iLO driver

iLO driver

Overview

iLO driver enables to take advantage of features of iLO management engine in HPE ProLiant servers. The ilo hardware type is targeted for HPE ProLiant Gen8 and Gen9 systems which have iLO 4 management engine. From Pike release ilo hardware type supports ProLiant Gen10 systems which have iLO 5 management engine. iLO5 conforms to Redfish API and hence hardware type redfish (see Redfish driver) is also an option for this kind of hardware but it lacks the iLO specific features.

For more details and for up-to-date information (like tested platforms, known issues, etc), please check the iLO driver wiki page.

For enabling Gen10 systems and getting detailed information on Gen10 feature support in Ironic please check this Gen10 wiki section.

Hardware type

ProLiant hardware is primarily supported by the ilo hardware type. This hardware can be used with reference hardware type ipmi (see IPMI driver) and redfish (see Redfish driver). For information on how to enable the ilo hardware type, see Enabling hardware types.

Note

Only HPE ProLiant Gen10 servers supports hardware type redfish.

The hardware type ilo supports following HPE server features:

Hardware interfaces

The ilo hardware type supports following hardware interfaces:

  • bios

    Supports ilo and no-bios. The default is ilo. They can be enabled by using the [DEFAULT]enabled_bios_interfaces option in ironic.conf as given below:

    [DEFAULT]
    enabled_hardware_types = ilo
    enabled_bios_interfaces = ilo,no-bios
    
  • boot

    Supports ilo-virtual-media and ilo-pxe. The default is ilo-virtual-media. The ilo-virtual-media interface provides security enhanced PXE-less deployment by using iLO virtual media to boot up the bare metal node. The ilo-pxe interface uses PXE/iSCSI for deployment(just like PXE boot). This interface doesn’t require iLO Advanced license. They can be enabled by using the [DEFAULT]enabled_boot_interfaces option in ironic.conf as given below:

    [DEFAULT]
    enabled_hardware_types = ilo
    enabled_boot_interfaces = ilo-virtual-media,ilo-pxe
    
  • console

    Supports ilo and no-console. The default is ilo. They can be enabled by using the [DEFAULT]enabled_console_interfaces option in ironic.conf as given below:

    [DEFAULT]
    enabled_hardware_types = ilo
    enabled_console_interfaces = ilo,no-console
    

    Note

    To use ilo console interface you need to enable iLO feature ‘IPMI/DCMI over LAN Access’ on iLO4 and iLO5 management engine.

  • inspect

    Supports ilo and inspector. The default is ilo. They can be enabled by using the [DEFAULT]enabled_inspect_interfaces option in ironic.conf as given below:

    [DEFAULT]
    enabled_hardware_types = ilo
    enabled_inspect_interfaces = ilo,inspector
    

    Note

    Ironic Inspector needs to be configured to use inspector as the inspect interface.

  • management

    Supports only ilo. It can be enabled by using the [DEFAULT]enabled_management_interfaces option in ironic.conf as given below:

    [DEFAULT]
    enabled_hardware_types = ilo
    enabled_management_interfaces = ilo
    
  • power

    Supports only ilo. It can be enabled by using the [DEFAULT]enabled_power_interfaces option in ironic.conf as given below:

    [DEFAULT]
    enabled_hardware_types = ilo
    enabled_power_interfaces = ilo
    
  • raid

    Supports agent and no-raid. The default is no-raid. They can be enabled by using the [DEFAULT]enabled_raid_interfaces option in ironic.conf as given below:

    [DEFAULT]
    enabled_hardware_types = ilo
    enabled_raid_interfaces = agent,no-raid
    
  • storage

    Supports cinder and noop. The default is noop. They can be enabled by using the [DEFAULT]enabled_storage_interfaces option in ironic.conf as given below:

    [DEFAULT]
    enabled_hardware_types = ilo
    enabled_storage_interfaces = cinder,noop
    

    Note

    The storage interface cinder is supported only when corresponding boot interface of the ilo hardware type based node is ilo-pxe. Please refer to Boot From Volume for configuring cinder as a storage interface.

  • rescue

    Supports agent and no-rescue. The default is no-rescue. They can be enabled by using the [DEFAULT]enabled_rescue_interfaces option in ironic.conf as given below:

    [DEFAULT]
    enabled_hardware_types = ilo
    enabled_rescue_interfaces = agent,no-rescue
    

ilo hardware type supports all standard deploy and network interface implementations, see Enabling hardware interfaces for details.

