Chapter 3. Bare-metal configuration When deploying OpenShift Container Platform on bare-metal hosts, there are times when you need to make changes to the host either before or after provisioning. This can include inspecting the host's hardware, firmware, and firmware details. It can also include formatting disks or changing modifiable firmware settings. 3.1. Services for a user-managed load balancer You can configure an OpenShift Container Platform cluster to use a user-managed load balancer in place of the default load balancer. Important Configuring a user-managed load balancer depends on your vendor's load balancer. The information and examples in this section are for guideline purposes only. Consult the vendor documentation for more specific information about the vendor's load balancer. Red Hat supports the following services for a user-managed load balancer: Ingress Controller OpenShift API OpenShift MachineConfig API You can choose whether you want to configure one or all of these services for a user-managed load balancer. Configuring only the Ingress Controller service is a common configuration option. To better understand each service, view the following diagrams: Figure 3.1. Example network workflow that shows an Ingress Controller operating in an OpenShift Container Platform environment Figure 3.2. Example network workflow that shows an OpenShift API operating in an OpenShift Container Platform environment Figure 3.3. Example network workflow that shows an OpenShift MachineConfig API operating in an OpenShift Container Platform environment The following configuration options are supported for user-managed load balancers: Use a node selector to map the Ingress Controller to a specific set of nodes. You must assign a static IP address to each node in this set, or configure each node to receive the same IP address from the Dynamic Host Configuration Protocol (DHCP). Infrastructure nodes commonly receive this type of configuration. Target all IP addresses on a subnet. This configuration can reduce maintenance overhead, because you can create and destroy nodes within those networks without reconfiguring the load balancer targets. If you deploy your ingress pods by using a machine set on a smaller network, such as a /27 or /28 , you can simplify your load balancer targets. Tip You can list all IP addresses that exist in a network by checking the machine config pool's resources. Before you configure a user-managed load balancer for your OpenShift Container Platform cluster, consider the following information: For a front-end IP address, you can use the same IP address for the front-end IP address, the Ingress Controller's load balancer, and API load balancer. Check the vendor's documentation for this capability. For a back-end IP address, ensure that an IP address for an OpenShift Container Platform control plane node does not change during the lifetime of the user-managed load balancer. You can achieve this by completing one of the following actions: Assign a static IP address to each control plane node. Configure each node to receive the same IP address from the DHCP every time the node requests a DHCP lease. Depending on the vendor, the DHCP lease might be in the form of an IP reservation or a static DHCP assignment. Manually define each node that runs the Ingress Controller in the user-managed load balancer for the Ingress Controller back-end service. For example, if the Ingress Controller moves to an undefined node, a connection outage can occur. 3.1.1. Configuring a user-managed load balancer You can configure an OpenShift Container Platform cluster to use a user-managed load balancer in place of the default load balancer. Important Before you configure a user-managed load balancer, ensure that you read the "Services for a user-managed load balancer" section. Read the following prerequisites that apply to the service that you want to configure for your user-managed load balancer. Note MetalLB, which runs on a cluster, functions as a user-managed load balancer. OpenShift API prerequisites You defined a front-end IP address. TCP ports 6443 and 22623 are exposed on the front-end IP address of your load balancer. Check the following items: Port 6443 provides access to the OpenShift API service. Port 22623 can provide ignition startup configurations to nodes. The front-end IP address and port 6443 are reachable by all users of your system with a location external to your OpenShift Container Platform cluster. The front-end IP address and port 22623 are reachable only by OpenShift Container Platform nodes. The load balancer backend can communicate with OpenShift Container Platform control plane nodes on port 6443 and 22623. Ingress Controller