Power the Host On and Off Using Oracle ILOM

Language:

This procedure provides Oracle ILOM web interface and CLI instructions to remotely power on or power off the host.

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.

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 Using Oracle ILOM.
- From the web interface:
  1. In the left pane, click Host Management → Power Control.
  2. In the Select Action list box, select one of the following:
    - Reset — Assert a power cycle to the server, while keeping power applied to system components such as hard disk drives.
    - Immediate Power Off — Directly shut down the power to the service.
    - Graceful Shutdown and Power Off — Gracefully shut down the host operating system prior to shutting down the power to the server.
    - Power On — Apply Main power to the server.
    - Power Cycle — Turn off system power to all system components, and then apply Main power to all system components.
  3. Click Save, and then click OK.
- From the CLI, enter one of the following commands:
  - reset /SYSTEM
  - stop /SYSTEM
  - stop -f /SYSTEM
  - start /SYSTEM
