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 supports both net-boot
and local-boot of instance.
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 2.2.0:$ pip install "proliantutils>=2.2.0"
ipmitool
command must be present on the service node(s) whereironic-conductor
is running. On most distros, this is provided as part of theipmitool
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 asservice
, 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
inkeystone_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
andhttp_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 Building or downloading a deploy ramdisk image
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
andpxe_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 and glance have HTTPS endpoints (See Enabling HTTPS in Swift, Enabling HTTPS in Image service for more information), the
iscsi_ilo
driver provides enhanced security by exchanging management information with swift and glance endpoints 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 Gen7 Servers with iLO 3, Gen8 Servers and above with iLO 4. It has been tested with the following servers:
- ProLiant DL380 G7
- ProLiant DL380e Gen8
- ProLiant DL580 Gen8 UEFI
- ProLiant DL180 Gen9 UEFI
- ProLiant DL360 Gen9 UEFI
- ProLiant DL380 Gen9 UEFI
- ProLiant XL450 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 and glance have HTTPS endpoints. See Enabling HTTPS in Swift, Enabling HTTPS in Image service for more information. 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.
- Supports both out-of-band and in-band cleaning operations. For more details, see In-band vs out-of-band.
- 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 and Localboot with glance and swift for partition images 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.ca_file
: (optional) CA certificate file to validate iLO.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.
Note
To update SSL certificates into iLO, you can refer to HPE Integrated Lights-Out Security Technology Brief. You can use iLO hostname or IP address as a ‘Common Name (CN)’ while generating Certificate Signing Request (CSR). Use the same value as ilo_address while enrolling node to Bare Metal service to avoid SSL certificate validation errors related to hostname mismatch.
Note
If configuration values for ca_file
, client_port
and
client_timeout
are not provided in the driver_info
of the node,
the corresponding config variables defined under [ilo]
section in
ironic.conf will 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>

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 config variable
default_boot_mode
in[ilo]
section of ironic configuration file is set to either ‘bios’ or ‘uefi’, then iLO drivers use that boot mode for provisioning the baremetal ProLiant servers. - 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.
- If config variable
When boot mode capability is configured, the driver sets the pending boot mode to the configured value.
Only one boot mode (either
uefi
orbios
) can be configured for the node.If the operator wants a node to boot always in
uefi
mode orbios
mode, then they may usecapabilities
parameter withinproperties
field of an ironic node.To configure a node in
uefi
mode, then setcapabilities
as below:ironic node-update <node-uuid> add properties/capabilities='boot_mode:uefi'
Nodes having
boot_mode
set touefi
may be requested by adding anextra_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 inextra_spec
as above, nova scheduler (ComputeCapabilitiesFilter
) will match only ironic nodes which have theboot_mode
set appropriately inproperties/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
andbios
machines, and operator wants to provide a choice to the user regarding boot modes. If the flavor doesn’t containboot_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 Building or downloading a deploy ramdisk image 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.

Node Cleaning Support¶
The following iLO drivers support node cleaning -
pxe_ilo
iscsi_ilo
agent_ilo
For more information on node cleaning, see Node 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 10. 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 In-band vs out-of-band.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
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 the
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 likeiscsi_ilo
andagent_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.update_firmware
:Updates the firmware of the devices. Also an out-of-band step associated with the
management
interface. See Initiating firmware update as manual clean step for user guidance on usage. The supported devices for firmware update are:ilo
,cpld
,power_pic
,bios
andchassis
. Refer to below table for their commonly used descriptions.Device Description ilo
BMC for HPE ProLiant servers cpld
System programmable logic device power_pic
Power management controller bios
HPE ProLiant System ROM chassis
System chassis device Some devices firmware cannot be updated via this method, such as: storage controllers, host bus adapters, disk drive firmware, network interfaces and Onboard Administrator (OA).
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 disk size is returned by RIBCL/RIS only when RAID is preconfigured on the storage. If the storage is Direct Attached Storage, then RIBCL/RIS fails to get the disk size.
The SNMPv3 inspection gets disk size for all types of storages. If RIBCL/RIS is unable to get disk size and SNMPv3 inspection is requested, the proliantutils does SNMPv3 inspection to get the disk size. If proliantutils is unable to get the disk size, it raises an error. This feature is available in proliantutils release version >= 2.2.0.
The iLO must be updated with SNMPv3 authentication details. Refer to the section SNMPv3 Authentication in HPE iLO4 User Guide for setting up authentication details on iLO. The following parameters are mandatory to be given in driver_info for SNMPv3 inspection:
snmp_auth_user
: The SNMPv3 user.snmp_auth_prot_password
: The auth protocol pass phrase.snmp_auth_priv_password
: The privacy protocol pass phrase.
The following parameters are optional for SNMPv3 inspection:
snmp_auth_protocol
: The Auth Protocol. The valid values are “MD5” and “SHA”. The iLO default value is “MD5”.snmp_auth_priv_protocol
: The Privacy protocol. The valid values are “AES” and “DES”. The iLO default value is “DES”.
The inspection process will discover the following essential properties (properties required for scheduling deployment):
memory_mb
: memory sizecpus
: number of cpuscpu_arch
: cpu architecturelocal_gb
: disk size
Inspection can also discover the following extra capabilities for iLO drivers:
ilo_firmware_version
: iLO firmware versionrom_firmware_version
: ROM firmware versionsecure_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 modelpci_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 capability
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:nic_capacity="10Gb"
nova flavor-key my-baremetal-flavor set capabilities:ilo_firmware_version="<in> 2.10"
See Capabilities discovery for more details and examples.
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
and agent_ilo
supports both netboot and 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.

