iLO drivers

Overview

iLO drivers enable to take advantage of features of iLO management engine in HPE ProLiant servers. iLO drivers are targeted for HPE ProLiant Gen 8 systems and above which have iLO 4 management engine.

For more details, please refer the iLO driver document of Juno, Kilo and Liberty releases, and for up-to-date information (like tested platforms, known issues, etc), please check the iLO driver wiki page.

Currently there are 3 iLO drivers:

iscsi_ilo
agent_ilo
pxe_ilo.

The iscsi_ilo and agent_ilo drivers provide security enhanced PXE-less deployment by using iLO virtual media to boot up the bare metal node. These drivers send management info through management channel and separates it from data channel which is used for deployment.

iscsi_ilo and agent_ilo drivers use deployment ramdisk built from diskimage-builder. The iscsi_ilo driver deploys from ironic conductor and supports both net-boot and local-boot of instance. agent_ilo deploys from bare metal node and always does local-boot.

pxe_ilo driver uses PXE/iSCSI for deployment (just like normal PXE driver) and deploys from ironic conductor. Additionally it supports automatic setting of requested boot mode from nova. This driver doesn't require iLO Advanced license.

Prerequisites

proliantutils is a python package which contains set of modules for managing HPE ProLiant hardware.

Install proliantutils module on the ironic conductor node. Minimum version required is 2.1.7.:
```
$ pip install "proliantutils>=2.1.7"
```
ipmitool command must be present on the service node(s) where ironic-conductor is running. On most distros, this is provided as part of the ipmitool package. Refer to Hardware Inspection Support for more information on recommended version.

Different Configuration for ilo drivers

Glance Configuration

Configure Glance image service with its storage backend as Swift.
Set a temp-url key for Glance user in Swift. For example, if you have configured Glance with user glance-swift and tenant as service, then run the below command:
```
swift --os-username=service:glance-swift post -m temp-url-key:mysecretkeyforglance
```

Fill the required parameters in the [glance] section in /etc/ironic/ironic.conf. Normally you would be required to fill in the following details.:

[glance]
swift_temp_url_key=mysecretkeyforglance
swift_endpoint_url=https://10.10.1.10:8080
swift_api_version=v1
swift_account=AUTH_51ea2fb400c34c9eb005ca945c0dc9e1
swift_container=glance

The details can be retrieved by running the below command:

$ swift --os-username=service:glance-swift stat -v | grep -i url

StorageURL:     http://10.10.1.10:8080/v1/AUTH_51ea2fb400c34c9eb005ca945c0dc9e1
Meta Temp-Url-Key: mysecretkeyforglance

Swift must be accessible with the same admin credentials configured in Ironic. For example, if Ironic is configured with the below credentials in /etc/ironic/ironic.conf.:

[keystone_authtoken]
admin_password = password
admin_user = ironic
admin_tenant_name = service

Ensure auth_version in keystone_authtoken to 2.

Then, the below command should work.:

$ swift --os-username ironic --os-password password --os-tenant-name service --auth-version 2 stat

                     Account: AUTH_22af34365a104e4689c46400297f00cb
                  Containers: 2
                     Objects: 18
                       Bytes: 1728346241
Objects in policy "policy-0": 18
  Bytes in policy "policy-0": 1728346241
           Meta Temp-Url-Key: mysecretkeyforglance
                 X-Timestamp: 1409763763.84427
                  X-Trans-Id: tx51de96a28f27401eb2833-005433924b
                Content-Type: text/plain; charset=utf-8
               Accept-Ranges: bytes

Restart the Ironic conductor service.:
```
$ service ironic-conductor restart
```

Web server configuration on conductor

The HTTP(S) web server can be configured in many ways. For apache web server on Ubuntu, refer here

Following config variables need to be set in /etc/ironic/ironic.conf:

use_web_server_for_images in [ilo] section:
```
[ilo]
use_web_server_for_images = True
```

http_url and http_root in [deploy] section:

[deploy]
# Ironic compute node's http root path. (string value)
http_root=/httpboot

# Ironic compute node's HTTP server URL. Example:
# http://192.1.2.3:8080 (string value)
http_url=http://192.168.0.2:8080

use_web_server_for_images: If the variable is set to false, iscsi_ilo and agent_ilo uses swift containers to host the intermediate floppy image and the boot ISO. If the variable is set to true, these drivers uses the local web server for hosting the intermediate files. The default value for use_web_server_for_images is False.

http_url: The value for this variable is prefixed with the generated intermediate files to generate a URL which is attached in the virtual media.

http_root: It is the directory location to which ironic conductor copies the intermediate floppy image and the boot ISO.

