module: hpilo_boot
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.
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
media:
description:
- The boot media to boot the system from
required: false
default: network
choices: [ "cdrom", "floppy", "hdd", "network", "normal", "usb" ]
image:
description:
- The URL of a cdrom, floppy or usb boot media image.
C(protocol://username:password@hostname:port/filename)
- protocol is either C(http) or C(https)
- username:password is optional
• - port is optional
required: false
state:
description:
- The state of the boot media.
- no_boot: Do not boot from the device
- boot_once: Boot from the device once and then notthereafter
- boot_always: Boot from the device each time the serveris rebooted
- connect: Connect the virtual media device and set to boot_always
- disconnect: Disconnects the virtual media device and set to no_boot
required: true
default: boot_once
choices: [ "boot_always", "boot_once", "connect", "disconnect", "no_boot" ]
force:
description:
- Whether to force a reboot (even when the system is already booted)
required: false
default: no
choices: [ "yes", "no" ]
examples:
- code: |
local_action: hpilo_boot host=$ilo_address login=$ilo_login password=$ilo_password match=$inventory_hostname_short media=cdrom image=$iso_url
only_if: "'$cmdb_hwmodel'.startswith('HP ')
description: Task to boot a system using an ISO from an HP iLO interface only if the system is an HP server
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
C(using delegate)_to.