prerequisites You defined a front-end IP address. TCP ports 443 and 80 are exposed on the front-end IP address of your load balancer. The front-end IP address, port 80 and port 443 are be reachable by all users of your system with a location external to your OpenShift Container Platform cluster. The front-end IP address, port 80 and port 443 are reachable to all nodes that operate in your OpenShift Container Platform cluster. The load balancer backend can communicate with OpenShift Container Platform nodes that run the Ingress Controller on ports 80, 443, and 1936. Prerequisite for health check URL specifications You can configure most load balancers by setting health check URLs that determine if a service is available or unavailable. OpenShift Container Platform provides these health checks for the OpenShift API, Machine Configuration API, and Ingress Controller backend services. The following examples show health check specifications for the previously listed backend services: Example of a Kubernetes API health check specification Path: HTTPS:6443/readyz Healthy threshold: 2 Unhealthy threshold: 2 Timeout: 10 Interval: 10 Example of a Machine Config API health check specification Path: HTTPS:22623/healthz Healthy threshold: 2 Unhealthy threshold: 2 Timeout: 10 Interval: 10 Example of an Ingress Controller health check specification Path: HTTP:1936/healthz/ready Healthy threshold: 2 Unhealthy threshold: 2 Timeout: 5 Interval: 10 Procedure Configure the HAProxy Ingress Controller, so that you can enable access to the cluster from your load balancer on ports 6443, 22623, 443, and 80. Depending on your needs, you can specify the IP address of a single subnet or IP addresses from multiple subnets in your HAProxy configuration.

You must update records to your DNS server for the cluster API and applications over the load balancer. Examples of modified DNS records <load_balancer_ip_address> A api.<cluster_name>.<base_domain> A record pointing to Load Balancer Front End <load_balancer_ip_address> A apps.<cluster_name>.<base_domain> A record pointing to Load Balancer Front End Important DNS propagation might take some time for each DNS record to become available. Ensure that each DNS record propagates before validating each record. For your OpenShift Container Platform cluster to use the user-managed load balancer, you must specify the following configuration in your cluster's install-config.yaml file: # ... platform: loadBalancer: type: UserManaged 1 apiVIPs: - <api_ip> 2 ingressVIPs: - <ingress_ip> 3 # ... 1 Set UserManaged for the type parameter to specify a user-managed load balancer for your cluster. The parameter defaults to OpenShiftManagedDefault , which denotes the default internal load balancer. For services defined in an openshift-kni-infra namespace, a user-managed load balancer can deploy the coredns service to pods in your cluster but ignores keepalived and haproxy services. 2 Required parameter when you specify a user-managed load balancer. Specify the user-managed load balancer's public IP address, so that the Kubernetes API can communicate with the user-managed load balancer. 3 Required parameter when you specify a user-managed load balancer.

About the Bare Metal Operator Use the Bare Metal Operator (BMO) to provision, manage, and inspect bare-metal hosts in your cluster. The BMO uses the following resources to complete these tasks: BareMetalHost HostFirmwareSettings FirmwareSchema HostFirmwareComponents The BMO maintains an inventory of the physical hosts in the cluster by mapping each bare-metal host to an instance of the BareMetalHost custom resource definition. Each BareMetalHost resource features hardware, software, and firmware details. The BMO continually inspects the bare-metal hosts in the cluster to ensure each BareMetalHost resource accurately details the components of the corresponding host. The BMO also uses the HostFirmwareSettings resource, the FirmwareSchema resource, and the HostFirmwareComponents resource to detail firmware specifications and upgrade or downgrade firmware for the bare-metal host. The BMO interfaces with bare-metal hosts in the cluster by using the Ironic API service. The Ironic service uses the Baseboard Management Controller (BMC) on the host to interface with the machine. Some common tasks you can complete by using the BMO include the following: Provision bare-metal hosts to the cluster with a specific image Format a host's disk contents before provisioning or after deprovisioning Turn on or off a host Change firmware settings View the host's hardware details Upgrade or downgrade a host's firmware to a specific version 3.2.1. Bare Metal Operator architecture The Bare Metal Operator (BMO) uses the following