Managing the Sun Blade Server Module With ILOM

Sun Integrated Lights Out Manager (ILOM) is system management firmware that you can use to monitor, manage, and configure the Sun Blade server module. The ILOM firmware is preinstalled on the service processor (SP) of each Sun Blade server module and initializes as soon as you apply power to the system. You can access ILOM through several interfaces, such as web browsers, a command-line interface (CLI), a Simple Network Management Protocol (SNMP) interface, and an Intelligent Platform Management Interface (IPMI). ILOM will continue to run regardless of the state of the host operating system, making it a “lights-out” management system.

For information about configuring and using ILOM, refer to the Sun Integrated Lights Out Manager 2.0 User’s Guide (820-1188). You can download this document from:

http://docs.sun.com

Service Processor

The service processor (SP) is the ILOM firmware. It has its own Internet Protocol (IP) address and media access control (MAC) address and is capable of operating regardless of the state of the other system hardware. In a Sun Blade server module, the SP can operate whether the server module is fully operational, powered down, or in standby mode.

Chassis Monitoring Module

The Sun Blade Modular System, or chassis, has its own service processor, called a chassis monitoring module (CMM). CMM ILOM is a modified version of ILOM firmware that is preinstalled for the SP.

ILOM on the Server Module SP and CMM

ILOM supports two ways to manage a system: using the CMM or using the server module’s SP directly.

• Using the CMM SP - Managing the system from the CMM enables you to set up and manage components throughout the entire chassis system, as well as to manage an individual server module SP.
• Using the Server Module SP - Managing the SP on a Sun Blade server module enables you to manage operations on an individual server module. This approach might be useful when troubleshooting a specific service processor, controlling access to a specific server module, or installing operating system software to a specific server module.

Connecting to ILOM

You can establish communication with the ILOM Server Module SP through a local or remote console.

• Local console. Connect a serial console to the local serial management port on the server module or Chassis Monitoring Module (CMM).
• Remote console. Attach a local area Ethernet network cable to the network management port on the CMM.

For instructions on connecting a local serial console or attaching an Ethernet cable, refer to the Sun Blade X6240 Server Module Installation Guide (820-3968).

The type of connection you establish to ILOM determines which type of system management tasks you can perform. For example, to remotely access the full range of system management functionality in ILOM, you will require an Ethernet connection to the CMM and an IP assignment for the CMM and the server module SP.

You can connect to the ILOM on your server module using one of the following methods:

• Option 1 - When the server module is installed in a chassis, it is automatically connected to the same subnet as the CMM ILOM. This allows you to use Ethernet to connect to both the web GUI and the command-line interface (CLI).

• Option 2 - Use the serial connector on the chassis to connect to the chassis CMM ILOM. Then use the CMM ILOM to navigate to the server module. This connection supports CLI access only.
• Option 3 - Use a dongle cable to establish a serial connection directly to the server module. This connection supports CLI access only.

The following sections describe each of these methods. FIGURE 1 shows the connections.

FIGURE 1 ILOM Connection Options

Typically, you connect to ILOM through the Ethernet. When the server module is installed in the chassis, its ILOM is automatically accessible on the same subnet as the CMM ILOM.

If you do not know ILOM's IP address, find it as described in Finding ILOM's IP Address.

You can connect to ILOM using a Secure Shell (SSH) to connect to the command line interface (CLI), or using a browser to connect to the web interface.

• To connect to the CLI, see Connecting to the ILOM CLI.
• To connect to the web interface, see Connecting to the ILOM Web Interface.

To find ILOM's IP address:

1. Log in to the CMM.

See the Sun Integrated Lights Out Manager 2.0 User’s Guide (820-1188) for details.

2. Type the command:

show /CH/BLn/SP/network

Where n is 0 through 9 for server modules 0 through 9, respectively

Temperature, Voltage, and Fan Sensors

The server module includes a number of sensors that generate entries in the system event log (SEL) when the sensor crosses a threshold. Many of these readings are used to adjust the fan speeds and perform other actions, such as illuminating LEDs and powering off the chassis.

You can also configure sensors to generate IPMI PET traps as, described in the Sun Integrated Lights Out Manager 2.0 User’s Guide (820-1188).

This section describes the sensors and provides details about their operation.

Caution - Do not use any interface other than the ILOM CLI or web interface to alter the state or configuration of any sensor or LED. Doing so could void your warranty.