Note

HTTPS is strongly recommended over HTTP web server configuration for security enhancement. The iscsi_ilo and agent_ilo will send the instance's configdrive over an encrypted channel if web server is HTTPS enabled.

Enable driver

Build a deploy ISO (and kernel and ramdisk) image, see BuildingDibBasedDeployRamdisk
See Glance Configuration for configuring glance image service with its storage backend as swift.

Upload this image to Glance.:

glance image-create --name deploy-ramdisk.iso --disk-format iso --container-format bare < deploy-ramdisk.iso

Add the driver name to the list of enabled_drivers in /etc/ironic/ironic.conf. For example, for iscsi_ilo driver:
```
enabled_drivers = fake,pxe_ssh,pxe_ipmitool,iscsi_ilo
```
Similarly it can be added for agent_ilo and pxe_ilo drivers.
Restart the ironic conductor service.:
```
$ service ironic-conductor restart
```

Drivers

iscsi_ilo driver

Overview

iscsi_ilo driver was introduced as an alternative to pxe_ipmitool and pxe_ipminative drivers for HPE ProLiant servers. iscsi_ilo uses virtual media feature in iLO to boot up the bare metal node instead of using PXE or iPXE.

Target Users

Users who do not want to use PXE/TFTP protocol on their data centres.
Users who have concerns with PXE protocol's security issues and want to have a security enhanced PXE-less deployment mechanism.

The PXE driver passes management information in clear-text to the bare metal node. However, if swift proxy server has an HTTPS endpoint (See EnableHTTPSinSwift for more information), the iscsi_ilo driver provides enhanced security by passing management information to and from swift endpoint over HTTPS. The management information, deploy ramdisk and boot images for the instance will be retrieved over encrypted management network via iLO virtual media.

Tested Platforms

This driver should work on HPE ProLiant Gen8 Servers and above with iLO 4. It has been tested with the following servers:

ProLiant DL380e Gen8
ProLiant DL580 Gen8 UEFI
ProLiant DL180 Gen9 UEFI
ProLiant DL360 Gen9 UEFI
ProLiant DL380 Gen9 UEFI

For more up-to-date information on server platform support info, refer iLO driver wiki page.

Features

PXE-less deploy with virtual media.
Automatic detection of current boot mode.
Automatic setting of the required boot mode, if UEFI boot mode is requested by the nova flavor's extra spec.
Supports booting the instance from virtual media (netboot) as well as booting locally from disk. By default, the instance will always boot from virtual media for partition images.
UEFI Boot Support
UEFI Secure Boot Support
Passing management information via secure, encrypted management network (virtual media) if swift proxy server has an HTTPS endpoint. See EnableHTTPSinSwift for more info. User image provisioning is done using iSCSI over data network, so this driver has the benefit of security enhancement with the same performance. It segregates management info from data channel.
Support for out-of-band cleaning operations.
Remote Console
HW Sensors
Works well for machines with resource constraints (lesser amount of memory).
Support for out-of-band hardware inspection.
Swiftless deploy for intermediate images
HTTP(S) Based Deploy.
iLO drivers with standalone ironic.

Requirements

iLO 4 Advanced License needs to be installed on iLO to enable Virtual Media feature.
Swift Object Storage Service - iLO driver uses swift to store temporary FAT images as well as boot ISO images.
Glance Image Service with swift configured as its backend - When using iscsi_ilo driver, the image containing the deploy ramdisk is retrieved from swift directly by the iLO.

Deploy Process

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.

Configuring and Enabling the driver

Refer to Glance Configuration and Enable driver.

Registering ProLiant node in ironic

Nodes configured for iLO driver should have the driver property set to iscsi_ilo. The following configuration values are also required in driver_info:

ilo_address: IP address or hostname of the iLO.
ilo_username: Username for the iLO with administrator privileges.
ilo_password: Password for the above iLO user.
ilo_deploy_iso: The glance UUID of the deploy ramdisk ISO image.
client_port: (optional) Port to be used for iLO operations if you are using a custom port on the iLO. Default port used is 443.
client_timeout: (optional) Timeout for iLO operations. Default timeout is 60 seconds.
console_port: (optional) Node's UDP port for console access. Any unused port on the ironic conductor node may be used.

For example, you could run a similar command like below to enroll the ProLiant node:

ironic node-create -d iscsi_ilo -i ilo_address=<ilo-ip-address> -i ilo_username=<ilo-username> -i ilo_password=<ilo-password> -i ilo_deploy_iso=<glance-uuid-of-deploy-iso>

agent_ilo driver

Overview

agent_ilo driver was introduced as an alternative to agent_ipmitool and agent_ipminative drivers for HPE ProLiant servers. agent_ilo driver uses virtual media feature in HPE ProLiant bare metal servers to boot up the Ironic Python Agent (IPA) on the bare metal node instead of using PXE. For more information on IPA, refer https://wiki.openstack.org/wiki/Ironic-python-agent.