resources to provision, manage, and inspect bare-metal hosts in your cluster. The following diagram illustrates the architecture of these resources: BareMetalHost The BareMetalHost resource defines a physical host and its properties. When you provision a bare-metal host to the cluster, you must define a BareMetalHost resource for that host. For ongoing management of the host, you can inspect the information in the BareMetalHost or update this information. The BareMetalHost resource features provisioning information such as the following: Deployment specifications such as the operating system boot image or the custom RAM disk Provisioning state Baseboard Management Controller (BMC) address Desired power state The BareMetalHost resource features hardware information such as the following: Number of CPUs MAC address of a NIC Size of the host's storage device Current power state HostFirmwareSettings You can use the HostFirmwareSettings resource to retrieve and manage the firmware settings for a host. When a host moves to the Available state, the Ironic service reads the host's firmware settings and creates the HostFirmwareSettings resource. There is a one-to-one mapping between the BareMetalHost resource and the HostFirmwareSettings resource. You can use the HostFirmwareSettings resource to inspect the firmware specifications for a host or to update a host's firmware specifications. Note You must adhere to the schema specific to the vendor firmware when you edit the spec field of the HostFirmwareSettings resource. This schema is defined in the read-only FirmwareSchema resource. FirmwareSchema Firmware settings vary among hardware vendors and host models. A FirmwareSchema resource is a read-only resource that contains the types and limits for each firmware setting on each host model. The data comes directly from the BMC by using the Ironic service. The FirmwareSchema resource enables you to identify valid values you can specify in the spec field of the HostFirmwareSettings resource. A FirmwareSchema resource can apply to many BareMetalHost resources if the schema is the same. HostFirmwareComponents Metal 3 provides the HostFirmwareComponents resource, which describes BIOS and baseboard management controller (BMC) firmware versions. You can upgrade or downgrade the host's firmware to a specific version by editing the spec field of the HostFirmwareComponents resource. This is useful when deploying with validated patterns that have been tested against specific firmware versions. Additional resources Metal 3 API service for provisioning bare-metal hosts Ironic API service for managing bare-metal infrastructure 3.3. Creating a manifest object that includes a customized br-ex bridge As an alternative to using the configure-ovs.sh shell script to set a br-ex bridge on a bare-metal platform, you can create a NodeNetworkConfigurationPolicy custom resource (CR) that includes an NMState configuration file. The NMState configuration file creates a customized br-ex bridge network configuration on each node in your cluster. This feature supports the following tasks: Modifying the maximum transmission unit (MTU) for your cluster. Modifying attributes of a different bond interface, such as MIImon (Media Independent Interface Monitor), bonding mode, or Quality of Service (QoS). Updating DNS values. Consider the following use cases for creating a manifest object that includes a customized br-ex bridge: You want to make postinstallation changes to the bridge, such as changing the Open vSwitch (OVS) or OVN-Kubernetes br-ex bridge network. The configure-ovs.sh shell script does not support making postinstallation changes to the bridge. You want to deploy the bridge on a different interface than the interface available on a host or server IP address. You want to make advanced configurations to the bridge that are not possible with the configure-ovs.sh shell script. Using the script for these configurations might result in the bridge failing to connect multiple network interfaces and facilitating data forwarding between the interfaces. Prerequisites You set a customized br-ex by using the alternative method to configure-ovs . You installed the Kubernetes NMState Operator. Procedure Create a NodeNetworkConfigurationPolicy (NNCP) CR and define a customized br-ex bridge network configuration. Depending on your needs, ensure that you set a masquerade IP for either the ipv4.address.ip , ipv6.address.ip , or both parameters. A masquerade IP address must match an in-use IP address block. Important As a post-installation task, you can configure most parameters for a customized br-ex bridge that you defined in an existing NNCP CR, except for the IP address. Example of an NNCP CR that sets IPv6 and IPv4 masquerade IP addresses apiVersion: nmstate.io/v1 kind: NodeNetworkConfigurationPolicy metadata: name: worker-0-br-ex 1 spec: nodeSelector: kubernetes.io/hostname: worker-0 desiredState: interfaces: - name: enp2s0 2 type: ethernet 3 state: up 4 ipv4: enabled: false 5 ipv6: enabled: false - name: br-ex type: ovs-bridge state: up ipv4: enabled: false dhcp: false ipv6: enabled: false dhcp: false bridge: port: - name: enp2s0 6 - name: br-ex - name: br-ex type: ovs-interface state: up copy-mac-from: enp2s0 ipv4: enabled: true dhcp: true address: - ip: "169.254.169.2" prefix-length: 29 ipv6: enabled: false dhcp: false address: - ip: "fd69::2" prefix-length: 125 1 Name of the policy. 