Oracle ILOM is system management firmware that is preinstalled on some SPARC servers. ILOM enables you to actively manage and monitor components installed in your server. ILOM provides a browser-based interface and a command-line interface, as well as SNMP and IPMI interfaces.
The ILOM service processor runs independently of the server and regardless of the server power state as long as AC or DC power is connected to the server. When you connect your server to AC or DC power, the ILOM service processor immediately starts up and begins monitoring the server. All environmental monitoring and control is handled by ILOM.
The -> prompt indicates that you are interacting with the ILOM service processor directly. This prompt is the first prompt you see when you log in to the server. through the serial management port or network management port, regardless of the host’s power state.
You can also access the ILOM service processor prompt (->) from the OpenBoot ok prompt, or from the Oracle Solaris # or % prompt, provided the system console is configured to be accessible through the serial management and network management ports.
The ILOM service processor supports a total of ten concurrent sessions per server: four SSH connections available through the network management port and one connection available through the serial management port.