Target Users

Users who do not want to use PXE/TFTP protocol on their data centres.
Users who have concerns on PXE based agent driver's security and want to have a security enhanced PXE-less deployment mechanism.

The PXE based agent drivers pass management information in clear-text to the bare metal node. However, if swift proxy server has an HTTPS endpoint (See EnableHTTPSinSwift for more information), the agent_ilo driver provides enhanced security by passing authtoken and management information to and from swift endpoint over HTTPS. The management information and deploy ramdisk will be retrieved over encrypted management network via iLO.

Tested Platforms

This driver should work on HPE ProLiant Gen8 Servers and above with iLO 4. It has been tested with the following servers:

ProLiant DL380e Gen8

Requirements

iLO 4 Advanced License needs to be installed on iLO to enable Virtual Media feature.
Swift Object Storage Service - iLO driver uses swift to store temporary FAT images as well as boot ISO images.
Glance Image Service with swift configured as its backend - When using agent_ilo driver, the image containing the agent is retrieved from swift directly by the iLO.

Deploy Process

Refer to Localboot with glance and swift for details.

Configuring and Enabling the driver

Refer to Glance Configuration and Enable driver.

Registering ProLiant node in ironic

Functionalities across drivers

Boot mode support

The following drivers support automatic detection and setting of boot mode (Legacy BIOS or UEFI).

pxe_ilo
iscsi_ilo
agent_ilo
When boot mode capability is not configured:
- If the pending boot mode is set on the node then iLO drivers use that boot mode for provisioning the baremetal ProLiant servers.
- If the pending boot mode is not set on the node then iLO drivers use 'uefi' boot mode for UEFI capable servers and "bios" when UEFI is not supported.
When boot mode capability is configured, the driver sets the pending boot mode to the configured value.
Only one boot mode (either uefi or bios) can be configured for the node.
If the operator wants a node to boot always in uefi mode or bios mode, then they may use capabilities parameter within properties field of an ironic node.

To configure a node in uefi mode, then set capabilities as below:
```
ironic node-update <node-uuid> add properties/capabilities='boot_mode:uefi'
```
Nodes having boot_mode set to uefi may be requested by adding an extra_spec to the nova flavor:
```
nova flavor-key ironic-test-3 set capabilities:boot_mode="uefi"
nova boot --flavor ironic-test-3 --image test-image instance-1
```
If capabilities is used in extra_spec as above, nova scheduler (ComputeCapabilitiesFilter) will match only ironic nodes which have the boot_mode set appropriately in properties/capabilities. It will filter out rest of the nodes.

The above facility for matching in nova can be used in heterogeneous environments where there is a mix of uefi and bios machines, and operator wants to provide a choice to the user regarding boot modes. If the flavor doesn't contain boot_mode then nova scheduler will not consider boot mode as a placement criteria, hence user may get either a BIOS or UEFI machine that matches with user specified flavors.

The automatic boot ISO creation for UEFI boot mode has been enabled in Kilo. The manual creation of boot ISO for UEFI boot mode is also supported. For the latter, the boot ISO for the deploy image needs to be built separately and the deploy image's boot_iso property in glance should contain the glance UUID of the boot ISO. For building boot ISO, add iso element to the diskimage-builder command to build the image. For example:

disk-image-create ubuntu baremetal iso

UEFI Secure Boot Support

The following drivers support UEFI secure boot deploy:

pxe_ilo
iscsi_ilo
agent_ilo

The UEFI secure boot can be configured in ironic by adding secure_boot parameter in the capabilities parameter within properties field of an ironic node.

secure_boot is a boolean parameter and takes value as true or false.

To enable secure_boot on a node add it to capabilities as below:

ironic node-update <node-uuid> add properties/capabilities='secure_boot:true'

Alternatively see Hardware Inspection Support to know how to automatically populate the secure boot capability.

Nodes having secure_boot set to true may be requested by adding an extra_spec to the nova flavor:

nova flavor-key ironic-test-3 set capabilities:secure_boot="true"
nova boot --flavor ironic-test-3 --image test-image instance-1

If capabilities is used in extra_spec as above, nova scheduler (ComputeCapabilitiesFilter) will match only ironic nodes which have the secure_boot set appropriately in properties/capabilities. It will filter out rest of the nodes.