2 Name of the interface. 3 The type of ethernet. 4 The requested state for the interface after creation. 5 Disables IPv4 and IPv6 in this example. 6 The node NIC to which the bridge is attached. 3.4. About the BareMetalHost resource Metal 3 introduces the concept of the BareMetalHost resource, which defines a physical host and its properties. The BareMetalHost resource contains two sections: The BareMetalHost spec The BareMetalHost status 3.4.1. The BareMetalHost spec The spec section of the BareMetalHost resource defines the desired state of the host. Table 3.1. BareMetalHost spec Parameters Description automatedCleaningMode An interface to enable or disable automated cleaning during provisioning and de-provisioning. When set to disabled , it skips automated cleaning. When set to metadata , automated cleaning is enabled. The default setting is metadata . The bmc configuration setting contains the connection information for the baseboard management controller (BMC) on the host. The fields are: address : The URL for communicating with the host's BMC controller. credentialsName : A reference to a secret containing the username and password for the BMC. disableCertificateVerification : A boolean to skip certificate validation when set to true . bootMACAddress The MAC address of the NIC used for provisioning the host. bootMode The boot mode of the host. It defaults to UEFI , but it can also be set to legacy for BIOS boot, or UEFISecureBoot . consumerRef A reference to another resource that is using the host. It could be empty if another resource is not currently using the host. For example, a Machine resource might use the host when the machine-api is using the host. description A human-provided string to help identify the host. externallyProvisioned A boolean indicating whether the host provisioning and deprovisioning are managed externally. When set: Power status can still be managed using the online field. Hardware inventory will be monitored, but no provisioning or deprovisioning operations are performed on the host. firmware Contains information about the BIOS configuration of bare metal hosts. Currently, firmware is only supported by iRMC, iDRAC, iLO4 and iLO5 BMCs. The sub fields are: simultaneousMultithreadingEnabled : Allows a single physical processor core to appear as several logical processors. Valid settings are true or false . sriovEnabled : SR-IOV support enables a hypervisor to create virtual instances of a PCI-express device, potentially increasing performance. Valid settings are true or false . virtualizationEnabled : Supports the virtualization of platform hardware. Valid settings are true or false . The image configuration setting holds the details for the image to be deployed on the host. Ironic requires the image fields. However, when the externallyProvisioned configuration setting is set to true and the external management does not require power control, the fields can be empty. The setting supports the following fields: url : The URL of an image to deploy to the host. checksum : The actual checksum or a URL to a file containing the checksum for the image at image.url . checksumType : You can specify checksum algorithms. Currently image.checksumType only supports md5 , sha256 , and sha512 . The default checksum type is md5 . format : This is the disk format of the image. It can be one of raw , qcow2 , vdi , vmdk , live-iso or be left unset. Setting it to raw enables raw image streaming in the Ironic agent for that image. Setting it to live-iso enables iso images to live boot without deploying to disk, and it ignores the checksum fields. networkData A reference to the secret containing the network configuration data and its namespace, so that it can be attached to the host before the host boots to set up the network. online A boolean indicating whether the host should be powered on ( true ) or off ( false ). Changing this value will trigger a change in the power state of the physical host. (Optional) Contains the information about the RAID