CLI. See Section 2.2.4, Configuring the ILOM Using the CLI.

Using the WebGUI. See Section 2.2.5, Configuring the IP Address Using the WebGUI.

2.2.1 Viewing the ILOM IP Address

To find the ILOM IP address:

1. Log in to the ILOM CLI using any of the methods described in Section 2.1, Connecting to the ILOM.

To use the Ethernet ssh connection, you must already know the IP address.

2. Type the command:

To see all the IP address-related information, type:

show /SP/network

To see only the IP address, type:

show /SP/network/ipaddress

2.2.2 Using DHCP to Assign an IP Address

Most installations use DHCP to assign an IP address to the ILOM. To use DHCP, the following conditions must be present:

A DHCP server must be connected to the same subnet as the ILOM.

The DHCP server must be configured to accept new MAC addresses.

The ILOM must be configured to use DHCP. This is its default setting.

If the ILOM is not configured to use DHCP, you can configure it using any of the following sections:

Section 2.2.3, Configuring the IP Address Using the BIOS Setup Utility

Section 2.2.4, Configuring the ILOM Using the CLI

Section 2.2.5, Configuring the IP Address Using the WebGUI

If these conditions are present, when the ILOM is powered on or reset, DHCP automatically assigns it an IP address.

Note - Some DHCP servers allow you to specify the IP address that it will assign to the ILOM. In this case, the ILOM still must be configured for a "dynamic" IP address, even though DHCP's choice of addresses is "static."

Finding the ILOM's MAC Address

The ILOM has a unique MAC address that is different from the server or server module's MAC address. You might need this address to configure your DHCP server software.

MAC addresses are 12-digit hexadecimal strings in the format xx:xx:xx:xx:xx:xx where x represents a single hexadecimal letter (0-9, A-F, a-f). Write down that address for future reference.

You can obtain the ILOM MAC address in one of the following ways:

Start the ILOM CLI and enter the command show /SP/network. The ILOM displays its MAC address.

For rack-mounted servers, there is a label attached to the GRASP board. Open the cover of the server to view this label.

Check the Customer Information Sheet shipped with your server.

The system BIOS setup screen. Choose Advanced - IPMI 2.0 Configuration - Set LAN Configuration - MAC address.

Using the MAC Address to Find the IP Address

Once the ILOM has been assigned an IP address by DHCP, you can use the MAC address to identify that IP address by looking in the DHCP log file.

Typically, DHCP log file entries are individual lines with the following comma-separated fields:

ID, Date, Time, Description, IP Address, Host Name, MAC Address

Locate the MAC address of your ILOM in the MAC Address (seventh) field of the correct DHCP file entry, and record the corresponding value of the IP address (fifth) field. This is the IP address that you must use to access the WebGUI and the remote console.

2.2.3 Configuring the IP Address Using the BIOS Setup Utility

The BIOS Setup Utility allows you to set the ILOM IP address. It allows you to configure it manually, or use DHCP.

1. Unpack your server and connect it to a power source.

Refer to your platform documentation for details.

2. If you are going to use DHCP, verify that your DHCP server is configured to accept new MAC addresses.

3. Start the BIOS Setup Utility.

a. Boot the system.

b. Watch the boot messages. You will see a line that says you can press F2 to enter BIOS setup.

c. After you see the message, press F2.

After some messages and screen changes, the BIOS Setup Utility appears.

4. Select the Advanced tab.

The Advanced page appears.

5. Highlight IPMI 2.0 Configuration in the list, then select Enter.

The IPMI 2.0 Configuration page appears.

6. Highlight LAN Configuration then select Enter.

The LAN Configuration page appears.

7. Fill in the IPMI 2.0 Configuration page.

8. Under IP Assignment, select DHCP or Static.

If you selected Static, fill in the IP address, subnet mask and default gateway at the bottom of the page.

If you select DHCP, your installation must meet the conditions described in Section 2.2.2, Using DHCP to Assign an IP Address.

9. Select Commit to save your changes.

If you selected DHCP, the BIOS utility automatically updates the address fields.

Caution - You must use Commit to save the changes on this page. Using F10 will not save your changes.

2.2.4 Configuring the ILOM Using the CLI

To configure the ILOM IP address using the CLI, do the following.

1. Connect to the ILOM CLI using one of the methods described in Section 2.1, Connecting to the ILOM.

2. Log in to the ILOM.

3. Type the following command to set the working directory:

cd /SP/network

4. Configure the IP address:

To configure a static IP address, type:

set pendingipaddress=xxx.xxx.xx.xx

set pendingipnetmask=yyy.yyy.yyy.y

set pendingipgateway=zzz.zzz.zz.zzz

set pendingipdiscovery=static

set commitpending=true

where xxx.xxx.xx.xx, yyy.yyy.yyy.y and zzz.zzz.zz.zzz are the IP address, netmask, and gateway for your ILOM and network configuration.

To configure a dynamic IP address, type:

set pendingipdiscovery=dhcp

set commitpending=true

If you configure the ILOM to use DHCP, your installation must meet the conditions described in Section 2.2.2, Using DHCP to Assign an IP Address.

5. Log out of the ILOM.

2.2.5 Configuring the IP Address Using the WebGUI
