Oracle Integrated Lights Out Manager (ILOM) is system management firmware that is pre-installed on Oracle servers. The firmware enables you to actively manage and monitor components that are installed in the server. Oracle ILOM provides a web interface and a command-line interface (CLI), as well as Simple Network Management Protocol (SNMP) and Intelligent Platform Management Interface (IPMI) interfaces.
Oracle ILOM runs in the service processor (SP) independently of the server power-on state, while AC power is connected to the server. The SP immediately starts and begins monitoring the server when you connect the server to AC power. All environmental monitoring and control are handled by Oracle ILOM.
You can log in to an SP from a serial console connected to the SER MGT port or using ssh through the network connected to the NET MGT port. In each case, you see the -> prompt of the CLI for Oracle ILOM. This prompt enables you to interact with the SP through Oracle ILOM commands.
You can log into the Oracle ILOM web interface to the SP through the network connected to the NET MGT port by using the address http://ip-address-of-SP in your web browser.
The SP supports concurrent Oracle ILOM sessions per server. Multiple SSH or web connections are available through the NET MGT port, and one connection is available through the SER MGT port. For the M7 and M8 servers, you can have up to 25 concurrent SP sessions.
Certain Oracle ILOM tasks can be performed for the platform and for any available PDomain. This means that user roles must be properly assigned at the platform or domain level, and that specific commands must be provided for either the platform or PDomain.
The Oracle ILOM properties that affect power on self test (POST) behavior have changed. For information about specific properties, refer to the service manual for your platform. For more information on enabling SPARC diagnostic tests to run at boot, refer to the Oracle ILOM documentation in Related Information.
Oracle ILOM 4.0.x is included on M8 servers. On M7 servers, Oracle ILOM 3.2 is included and can be upgraded to version 4.0.x.
