Oracle ILOM Overview

Oracle Integrated Lights Out Manager (Oracle ILOM) provides advanced service processor (SP) hardware and software that you can use to manage and monitor the servers and switches in Oracle Big Data Appliance Rack. Oracle ILOM dedicated hardware and software is preinstalled on these components. ILOM automatically initializes as soon as power is applied.

Oracle ILOM enables you to actively manage and monitor servers in Oracle Big Data Appliance regardless of the operating system state, providing you with a reliable Lights Out Management (LOM) system.

With ILOM, you can proactively:

• Learn about hardware errors and faults as they occur

• Remotely control the power state of a server

• View the graphical and non-graphical consoles

• View the current status of sensors and indicators on the system

• Determine the hardware configuration of your system

• Receive generated alerts about system events in advance

The ILOM service processor runs its own embedded operating system and has a dedicated Ethernet port, which together provide out-of-band management capability. In addition, you can access ILOM from the server operating system (Oracle Linux). Using ILOM, you can remotely manage Oracle Big Data Appliance as if you were using the local KVM.

Oracle ILOM Interfaces

Oracle ILOM supports two interfaces for accessing its features and functions. You can choose to use a browser-based web interface or a command-line interface.

Web Interface

The web interface enables you use a browser to log in to the SP, then to perform system management and monitoring.

Command-Line Interface

The command-line interface (CLI) enables you to operate ILOM using keyboard commands and adheres to industry-standard DMTF-style CLI and scripting protocols. ILOM supports SSH v2.0 and v3.0 for secure access to the CLI. Using the CLI, you can reuse existing scripts and automate tasks using familiar interfaces.

Oracle ILOM Users

Oracle ILOM on Oracle Big Data Appliance is configured with these two users:

• ilom-admin: Provides the write privileges needed to change the system configuration, without the full power of root.

• ilom-operator: Provides read-only privileges to monitor the system.

Administrative Network Diagram

Figure 6-1 illustrates the management/ILOM network. It shows two of the 18 servers and the two Sun Network QDR InfiniBand Gateway Switches. The Cisco Ethernet management switch is connected to the servers and the InfiniBand switches.

ILOM IP Addresses for Oracle Big Data Appliance Rack Components

You require at least one static IP address for Service Processor (ILOM access). For the list of default ILOM IP addresses assigned to Oracle Big Data Appliance Rack components at the time of manufacturing, see "Factory Network Settings".

After you reconfigure these IP addresses during the initial configuration of the Oracle Big Data Appliance using Oracle Big Data Appliance Configuration Utility, you must use those IP addresses to access ILOM.

Connecting to ILOM Using the Network

You can typically access ILOM using the network over an Ethernet connection. You must know the ILOM Ethernet address. Before system configuration, the address is the factory IP address setting. After system configuration, you can use either the component name or IP address listed in the Configuration Worksheet. You can use either the CLI or the browser interface to access ILOM. Alternatively, you can launch a remote KVM session to access ILOM.

Note:

You can use this connection method when ILOM IP addresses can be accessed over the network. Oracle recommends that you use this connection method to access ILOM. See Chapter 8, "Configuring Oracle Big Data Appliance."

This section discusses the following topics:

• Connecting to the Command-Line Interface

• Connecting to the Web GUI

• Opening a Remote KVM Session

Connecting to the Command-Line Interface

1. Open an SSH client, such as PuTTY.

2. In the Host Name (or IP address) field, enter the ILOM name or IP address of the component to connect to. For example, before configuration, you might enter the factory default IP address of 192.168.1.203 for a Sun Network QDR InfiniBand Gateway Switch. After configuration, you might enter the new IP address or a name such as bda1sw-ib2.

3. Ensure that SSH is chosen as the Connection Type.

4. Type the user name and the password, when prompted. The default user name is root, and the default password is welcome1.

   The CLI command prompt (#) is displayed.

5. Enter help for a list of commands.

Connecting to the Web GUI

1. Open a web browser and navigate to the ILOM name or IP address of an Oracle Big Data Appliance server or switch.

   The login screen is displayed.

2. Enter the user name and the password. The administrative user name is ilom-admin, and the default password is welcome1.

   Note: Use the passwd command to change the password.

3. Click Log In.

   The web GUI is displayed, as shown in Figure 6-2.

Opening a Remote KVM Session

To access the ILOM consoles for Oracle Big Data Appliance components that are connected to ILOM:

1. Ensure that pop-up blockers are disabled in your browser before you launch the remote console.

2. Type the ILOM IP address in the address bar of a web browser.

3. Log in to ILOM using the administrative user name and password (ilom-admin and welcome1). After login, the ILOM home page is displayed.

4. Click the Remote Control tab, and click Launch Remote Console.

   The remote console is displayed.

Connecting to ILOM Using a Serial Connection

You can connect to ILOM using a serial connection if you are unable to access ILOM using the network due to any of the following problems:

• Misconfiguration of the network

• Misconfiguration of ILOM IP addresses

• Misconfiguration of Cisco Ethernet switch ports

• Sideband configuration issues

Connecting to a Server ILOM

To connect to ILOM of an Oracle Big Data Appliance server using a serial connection:

1. Attach a serial cable from a terminal or a PC running terminal emulation software to the SER MGT port of an Oracle Big Data Appliance server. The cable should be 15 feet or shorter.

2. Verify that your terminal or laptop is operational.

3. 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, but can be set to any standard rate up to 115200)

   • Disable software flow control (XON/XOFF)

   • Disable hardware control

4. Verify that power is supplied to either PSU.

   If there is power applied to either PSU, then ILOM will be functional regardless of the power state of the servers.

5. Press Enter on the terminal device. A connection between the terminal device and the ILOM is established.

   The ILOM login prompt is displayed.

6. Log in to the CLI using the administrative user name and the password (ilom-admin and welcome1).

   The ILOM default command prompt is displayed.

Connecting to ILOM of a Sun Network QDR InfiniBand Gateway Switch

To connect to ILOM of a Sun Network QDR InfiniBand Gateway Switch using a serial connection:

1. Attach a USB-to-Serial connector to the USB port of the switch.

2. Verify that your terminal or laptop is operational.

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

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

   • 115200 baud

   • Disable software flow control (XON/XOFF)

   • Disable hardware control

4. Press the Return or Enter key on the serial device several times to synchronize the connection.

   You may see text similar to the following:

   where nm2name is the host name of the management controller. The name might be the word hostname.

   Even if you do not see the text, go to Step 5.

5. Type root for the login name followed by the root password of welcome1. The # prompt is displayed.

   Note:

   If you do not see this output or prompt, there is a problem with the serial configuration, the USB-to-Serial connector, or the CLI.

Using ipmitool Commands When SP Network Information Is Lost

If the service processor (SP) network information gets lost, you can use an SSH shell to connect to the ETH0 interface of the operating system on a server and issue ipmitool commands to reconfigure network settings. For example, this command resets the ILOM root password:

ipmitool sunoem cli 'set /SP/users/rootpassword=somepasswd' password

For a list of ipmitool commands, issue the command without arguments:

ipmitool
