15.1 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 an Oracle Big Data Appliance rack. Oracle ILOM dedicated hardware and software is preinstalled on these components. It 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 Oracle 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 nongraphical 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 Oracle 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 Oracle ILOM from the server operating system (Oracle Linux). Using Oracle ILOM, you can remotely manage Oracle Big Data Appliance as if you were using a local KVM.

15.1.1 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, and then to perform system management and monitoring.

Command-Line Interface

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

15.1.2 Oracle ILOM Users

The Oracle Big Data Appliance servers are configured initially with only the root user.

The InfiniBand switches are configured with these additional 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.

As root, you can create additional ILOM users if you want.

15.2 Administrative Network Diagram

Figure 15-1 illustrates the administrative Oracle 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.

15.3 Oracle ILOM IP Addresses for Oracle Big Data Appliance Components

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

After you reconfigure these IP addresses using Oracle Big Data Appliance Configuration Generation Utility, you must use the reconfigured IP addresses to access Oracle ILOM.

15.4 Connecting to Oracle ILOM Using the Network

You can typically access Oracle ILOM using the network over an Ethernet connection. You must know the Oracle 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 the IP address listed in the Installation Template. You can use either the CLI or the browser interface to access Oracle ILOM. Alternatively, you can launch a remote KVM session (Sun Fire X4270 M2-based racks only).

Note:

You can use this connection method when Oracle ILOM IP addresses can be accessed over the network. Oracle recommends that you use this connection method. See Configuring an Oracle Big Data Appliance Full Rack or Starter Rack

This section discusses the following topics:

15.4.1 Connecting to the Command-Line Interface

To connect to the Oracle ILOM command-line interface follow these steps.

  1. Open a secure shell (SSH) client, such as PuTTY.
  2. In the Host Name (or IP address) field, enter the Oracle 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 provided by the Oracle Install Coordinator.

    The CLI command prompt (#) is displayed.

  5. Enter help for a list of commands.