The following command can be used to enroll a ProLiant node with ilo hardware type:

openstack baremetal node create --os-baremetal-api-version=1.38 \
    --driver ilo \
    --deploy-interface direct \
    --raid-interface agent \
    --rescue-interface agent \
    --driver-info ilo_address=<ilo-ip-address> \
    --driver-info ilo_username=<ilo-username> \
    --driver-info ilo_password=<ilo-password> \
    --driver-info ilo_deploy_iso=<glance-uuid-of-deploy-iso> \
    --driver-info ilo_rescue_iso=<glance-uuid-of-rescue-iso>

Please refer to Enabling drivers and hardware types for detailed explanation of hardware type.

Node configuration

  • Each node is configured for ilo hardware type by setting the following ironic node object’s properties 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.
    • 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.
    • ca_file: (optional) CA certificate file to validate iLO.
    • console_port: (optional) Node’s UDP port for console access. Any unused port on the ironic conductor node may be used. This is required only when ilo-console interface is used.

    • ilo_deploy_iso: The glance UUID of the deploy ramdisk ISO image.

    • instance info/ilo_boot_iso property to be either boot iso Glance UUID or a HTTP(S) URL. This is optional property and is used when boot_option is set to netboot or ramdisk.

      Note

      When boot_option is set to ramdisk, the ironic node must be configured to use ramdisk deploy interface. See Ramdisk deploy for details.

    • ilo_rescue_iso: The glance UUID of the rescue ISO image. This is optional property and is used when rescue interface is set to agent.

  • The following properties are also required in node object’s driver_info if ilo-pxe boot interface is used:

    • deploy_kernel: The glance UUID or a HTTP(S) URL of the deployment kernel.
    • deploy_ramdisk: The glance UUID or a HTTP(S) URL of the deployment ramdisk.

    • snmp_auth_priv_protocol : The Privacy protocol. The valid values are “AES” and “DES”. The iLO default value is “DES”.

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.

Prerequisites

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

    Install proliantutils module on the ironic conductor node. Minimum version required is 2.5.0:

    $ pip install "proliantutils>=2.5.0"
    
  • 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. Please refer to Hardware Inspection Support for more information on recommended version.

Different configuration for ilo hardware type

Glance Configuration

  1. Configure Glance image service with its storage backend as Swift.

  2. 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
    
  3. 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
    
  4. 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
    
  5. 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, the ilo-virtual-media boot interface uses swift containers to host the intermediate floppy image and the boot ISO. If the variable is set to true, it 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 ilo-virtual-media boot interface will send the instance’s configdrive over an encrypted channel if web server is HTTPS enabled.

Enable driver

  1. Build a deploy ISO (and kernel and ramdisk) image, see Building or downloading a deploy ramdisk image

  2. See Glance Configuration for configuring glance image service with its storage backend as swift.

  3. Upload this image to Glance:

    glance image-create --name deploy-ramdisk.iso --disk-format iso --container-format bare < deploy-ramdisk.iso
    
  4. Enable hardware type and hardware interfaces in /etc/ironic/ironic.conf:

    [DEFAULT]
    enabled_hardware_types = ilo
    enabled_bios_interfaces = ilo
    enabled_boot_interfaces = ilo-virtual-media,ilo-pxe
    enabled_power_interfaces = ilo
    enabled_console_interfaces = ilo
    enabled_raid_interfaces = agent
    enabled_management_interfaces = ilo
    enabled_inspect_interfaces = ilo
    enabled_rescue_interfaces = agent
    
  5. Restart the ironic conductor service:

    $ service ironic-conductor restart
    

Optional functionalities for the ilo hardware type

Boot mode support

The hardware type ilo supports automatic detection and setting of boot mode (Legacy BIOS or UEFI).

  • 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 driver uses that boot mode for provisioning the baremetal ProLiant servers.
    • If the pending boot mode is set on the node then iLO driver uses that boot mode for provisioning the baremetal ProLiant servers.
    • If the pending boot mode is not set on the node then iLO driver uses ‘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:

    openstack baremetal node set <node-uuid> --property 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 hardware type ilo supports secure boot deploy.

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:

openstack baremetal node set <node-uuid> --property 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. Please refer to 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 the ilo-virtual-media boot interface, 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 hardware type ilo supports node cleaning.

