module: hpilo_boot
author: Dag Wieers (@dagwieers)
short_description: Boot system using specific media through HP iLO interface
description:
  - "This module boots a system through its HP iLO interface. The boot media
    can be one of: cdrom, floppy, hdd, network or usb."
  - This module requires the hpilo python module.

  force:
    description:
    - Whether to force a reboot (even when the system is already booted).
    - As a safeguard, without force, hpilo_boot will refuse to reboot a server that is already running.

    description:
      - Change the ssl_version used.
    default: TLSv1
    type: str

requirements:
- python-hpilo
notes:
- To use a USB key image you need to specify floppy as boot media.
- This module ought to be run from a system that can access the HP iLO
  interface directly, either by using C(local_action) or using C(delegate_to).
