Power the Host On and Off Using Oracle ILOM

Language:

This procedure provides Oracle ILOM web and command-line interface (CLI) instructions to remotely power on or power off the host.

Caution - Data loss. An immediate shutdown abruptly closes all applications and files without saving changes.

Control power using the Oracle ILOM web interface or the CLI.
You must be logged on with administrator privileges. For details, see Connecting to Oracle ILOM.
- From the web interface:
  Note - These commands affect power to the host but not to the SP. To completely power off the server, you must disconnect the power cords from the back panel of the server.

  2. From the Select Action list box, select one of the following:
    - Reset — Assert a power-cycle to a managed server, while keeping power applied to system components such as disk drives.
    - Graceful Reset — Gracefully shut down the host operating system prior to power-cycling the managed server.
    - Immediate Power Off — Directly shut down the power to the managed device.
    - Graceful Shutdown and Power Off — Gracefully shut down the host operating system prior to shutting down the power to the managed device.
    - Power On — Apply full power to the managed device.
    - Power Cycle — Turn off system power to all system components, and then apply full power to all system components.
  3. Click Save, and then click OK.