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.
    • erase_devices: An inband clean step that performs disk erase on all the disks including the disks visible to OS as well as the raw disks visible to Smart Storage Administrator (SSA). This step supports erasing of the raw disks visible to SSA in Proliant servers only with the ramdisk created using diskimage-builder from Ocata release. By default, this step is disabled. See Disk Erase Support for more details.
  • For supported in-band cleaning operations, 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] and [deploy] section in ironic.conf

    [ilo]
    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
    
    [deploy]
    erase_devices_priority=0
    

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 the ilo-virtual-media boot interface as it needs 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 the driver 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 and chassis. Please 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).

    update_firmware_sum:

    Updates all or list of user specified firmware components on the node using Smart Update Manager (SUM). It is an inband step associated with the management interface. See Smart Update Manager (SUM) based firmware update for more information on usage.

  • 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 hardware type ilo supports hardware inspection.

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. Pleae 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 size
  • cpus: number of cpus
  • cpu_arch: cpu architecture
  • local_gb: disk size

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

  • 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.

  • sriov_enabled: true, if server has the SRIOV supporting NIC.

  • has_rotational: true, if server has HDD disk.

  • has_ssd: true, if server has SSD disk.

  • has_nvme_ssd: true, if server has NVME SSD disk.

  • cpu_vt: true, if server supports cpu virtualization.

  • hardware_supports_raid: true, if RAID can be configured on the server using RAID controller.

  • nvdimm_n: true, if server has NVDIMM_N type of persistent memory.

  • persistent_memory: true, if server has persistent memory.

  • logical_nvdimm_n: true, if server has logical NVDIMM_N configured.

  • rotational_drive_<speed>_rpm: The capabilities rotational_drive_4800_rpm, rotational_drive_5400_rpm, rotational_drive_7200_rpm, rotational_drive_10000_rpm and rotational_drive_15000_rpm are set to true if the server has HDD drives with speed of 4800, 5400, 7200, 10000 and 15000 rpm respectively.

  • logical_raid_level_<raid_level>: The capabilities logical_raid_level_0, logical_raid_level_1, logical_raid_level_2, logical_raid_level_5, logical_raid_level_6, logical_raid_level_10, logical_raid_level_50 and logical_raid_level_60 are set to true if any of the raid levels among 0, 1, 2, 5, 6, 10, 50 and 60 are configured on the system.

    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.
    • To discover IPMI based attributes you need to enable iLO feature ‘IPMI/DCMI over LAN Access’ on iLO4 and iLO5 management engine.

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"

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

See Capabilities discovery for more details and examples.

Swiftless deploy for intermediate images

The hardware type ilo with ilo-virtual-media as boot interface 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. A local HTTP(S) web server on each conductor node needs to be configured. Please refer to 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

Please refer to Netboot in swiftless deploy for intermediate images for partition image support and 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

Activating iLO Advanced license as manual clean step

iLO driver 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 driver 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 and swift.

    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 driver uses 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 and chassis.

  • 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 aborted firmware_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
    

Smart Update Manager (SUM) based firmware update

The firmware update based on SUM is an inband clean step supported by iLO driver. The firmware update is performed on all or list of user specified firmware components on the node. Refer to SUM User Guide to get more information on SUM based firmware update.

update_firmware_sum clean step requires the agent ramdisk with Proliant Hardware Manager from the proliantutils version 2.5.0 or higher. See DIB support for Proliant Hardware Manager to create the agent ramdisk with Proliant Hardware Manager.

The attributes of update_firmware_sum clean step are as follows:

Attribute Description
interface Interface of the clean step, here management
step Name of the clean step, here update_firmware_sum
args Keyword-argument entry (<name>: <value>) being passed to the clean step

The keyword arguments used for the clean step are as follows:

  • url: URL of SPP (Service Pack for Proliant) ISO. It is mandatory. The URL schemes supported are http, https and swift.
  • checksum: MD5 checksum of SPP ISO to verify the image. It is mandatory.
  • components: List of filenames of the firmware components to be flashed. It is optional. If not provided, the firmware update is performed on all the firmware components.

The clean step performs an update on all or a list of firmware components and returns the SUM log files. The log files include hpsum_log.txt and hpsum_detail_log.txt which holds the information about firmware components, firmware version for each component and their update status. The log object will be named with the following pattern:

<node-uuid>[_<instance-uuid>]_update_firmware_sum_<timestamp yyyy-mm-dd-hh-mm-ss>.tar.gz

Refer to Retrieving logs from the deploy ramdisk for more information on enabling and viewing the logs returned from the ramdisk.

An example of update_firmware_sum clean step:

{
    "interface": "management",
    "step": "update_firmware_sum",
    "args":
        {
            "url": "http://my_address:port/SPP.iso",
            "checksum": "abcdefxyz",
            "components": ["CP024356.scexe", "CP008097.exe"]
        }
}

The clean step fails if there is any error in the processing of clean step arguments. The processing error could happen during validation of components’ file extension, image download, image checksum verification or image extraction. In case of a failure, check Ironic conductor logs carefully to see if there are any validation or firmware processing related errors which may help in root cause analysis or gaining an understanding of where things were left off or where things failed. You can then fix or work around and then try again.