configuration for bare metal hosts. If not specified, it retains the current configuration. Note OpenShift Container Platform 4.16 supports hardware RAID on the installation drive for BMCs, including: Fujitsu iRMC with support for RAID levels 0, 1, 5, 6, and 10 Dell iDRAC using the Redfish API with firmware version 6.10.30.20 or later and RAID levels 0, 1, and 5 OpenShift Container Platform 4.16 does not support software RAID on the installation drive. See the following configuration settings: hardwareRAIDVolumes : Contains the list of logical drives for hardware RAID, and defines the desired volume configuration in the hardware RAID. If you do not specify rootDeviceHints , the first volume is the root volume. The sub-fields are: level : The RAID level for the logical drive. The following levels are supported: 0 , 1 , 2 , 5 , 6 , 1+0 , 5+0 , 6+0 . name : The name of the volume as a string. It should be unique within the server. If not specified, the volume name will be auto-generated. numberOfPhysicalDisks : The number of physical drives as an integer to use for the logical drove. Defaults to the minimum number of disk drives required for the particular RAID level. physicalDisks : The list of names of physical disk drives as a string. This is an optional field. If specified, the controller field must be specified too. controller : (Optional) The name of the RAID controller as a string to use in the hardware RAID volume. rotational : If set to true , it will only select rotational disk drives. If set to false , it will only select solid-state and NVMe drives. If not set, it selects any drive types, which is the default behavior. sizeGibibytes : The size of the logical drive as an integer to create in GiB. If unspecified or set to 0 , it will use the maximum capacity of physical drive for the logical drive. softwareRAIDVolumes : OpenShift Container Platform 4.16 does not support software RAID on the installation drive. This configuration contains the list of logical disks for software RAID. If you do not specify rootDeviceHints , the first volume is the root volume. If you set HardwareRAIDVolumes , this item will be invalid. Software RAIDs will always be deleted. The number of created software RAID devices must be 1 or 2 . If there is only one software RAID device, it must be RAID-1 . If there are two RAID devices, the first device must be RAID-1 , while the RAID level for the second device can be 0 , 1 , or 1+0 . The first RAID device will be the deployment device, which cannot be a software RAID volume. Enforcing RAID-1 reduces the risk of a non-booting node in case of a device failure. The softwareRAIDVolume field defines the desired configuration of the volume in the software RAID. The sub-fields are: level : The RAID level for the logical drive.

The number of items should be greater than or equal to 2 . sizeGibibytes : The size of the logical disk drive as an integer to be created in GiB. If unspecified or set to 0 , it will use the maximum capacity of physical drive for logical drive. You can set the hardwareRAIDVolume as an empty slice to clear the hardware RAID configuration. For example: If you receive an error message indicating that the driver does not support RAID, set the raid , hardwareRAIDVolumes or softwareRAIDVolumes to nil. You might need to ensure the host has a RAID controller. The rootDeviceHints parameter enables provisioning of the RHCOS image to a particular device. It examines the devices in the order it discovers them, and compares the discovered values with the hint values. It uses the first discovered device that matches the hint value. The configuration can combine multiple hints, but a device must match all hints to get selected. The fields are: deviceName : A string containing a Linux device name like /dev/vda . The hint must match the actual value exactly. hctl : A string containing a SCSI bus address like 0:0:0:0 . The hint must match the actual value exactly. model : A string containing a vendor-specific device identifier. The hint can be a substring of the actual value. vendor : A string containing the name of the vendor or manufacturer of the device. The hint can be a sub-string of the actual value. serialNumber : A string containing the device serial number. The hint must match the actual value exactly. minSizeGigabytes : An integer representing the minimum size of the device in gigabytes. wwn : A string containing the unique storage identifier. The hint must match the actual value exactly. wwnWithExtension : A string containing the unique storage identifier with the vendor extension appended. The hint must match the actual value exactly. wwnVendorExtension : A string containing the unique vendor storage identifier.