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 with 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
iLO Advanced license key to activate enterprise features. This is mandatory.
Initiating firmware update as manual clean step¶
iLO drivers can invoke secure firmware update 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. A user can follow steps from Manual cleaning
to initiate manual cleaning operation on a node.
An example of a manual clean step with update_firmware
as the only clean
step could be:
"clean_steps": [{
"interface": "management",
"step": "update_firmware",
"args": {
"firmware_update_mode": "ilo",
"firmware_images":[
{
"url": "file:///firmware_images/ilo/1.5/CP024444.scexe",
"checksum": "a94e683ea16d9ae44768f0a65942234d",
"component": "ilo"
},
{
"url": "swift://firmware_container/cpld2.3.rpm",
"checksum": "<md5-checksum-of-this-file>",
"component": "cpld"
},
{
"url": "http://my_address:port/firmwares/bios_vLatest.scexe",
"checksum": "<md5-checksum-of-this-file>",
"component": "bios"
},
{
"url": "https://my_secure_address_url/firmwares/chassis_vLatest.scexe",
"checksum": "<md5-checksum-of-this-file>",
"component": "chassis"
},
{
"url": "file:///home/ubuntu/firmware_images/power_pic/pmc_v3.0.bin",
"checksum": "<md5-checksum-of-this-file>",
"component": "power_pic"
}
]
}
}]
The different attributes of update_firmware
clean step are as follows:
Attribute Description interface
Interface of clean step, here management
step
Name of clean step, here update_firmware
args
Keyword-argument entry (<name>: <value>) being passed to clean step args.firmware_update_mode
Mode (or mechanism) of out-of-band firmware update. Supported value is ilo
. This is mandatory.args.firmware_images
Ordered list of dictionaries of images to be flashed. This is mandatory.
Each firmware image block is represented by a dictionary (JSON), in the form:
{
"url": "<url of firmware image file>",
"checksum": "<md5 checksum of firmware image file to verify the image>",
"component": "<device on which firmware image will be flashed>"
}
All the fields in the firmware image block are mandatory.
- The different types of firmware url schemes supported are:
file
,http
,https
andswift
.
Note
This feature assumes that while using file
url scheme the file path is
on the conductor controlling the node.
Note
The swift
url scheme assumes the swift account of the service
project. The service
project (tenant) is a special project created in
the Keystone system designed for the use of the core OpenStack services.
When Ironic makes use of Swift for storage purpose, the account is generally
service
and the container is generally ironic
and ilo
drivers
use a container named ironic_ilo_container
for their own purpose.
Note
While using firmware files with a .rpm
extension, make sure the commands
rpm2cpio
and cpio
are present on the conductor, as they are utilized
to extract the firmware image from the package.
The firmware components that can be updated are:
ilo
,cpld
,power_pic
,bios
andchassis
.The firmware images will be updated in the order given by the operator. If there is any error during processing of any of the given firmware images provided in the list, none of the firmware updates will occur. The processing error could happen during image download, image checksum verification or image extraction. The logic is to process each of the firmware files and update them on the devices only if all the files are processed successfully. If, during the update (uploading and flashing) process, an update fails, then the remaining updates, if any, in the list will be aborted. But it is recommended to triage and fix the failure and re-attempt the manual clean step
update_firmware
for the abortedfirmware_images
.The devices for which the firmwares have been updated successfully would start functioning using their newly updated firmware.
As a troubleshooting guidance on the complete process, check Ironic conductor logs carefully to see if there are any firmware processing or update related errors which may help in root causing or gain an understanding of where things were left off or where things failed. You can then fix or work around and then try again. A common cause of update failure is HPE Secure Digital Signature check failure for the firmware image file.
To compute
md5
checksum for your image file, you can use the following command:$ md5sum image.rpm 66cdb090c80b71daa21a67f06ecd3f33 image.rpm
RAID Support¶
The inband RAID functionality is supported by iLO drivers. See RAID Configuration for more information. Bare Metal service update node with following information after successful configuration of RAID:
Node
properties/local_gb
is set to the size of root volume.Node
properties/root_device
is filled withwwn
details of root volume. It is used by iLO drivers as root device hint during provisioning.The value of raid level of root volume is added as
raid_level
capability to the node’scapabilities
parameter withinproperties
field. The operator can specify theraid_level
capability in nova flavor for node to be selected for scheduling:nova flavor-key ironic-test set capabilities:raid_level="1+0" nova boot --flavor ironic-test --image test-image instance-1
DIB support for Proliant Hardware Manager¶
To create an agent ramdisk with Proliant Hardware Manager
,
use the proliant-tools
element in DIB:
disk-image-create -o proliant-agent-ramdisk ironic-agent fedora proliant-tools