The above facility for matching in nova can be used in heterogeneous environments where there is a mix of machines supporting and not supporting UEFI secure boot, and operator wants to provide a choice to the user regarding secure boot. If the flavor doesn't contain secure_boot then nova scheduler will not consider secure boot mode as a placement criteria, hence user may get a secure boot capable machine that matches with user specified flavors but deployment would not use its secure boot capability. Secure boot deploy would happen only when it is explicitly specified through flavor.

Use element ubuntu-signed or fedora to build signed deploy iso and user images from diskimage-builder. Refer BuildingDibBasedDeployRamdisk for more information on building deploy ramdisk.

The below command creates files named cloud-image-boot.iso, cloud-image.initrd, cloud-image.vmlinuz and cloud-image.qcow2 in the current working directory.:

cd <path-to-diskimage-builder>
./bin/disk-image-create -o cloud-image ubuntu-signed baremetal iso

Note

In UEFI secure boot, digitally signed bootloader should be able to validate digital signatures of kernel during boot process. This requires that the bootloader contains the digital signatures of the kernel. For iscsi_ilo driver, it is recommended that boot_iso property for user image contains the glance UUID of the boot ISO. If boot_iso property is not updated in glance for the user image, it would create the boot_iso using bootloader from the deploy iso. This boot_iso will be able to boot the user image in UEFI secure boot environment only if the bootloader is signed and can validate digital signatures of user image kernel.

Ensure the public key of the signed image is loaded into bare metal to deploy signed images. For HPE ProLiant Gen9 servers, one can enroll public key using iLO System Utilities UI. Please refer to section Accessing Secure Boot options in HP UEFI System Utilities User Guide. One can also refer to white paper on Secure Boot for Linux on HP ProLiant servers for additional details.

For more up-to-date information, refer iLO driver wiki page

Node Cleaning Support

The following iLO drivers support node cleaning -

pxe_ilo
iscsi_ilo
agent_ilo

For more information on node cleaning, see cleaning

Supported Automated Cleaning Operations

The automated cleaning operations supported are:
-reset_bios_to_default:
Resets system ROM settings to default. By default, enabled with priority
1. This clean step is supported only on Gen9 and above servers.
-reset_secure_boot_keys_to_default:

Resets secure boot keys to manufacturer's defaults. This step is supported only on Gen9 and above servers. By default, enabled with priority 20 .

-reset_ilo_credential:

Resets the iLO password, if ilo_change_password is specified as part of node's driver_info. By default, enabled with priority 30.

-clear_secure_boot_keys:

Clears all secure boot keys. This step is supported only on Gen9 and above servers. By default, this step is disabled.

-reset_ilo:

Resets the iLO. By default, this step is disabled.
For in-band cleaning operations supported by agent_ilo driver, see InbandvsOutOfBandCleaning.
All the automated cleaning steps have an explicit configuration option for priority. In order to disable or change the priority of the automated clean steps, respective configuration option for priority should be updated in ironic.conf.
Updating clean step priority to 0, will disable that particular clean step and will not run during automated cleaning.

Configuration Options for the automated clean steps are listed under [ilo] section in ironic.conf :

- clean_priority_reset_ilo=0
- clean_priority_reset_bios_to_default=10
- clean_priority_reset_secure_boot_keys_to_default=20
- clean_priority_clear_secure_boot_keys=0
- clean_priority_reset_ilo_credential=30
- clean_priority_erase_devices=10

For more information on node automated cleaning, see automated_cleaning

Supported Manual Cleaning Operations

The manual cleaning operations supported are:

-activate_license:

Activates the iLO Advanced license. This is an out-of-band manual cleaning step associated with management interface. See Activating iLO Advanced license as manual clean step for user guidance on usage. Please note that this operation cannot be performed using virtual media based drivers like iscsi_ilo and agent_ilo as they need this type of advanced license already active to use virtual media to boot into to start cleaning operation. Virtual media is an advanced feature. If an advanced license is already active and the user wants to overwrite the current license key, for example in case of a multi-server activation key delivered with a flexible-quantity kit or after completing an Activation Key Agreement (AKA), then these drivers can still be used for executing this cleaning step.
iLO with firmware version 1.5 is minimally required to support all the operations.

For more information on node manual cleaning, see manual_cleaning

Hardware Inspection Support

The following iLO drivers support hardware inspection:

pxe_ilo
iscsi_ilo
agent_ilo

Note

The RAID needs to be pre-configured prior to inspection otherwise proliantutils returns 0 for disk size.