Getting the BareMetalHost resource The BareMetalHost resource contains the properties of a physical host. You must get the BareMetalHost resource for a physical host to review its properties. Procedure Get the list of BareMetalHost resources: USD oc get bmh -n openshift-machine-api -o yaml Note You can use baremetalhost as the long form of bmh with oc get command. Get the list of hosts: USD oc get bmh -n openshift-machine-api Get the BareMetalHost resource for a specific host: USD oc get bmh <host_name> -n openshift-machine-api -o yaml Where <host_name> is the name of the host.

Editing a BareMetalHost resource After you deploy an OpenShift Container Platform cluster on bare metal, you might need to edit a node's BareMetalHost resource. Consider the following examples: You deploy a cluster with the Assisted Installer and need to add or edit the baseboard management controller (BMC) host name or IP address. You want to move a node from one cluster to another without deprovisioning it. Prerequisites Ensure the node is in the Provisioned , ExternallyProvisioned , or Available state. Procedure Get the list of nodes: USD oc get bmh -n openshift-machine-api Before editing the node's BareMetalHost resource, detach the node from Ironic by running the following command: USD oc annotate baremetalhost <node_name> -n openshift-machine-api 'baremetalhost.metal3.io/detached=true' 1 1 Replace <node_name> with the name of the node. Edit the BareMetalHost resource by running the following command: USD oc edit bmh <node_name> -n openshift-machine-api Reattach the node to Ironic by running the following command: USD oc annotate baremetalhost <node_name> -n openshift-machine-api 'baremetalhost.metal3.io/detached'- 3.7. Troubleshooting latency when deleting a BareMetalHost resource When the Bare Metal Operator (BMO) deletes a BareMetalHost resource, Ironic deprovisions the bare-metal host. For example, this might happen when scaling down a machine set. Deprovisioning involves a process known as "cleaning", which performs the following steps: Powering off the bare-metal host Booting a service RAM disk on the bare-metal host Removing partitioning metadata from all disks Powering off the bare-metal host again If cleaning does not succeed, the deletion of the BareMetalHost resource will take a long time and might not finish. Important Do not remove the finalizers to force deletion of a BareMetalHost resource. The provisioning back-end has its own database, which maintains a host record. Running actions will continue to run even if you try to force the deletion by removing the finalizers. You might face unexpected issues when attempting to add the bare-metal host later. Procedure If the cleaning process can recover, wait for it to finish. If cleaning cannot recover, disable the cleaning process by modifying the BareMetalHost resource and setting the automatedCleaningMode field to disabled . See "Editing a BareMetalHost resource" for additional details. 3.8. Attaching a non-bootable ISO to a bare-metal node You can attach a generic, non-bootable ISO virtual media image to a provisioned node by using the DataImage resource. After you apply the resource, the ISO image becomes accessible to the operating system after it has booted. This is useful for configuring a node after provisioning the operating system and before the node boots for the first time. Prerequisites The node must use Redfish or drivers derived from it to support this feature. The node must be in the Provisioned or ExternallyProvisioned state. The name must be the same as the name of the node defined in its BareMetalHost resource. You have a valid url to the ISO image. Procedure Create a DataImage resource: apiVersion: metal3.io/v1alpha1 kind: DataImage metadata: name: <node_name> 1 spec: url: "http://dataimage.example.com/non-bootable.iso" 2 1 Specify the name of the node as defined in its BareMetalHost resource. 