ILOM Initial Setup

This chapter describes how to do the ILOM initial setup.

The ILOM communicates through the system serial port and/or through a dedicated Ethernet port.

Connecting with the Ethernet requires some configuration.

This chapter contains the following sections:


2.1 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 software to the RJ-45 serial port on the ILOM board.

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:

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 from the serial port on the server's back panel to a terminal device.

Refer to your -specific documentation or the supplement for the location of the serial port.



Note - The serial port requires that the serial cable connected to it use the following pin assignments. Note that these are the same as the serial cable connector for the Sun Advanced Lights Out Manager (ALOM) or Remote System Control (RSC). See TABLE 2-1.

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 up or during its power up sequence, you will see bootup messages.



When the system 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 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.

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

->

The ILOM is now 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/MB

7. To go to the host serial console (host COM0), type the following commands:

cd /SP/console

start



Note - After you have returned to the serial console, to switch back to the CLI, enter the Escape-( key sequence.



Chapter 3 describes how to use the CLI.

For instructions on how to use the serial console, see the platform-specific documentation.


2.2 Connecting to the ILOM Using an Ethernet Connection

To access the full range of ILOM functionality, you must connect a LAN to the Ethernet port and configure your Ethernet connection.

ILOM supports Dynamic Host Configuration Protocol (DHCP) and static IP addressing.

2.2.1 Configure the IP Address Using 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 the system power cable to a power source.

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

2. If you are going to use DHCP, verify that your DHCP server is configured to accept new media access control (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. Fill in the IPMI 2.0 Configuration page.

a. Under IP Assignment, select DHCP or Static.

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

7. 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.



2.2.2 Configuring the ILOM to use DHCP

To configure the ILOM to use a DHCP address:

1. Verify that your DHCP server is configured to accept new media access control (MAC) addresses.

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

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

3. Obtain the ILOM MAC address from one of the following locations.

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.

4. Connect an Ethernet cable to the RJ-45 NET MGT Ethernet port.

Refer to your platform documentation or the supplement for the location of RJ-45 NET MGT Ethernet port.

5. You can assign an Ethernet address directly, or you can let DHCP assign one for you.

a. To assign your own Ethernet address, use the DHCP configuration software to assign an IP address to the MAC address noted above. See the DHCP server documentation for details.

b. To let DHCP assign an IP address:



Note - Different DHCP server applications running on different operating systems store these log files in different locations. Consult your DHCP system administrator to locate the correct path to the log file.



i. When you connect an Ethernet cable to the ILOM, the ILOM provides its MAC address and DHCP assigns the ILOM an IP address.

ii. Log in to your DHCP server and view its DHCP log file.

iii. Identify the IP address in the log file that corresponds to the ILOM MAC address.

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.

When this procedure is complete, you can access the ILOM using the IP address assigned by DHCP.

2.2.3 Configuring the ILOM to Use a Static IP Address

Usually, you will configure the ILOM to use DHCP, as described in Section 2.2.2, Configuring the ILOM to use DHCP.

If you choose to configure the ILOM using a static IP address, you can do so using three different methods:

2.2.3.1 Obtain the ILOM IP Address

Before you begin, you must obtain the ILOM IP address from one of the following locations. Record the IP address for future reference.



Note - You can set the IP address using the BIOS Setup Utility.

If the address on the IPMI configuration page is acceptable, you do not need to change anything.

To change the IP address, type the new address in the IP address field. Type in a new subnet mask and default gateway if necessary. When you are done, click Commit.

See Section 2.2.1, Configure the IP Address Using BIOS Setup Utility for details.



2.2.3.2 Configuring a Static IP Address Using CLI and a Serial Connection

To set a static IP address for the ILOM using the CLI and a serial line connection, do the following.

1. Establish a serial connection to the ILOM.

See Section 2.1, Connecting to the ILOM Using a Serial Connection for details.

2. Log in to the ILOM.

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

cd /SP/network

4. Type the following commands to specify a static Ethernet configuration.

set pendingipaddress=xxx.xxx.xx.xx

set pendingipnetmask=yyy.yyy.yyy.y

set pendingipgateway=zzz.zzz.zz.zzz

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 obtain the ILOM IP address, see Section 2.2.3.1, Obtain the ILOM IP Address.

5. Log out of the ILOM.

2.2.3.3 Configuring a Static IP Address Using CLI and Ethernet

1. Log in to the ILOM using Secure Shell (SSH) over the network, or by connecting a terminal to the serial port.

To establish a Secure Shell (SSH) connection to the CLI, type the appropriate connection command in the SSH application. For example, to connect to the ILOM with an IP address of 129.144.82.20, type the following command:

# ssh -l root 129.144.82.20

Use the IP address you obtained in Section 2.2.3.1, Obtain the ILOM IP Address.

2. Type the following command to set the working directory.

cd /SP/network

3. Type the following commands to specify a static Ethernet configuration.



Note - The following values are samples only. You must specify the IP address, netmask, and gateway appropriate for your ILOM and network configuration.



set pendingipaddress=129.144.82.26

set pendingipnetmask=255.255.255.0

set pendingipgateway=129.144.82.254

set pendingipdiscovery=static

set commitpending=true

2.2.3.4 Configuring a Static IP Address Using the WebGUI

To set a static IP address for the ILOM using the WebGUI, do the following.

1. Connect to the ILOM through a web browser running on a remote system.

Use the IP address you obtained in Section 2.2.3.1, Obtain the ILOM IP Address.