Warning

This feature is officially supported only with RHEL and SUSE based IPA ramdisk. Refer to SUM for supported OS versions for specific SUM version.

Note

Refer Guidelines for SPP ISO for steps to get SPP (Service Pack for ProLiant) ISO.

RAID Support

The inband RAID functionality is supported by iLO driver. 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 with wwn details of root volume. It is used by iLO driver as root device hint during provisioning.

  • The value of raid level of root volume is added as raid_level capability to the node’s capabilities parameter within properties field. The operator can specify the raid_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

Disk Erase Support

erase_devices is an inband clean step supported by iLO driver. It performs erase on all the disks including the disks visible to OS as well as the raw disks visible to the Smart Storage Administrator (SSA).

This inband clean step requires ssacli utility starting from version 2.60-19.0 to perform the erase on physical disks. See the ssacli documentation for more information on ssacli utility and different erase methods supported by SSA.

The disk erasure via shred is used to erase disks visible to the OS and its implementation is available in Ironic Python Agent. The raw disks connected to the Smart Storage Controller are erased using Sanitize erase which is a ssacli supported erase method. If Sanitize erase is not supported on the Smart Storage Controller the disks are erased using One-pass erase (overwrite with zeros).

This clean step is supported when the agent ramdisk contains the Proliant Hardware Manager from the proliantutils version 2.3.0 or higher. This clean step is performed as part of automated cleaning and it is disabled by default. See In-band vs out-of-band for more information on enabling/disabling a clean step.

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

See the proliant-tools for more information on creating agent ramdisk with proliant-tools element in DIB.

Firmware based UEFI iSCSI boot from volume support

With Gen9 (UEFI firmware version 1.40 or higher) and Gen10 HPE Proliant servers, the driver supports firmware based UEFI boot of an iSCSI cinder volume.

This feature requires the node to be configured to boot in UEFI boot mode, as well as user image should be UEFI bootable image, and PortFast needs to be enabled in switch configuration for immediate spanning tree forwarding state so it wouldn’t take much time setting the iSCSI target as persistent device.

The driver does not support this functionality when in bios boot mode. In case the node is configured with ilo-pxe boot interface and the boot mode configured on the bare metal is bios, the iscsi boot from volume is performed using ipxe. See Boot From Volume for more details.

To use this feature, configure the boot mode of the bare metal to uefi and configure the corresponding ironic node using the steps given in Boot From Volume. In a cloud environment with nodes configured to boot from bios and uefi boot modes, the virtual media driver only supports uefi boot mode, and that attempting to use iscsi boot at the same time with a bios volume will result in an error.

BIOS configuration support

The ilo hardware type supports ilo BIOS interface. The support includes providing manual clean steps apply_configuration and factory_reset to manage supported BIOS settings on the node. See BIOS Configuration for more details and examples.

Note

The change in the settings will take into effect after next power cycle.

Certificate based validation in iLO

The driver supports validation of certificates on the HPE Proliant servers. The path to certificate file needs to be appropriately set in ca_file in the node’s driver_info. To update SSL certificates into iLO, refer to HPE Integrated Lights-Out Security Technology Brief. 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.

Rescue mode support

The hardware type ilo supports rescue functionality. Rescue operation can be used to boot nodes into a rescue ramdisk so that the rescue user can access the node.

Please refer to Rescue Mode for detailed explanation of rescue feature.

Inject NMI support

The management interface ilo supports injection of non-maskable interrupt (NMI) to a bare metal. Following command can be used to inject NMI on a server:

openstack baremetal node inject nmi <node>

Following command can be used to inject NMI via Compute service:

openstack server dump create <server>

Note

This feature is supported on HPE ProLiant Gen9 servers and beyond.

Soft power operation support

The power interface ilo supports soft power off and soft reboot operations on a bare metal. Following commands can be used to perform soft power operations on a server:

openstack baremetal node reboot --soft \
    [--power-timeout <power-timeout>] <node>

openstack baremetal node power off --soft \
    [--power-timeout <power-timeout>] <node>

Note

The configuration [conductor]soft_power_off_timeout is used as a default timeout value when no timeout is provided while invoking hard or soft power operations.

Note

Server POST state is used to track the power status of HPE ProLiant Gen9 servers and beyond.
