Connecting to ILOM

This section describes how to connect to the ILOM located in the Virtualized NEM.

Note - The Sun Blade 6000 Modular System chassis has its own ILOM, called a CMM ILOM, which is a separate entity from the NEM ILOM. It is described in the Sun Integrated Lights Out Manager 2.0 Administration Guide

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

**TABLE B-1 ILOM Connection Options**
Option Number	Connection Method	User Interface	More Information
1	Ethernet	Web interface or CLI	Option 1 - Ethernet
2	Serial - CMM	CLI only	Option 2 - Chassis Serial Connector
3	Serial - NEM	CLI only	Option 3 - NEM Serial Connector

Note - The CMM ILOM in the chassis has an Ethernet switch that supports connections to the Virtualized NEM and its ILOMs. To use this connection, you must be connected to the same subnet as the ILOM, and you must know the NEM ILOM’s Ethernet address.

FIGURE B-1 shows a graphical representation of the ILOM connection options.

FIGURE B-1 ILOM Connection Options

Option 1 - Ethernet

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

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

To connect to the CLI, see To Connect to the CLI.
To connect to the web GUI, see To Connect to the WebGUI.

If you do not know the ILOM's IP address, find it as described in the following procedure.

To Find the ILOM’s IP Address

Log in to the CMM.

See the Integrated Lights Out Manager (ILOM) Administration Guide For the Sun Blade 6000 Modular System, 820-0052 for details.

Type the command:

show /CH/NEMn/SP/network

where n is the NEM number.

The CLI displays information about the NEM, including its IP address.

For example:

-> show /CH/NEM0/SP/network
 
 /CH/NEMN/SP/network
    Targets:
 
    Properties:
        type = Network Configuration
        commitpending = (Cannot show property)
        ipaddress = IPaddress
        ipdiscovery = dhcp
        ipgateway = IPgateway
        ipnetmask = 255.255.252.0
        macaddress = Macaddress
        pendingipaddress = Ipaddress
        pendingipdiscovery = dhcp
        pendingipgateway = IPgateway
        pendingipnetmask = 255.255.252.0

Option 2 - Chassis Serial Connector

The chassis serial connector connects to the chassis CMM ILOM. The CMM ILOM provides a command to connect to the NEM ILOM(s).

To Connect to ILOM Through the Chassis Serial Connector

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

The terminal device can be an actual terminal, a laptop running a terminal emulator, or a terminal server. It must be set to the following:

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)

The cable requires the following pin assignments.

Pin	Signal Description
1	Request To Send (RTS)
2	Data Terminal Ready (DTR)
3	Transmit Data (TXD)
4	Ground
5	Ground
6	Receive Data (RXD)
7	Data Carrier Detect (DCD)
8	Clear To Send (CTS)

Press Enter on the terminal device.

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

The CMM ILOM login prompt appears.

SUNCMMnnnnnnnnnn login:

The first string in the prompt is the default host name. It consists of the prefix SUNSP and the CMM ILOM’s MAC address.

Log in to the CMM ILOM.

The default user is root and the default password is changeme.

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

Temperature, Voltage, and Fan Sensors

The NEM 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 NEM.

These sensors can also be configured to generate IPMI PET traps as, described in the Sun Integrated Lights Out Manager 2.0 User’s Guide.

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

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

Board Sensor List lists the sensors. Sensor Details provides details about each sensor.

ILOM Proxy

In addition, a proxy ILOM CLI program is provided on the CMM to augment the core ILOM program’s ability to manage Virtualized NEMs and Sun Blade disk modules.

To take advantage of the module management capabilities offered by the proxy ILOM CLI, verify that you have the latest version of the proxy program installed. Refer to the Sun Blade 6000 Disk Module Configuration Guide for details about Multi-Fabric NEM software and firmware requirements.

Starting the ILOM Proxy CLI Program

Instructions for setting up and using ILOM are documented in the Sun Integrated Lights Out Manager 2.0 User’s Guide.

Prerequisite: To start the proxy CLI, a Virtualized Multi-Fabric 10GbE NEM module must be installed in the chassis in NEM slot 0.

To Start the ILOM Proxy CLI Program

Start the proxy program through the ILOM CLI. You can connect to the ILOM CLI by either of two methods:
- Connect a terminal or PC running a terminal emulator directly to the CMM serial port on your chassis.
- Connect to the Ethernet network management port using a secure shell (SSH).

After you are connected to the ILOM CLI, start the proxy CLI by typing the following command:
-> start /CH/NEM0/SP/cli
Note - The proxy CLI commands are case sensitive.

Enable or Disable IAL Dynamic Mode

You can enable or disable IAL dynamic mode either through the web interface or the CLI. See Enabling or Disabling the IAL for more information on when to enable IAL dynamic mode.
