module: hpilo_facts
short_description: Gather facts through an HP iLO interface
description:
  - This module gathers facts for a specific system using its HP iLO interface.
    These facts include hardware and network related information useful
    for provisioning (e.g. macaddress, uuid).
  - This module requires the hpilo python module.
version_added: "0.8"
options:
  host:
    description:
      - The HP iLO hostname/address that is linked to the physical system.
    required: true
  login:
    description:
      - The login name to authenticate to the HP iLO interface.
    required: false
    default: Administrator
  password:
    description:
      - The password to authenticate to the HP iLO interface.
    required: false
    default: admin
  match:
    description:
      - An optional string to match against the iLO server name.
      - This is a safety measure to prevent accidentally using the wrong
        HP iLO interface with dire consequences.
    required: false
examples:
    - code: |
            local_action: hpilo_facts host=$ilo_address login=$ilo_login password=$ilo_password match=$inventory_hostname_short
            only_if: "'$cmdb_hwmodel'.startswith('HP ')
      description: Task to gather facts from a HP iLO interface only if the system is an HP server
    - description: Typical output of HP iLO_facts for a physical system
      code: |
            - hw_bios_date: "05/05/2011"
              hw_bios_version: "P68"

                macaddress_dash: "00-11-22-33-44-BA"

              hw_uuid: "123456ABC78901D2"
notes:
  - This module ought to be run from a system that can access the HP iLO
    interface directly, either by using C(local_action) or
    C(using delegate)_to.
