5 Using Oracle Integrated Lights Out Manager (ILOM)

5.1 ILOM Overview

Oracle Integrated Lights Out Manager (ILOM) provides advanced service processor (SP) hardware and software that you can use to manage and monitor your Oracle Oracle Exalytics In-Memory Machine.

ILOM enables you to actively manage and monitor your Oracle Oracle Exalytics In-Memory Machine independently 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 your compute node

• View the graphical and non-graphical consoles for the host

• 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 via IPMI PETs, SNMP Traps, or E-mail Alerts.

The ILOM service processor (SP) 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 operating system (Oracle Linux) installed on the Oracle Oracle Exalytics In-Memory Machine. Using ILOM, you can remotely manage your compute node as if you were using a locally attached keyboard, monitor, and mouse.

ILOM automatically initializes as soon as power is applied to your compute node. It provides a full-featured, browser-based web interface and has an equivalent command-line interface (CLI).

5.2 Important Notes Before You Begin

You require at least one static IP address for Service Processor (ILOM access).

Note the following:

• As a general convention, root is used as the default user name.

• The default value of the Service Processor (SP ILOM) password is changeme.

5.3 Connecting to ILOM via the Network

Under normal circumstances, you can access ILOM via the network. You can use the Ethernet connection method to connect to the ILOM. You must know the ILOM IP address. The default ILOM IP address is 192.168.1.200. You can use either the CLI or the web interface to access ILOM. Alternatively, you can launch a remote KVM session to access ILOM.

This section discusses the following topics:

• Connecting to the CLI

• Connecting to the Web GUI

• Launching a Remote KVM Session

5.4 Connecting to ILOM via a Serial Connection

You can connect to ILOM via a serial connection if you are unable to access ILOM via 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

To connect to ILOM using a serial connection, complete the following steps:

1. Attach a serial cable from a terminal or a PC running terminal emulation software to the SER MGT port of your Oracle Oracle Exalytics In-Memory Machine. The cable should be of length 15 feet or less.

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 compute nodes.

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 default user name and the password (root and changeme).

   The ILOM default command prompt is displayed.

5.5 Configuring Network Access

You must configure network access after connecting to the ILOM using a serial connection or an Ethernet connection.

This section contains the following topics:

• Using a Serial Connection

• Using the Ethernet Connection

Using a Serial Connection

1. Connect to the ILOM using a serial connection, as described in Connecting to ILOM via a Serial Connection.

2. Run the following commands at the ILOM command prompt:

   cd /SP/network

   set pendingipdiscovery=static

   set pendingipaddress=<ip_address>

   set pendingipnetmask=<ip_netmask>

   set pendingipgateway=<ip_gateway>

   set pendingmanagementport=/SYS/MB/NET0

   set commitpending=true

Using the Ethernet Connection

1. Connect to the ILOM using the Ethernet connection, as described in Connecting to ILOM via the Network.

2. Run the following commands at the ILOM command prompt:

   cd /SP/network

   set pendingipdiscovery=static

   set pendingipaddress=<ip_address>

   set pendingipnetmask=<ip_netmask>

   set pendingipgateway=<ip_gateway>

   set pendingmanagementport=/SYS/MB/NET0

   set commitpending=true

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 the compute node and run appropriate ipmitool commands to reconfigure network settings, as in the following example:

/opt/ipmitool/bin/ipmitool sunoem cli 'set /SP/users/rootpassword=somepasswd' somepasswd

This example resets the ILOM root password.