The inspection process will discover the following essential properties (properties required for scheduling deployment):

memory_mb: memory size
cpus: number of cpus
cpu_arch: cpu architecture
local_gb: disk size

Inspection can also discover the following extra capabilities for iLO drivers:

ilo_firmware_version: iLO firmware version
rom_firmware_version: ROM firmware version
secure_boot: secure boot is supported or not. The possible values are 'true' or 'false'. The value is returned as 'true' if secure boot is supported by the server.
server_model: server model
pci_gpu_devices: number of gpu devices connected to the bare metal.
nic_capacity: the max speed of the embedded NIC adapter.
Note
- The capability nic_capacity can only be discovered if ipmitool version >= 1.8.15 is used on the conductor. The latest version can be downloaded from here.
- The iLO firmware version needs to be 2.10 or above for nic_capacity to be discovered.

The operator can specify these capabilities in nova flavor for node to be selected for scheduling:

nova flavor-key my-baremetal-flavor set capabilities:server_model="<in> Gen8"

nova flavor-key my-baremetal-flavor set capabilities:pci_gpu_devices="> 0"

nova flavor-key my-baremetal-flavor set capabilities:nic_capacity="10Gb"

nova flavor-key my-baremetal-flavor set capabilities:ilo_firmware_version="<in> 2.10"

nova flavor-key my-baremetal-flavor set capabilities:secure_boot="true"

Swiftless deploy for intermediate images

The iscsi_ilo and agent_ilo drivers can deploy and boot the server with and without swift being used for hosting the intermediate temporary floppy image (holding metadata for deploy kernel and ramdisk) and the boot ISO (which is required for iscsi_ilo only). A local HTTP(S) web server on each conductor node needs to be configured. Refer Web server configuration on conductor for more information. The HTTPS web server needs to be enabled (instead of HTTP web server) in order to send management information and images in encrypted channel over HTTPS.

Note

This feature assumes that the user inputs are on Glance which uses swift as backend. If swift dependency has to be eliminated, please refer to HTTP(S) Based Deploy Support also.

Deploy Process

Refer to Netboot in swiftless deploy for intermediate images for partition image support and refer to Localboot in swiftless deploy for intermediate images for whole disk image support.

HTTP(S) Based Deploy Support

The user input for the images given in driver_info like ilo_deploy_iso, deploy_kernel and deploy_ramdisk and in instance_info like image_source, kernel, ramdisk and ilo_boot_iso may also be given as HTTP(S) URLs.

The HTTP(S) web server can be configured in many ways. For the Apache web server on Ubuntu, refer here. The web server may reside on a different system than the conductor nodes, but its URL must be reachable by the conductor and the bare metal nodes.

Deploy Process

Refer to Netboot with HTTP(S) based deploy for partition image boot and refer to Localboot with HTTP(S) based deploy for whole disk image boot.

Support for iLO drivers with Standalone Ironic

It is possible to use ironic as standalone services without other OpenStack services. iLO drivers can be used in standalone ironic. This feature is referred to as iLO drivers with standalone ironic in this document and is supported by following drivers:

pxe_ilo
iscsi_ilo
agent_ilo

Configuration

The HTTP(S) web server needs to be configured as described in HTTP(S) Based Deploy Support and Web server configuration on conductor needs to be configured for hosting intermediate images on conductor as described in Swiftless deploy for intermediate images.

Deploy Process

iscsi_ilo supports both netboot and localboot, while agent_ilo supports only localboot. Refer to Netboot in standalone ironic and Localboot in standalone ironic for details of deploy process for netboot and localboot respectively. For pxe_ilo, the deploy process is same as native pxe_ipmitool driver.

Deploy Process

Activating iLO Advanced license as manual clean step

iLO drivers can activate the iLO Advanced license key as a manual cleaning step. Any manual cleaning step can only be initiated when a node is in the manageable state. Once the manual cleaning is finished, the node will be put in the manageable state again. User can follow steps from manual_cleaning to initiate manual cleaning operation on a node.

An example of a manual clean step to activate license as the only clean step could be:

'clean_steps': [{
    'interface': 'management',
    'step': 'activate_license',
    'args': {
        'ilo_license_key': 'ABC12-XXXXX-XXXXX-XXXXX-YZ345'
    }
}]

The different attributes of activate_license clean step are as follows:

Attribute Description

interface Interface of clean step, here management

step Name of clean step, here activate_license

args Keyword-argument entry (<name>: <value>) being passed to clean step

args.ilo_license_key The HPE iLO Advanced license key to activate enterprise features. This is mandatory.

Attribute	Description
`interface`	Interface of clean step, here `management`
`step`	Name of clean step, here `activate_license`
`args`	Keyword-argument entry (<name>: <value>) being passed to clean step
`args.ilo_license_key`	The HPE iLO Advanced license key to activate enterprise features. This is mandatory.
