Deploy Process
|
||||
~~~~~~~~~~~~~~
|
||||
* Admin configures the ProLiant bare metal node for iscsi_ilo driver. The
|
||||
ironic node configured will have the ``ilo_deploy_iso`` property in its
|
||||
``driver_info``. This will contain the glance UUID of the ISO
|
||||
deploy ramdisk image.
|
||||
* Ironic gets a request to deploy a glance image on the bare metal node.
|
||||
* ``iscsi_ilo`` driver powers off the bare metal node.
|
||||
* The driver generates a swift-temp-url for the deploy ramdisk image
|
||||
and attaches it as virtual media CDROM on the iLO.
|
||||
* The driver creates a small FAT32 image containing parameters to
|
||||
the deploy ramdisk. This image is uploaded to swift and its swift-temp-url
|
||||
is attached as virtual media Floppy on the iLO.
|
||||
* The driver sets the node to boot one-time from CDROM.
|
||||
* The driver powers on the bare metal node.
|
||||
* The deploy kernel/ramdisk is booted on the bare metal node. The ramdisk
|
||||
exposes the local disk over iSCSI and requests ironic conductor to complete
|
||||
the deployment.
|
||||
* The driver on the ironic conductor writes the glance image to the
|
||||
bare metal node's disk.
|
||||
* The driver bundles the boot kernel/ramdisk for the glance deploy
|
||||
image into an ISO and then uploads it to swift. This ISO image will be used
|
||||
for booting the deployed instance.
|
||||
* The driver reboots the node.
|
||||
* On the first and subsequent reboots ``iscsi_ilo`` driver attaches this boot
|
||||
ISO image in swift as virtual media CDROM and then sets iLO to boot from it.
|
||||
|
||||
Refer to `Netboot with glance and swift`_ for the deploy process of partition image
|
||||
and `Localboot with glance and swift`_ for the deploy process of whole disk image.

Deploy Process
|
||||
~~~~~~~~~~~~~~
|
||||
* Admin configures the ProLiant bare metal node for ``agent_ilo`` driver. The
|
||||
ironic node configured will have the ``ilo_deploy_iso`` property in its
|
||||
``driver_info``. This will contain the glance UUID of the ISO deploy agent
|
||||
image containing the agent.
|
||||
* Ironic gets a request to deploy a glance image on the bare metal node.
|
||||
* Driver powers off the bare metal node.
|
||||
* Driver generates a swift-temp-url for the deploy agent image
|
||||
and attaches it as virtual media CDROM on the iLO.
|
||||
* Driver creates a small FAT32 image containing parameters to
|
||||
the agent ramdisk. This image is uploaded to swift and its swift-temp-url
|

is attached as virtual media Floppy on the iLO.
|
||||
* Driver sets the node to boot one-time from CDROM.
|
||||
* Driver powers on the bare metal node.
|
||||
* The deploy kernel/ramdisk containing the agent is booted on the bare metal
|
||||
node. The agent ramdisk talks to the ironic conductor, downloads the image
|
||||
directly from swift and writes the node's disk.
|
||||
* Driver sets the node to permanently boot from disk and then reboots
|
||||
the node.