2 Specify the URL and path to the ISO image. Save the DataImage resource to a file by running the following command: USD vim <node_name>-dataimage.yaml Apply the DataImage resource by running the following command: USD oc apply -f <node_name>-dataimage.yaml -n <node_namespace> 1 1 Replace <node_namespace> so that the namespace matches the namespace for the BareMetalHost resource. For example, openshift-machine-api . Reboot the node. Note To reboot the node, attach the reboot.metal3.io annotation, or reset set the online status in the BareMetalHost resource. A forced reboot of the bare-metal node will change the state of the node to NotReady for awhile. For example, 5 minutes or more. View the DataImage resource by running the following command: USD oc get dataimage <node_name> -n openshift-machine-api -o yaml Example output apiVersion: v1 items: - apiVersion: metal3.io/v1alpha1 kind: DataImage metadata: annotations: kubectl.kubernetes.io/last-applied-configuration: | {"apiVersion":"metal3.io/v1alpha1","kind":"DataImage","metadata":{"annotations":{},"name":"bmh-node-1","namespace":"openshift-machine-api"},"spec":{"url":"http://dataimage.example.com/non-bootable.iso"}} creationTimestamp: "2024-06-10T12:00:00Z" finalizers: - dataimage.metal3.io generation: 1 name: bmh-node-1 namespace: openshift-machine-api ownerReferences: - apiVersion: metal3.io/v1alpha1 blockOwnerDeletion: true controller: true kind: BareMetalHost name: bmh-node-1 uid: 046cdf8e-0e97-485a-8866-e62d20e0f0b3 resourceVersion: "21695581" uid: c5718f50-44b6-4a22-a6b7-71197e4b7b69 spec: url: http://dataimage.example.com/non-bootable.iso status: attachedImage: url: http://dataimage.example.com/non-bootable.iso error: count: 0 message: "" lastReconciled: "2024-06-10T12:05:00Z" 3.9. About the HostFirmwareSettings resource You can use the HostFirmwareSettings resource to retrieve and manage the BIOS settings for a host. When a host moves to the Available state, Ironic reads the host's BIOS settings and creates the HostFirmwareSettings resource. The resource contains the complete BIOS configuration returned from the baseboard management controller (BMC). Whereas, the firmware field in the BareMetalHost resource returns three vendor-independent fields, the HostFirmwareSettings resource typically comprises many BIOS settings of vendor-specific fields per host. The HostFirmwareSettings resource contains two sections: The HostFirmwareSettings spec. The HostFirmwareSettings status. 3.9.1. The HostFirmwareSettings spec The spec section of the HostFirmwareSettings resource defines the desired state of the host's BIOS, and it is empty by default. Ironic uses the settings in the spec.settings section to update the baseboard management controller (BMC) when the host is in the Preparing state. Use the FirmwareSchema resource to ensure that you do not send invalid name/value pairs to hosts. See "About the FirmwareSchema resource" for additional details. Example spec: settings: ProcTurboMode: Disabled 1 1 In the foregoing example, the spec.settings section contains a name/value pair that will set the ProcTurboMode BIOS setting to Disabled . Note Integer parameters listed in the status section appear as strings. For example, "1" . When setting integers in the spec.settings section, the values should be set as integers without quotes. For example, 1 . 3.9.2. The HostFirmwareSettings status The status represents the current state of the host's BIOS. Table 3.3. HostFirmwareSettings Parameters Description The conditions field contains a list of state changes. The sub-fields include: lastTransitionTime : The last time the state changed. message : A description of the state change. observedGeneration : The current generation of the status . If metadata.generation and this field are not the same, the status.conditions might be out of date. reason : The reason for the state change. status : The status of the state change. The status can be True , False or Unknown . type : The type of state change. The types are Valid and ChangeDetected . The FirmwareSchema for the firmware settings. The fields include: name : The name or unique identifier referencing the schema. namespace : The namespace where the schema is stored. lastUpdated : The last time the resource was updated. The settings field contains a list of name/value pairs of a host's current BIOS settings. 3.10. Getting the HostFirmwareSettings resource The HostFirmwareSettings resource contains the vendor-specific BIOS properties of a physical host. You must get the HostFirmwareSettings resource for a physical host to review its BIOS properties. Procedure Get the detailed list of HostFirmwareSettings resources: USD oc get hfs -n openshift-machine-api -o yaml Note You can use hostfirmwaresettings as the long form of hfs with the oc get command. Get the list of HostFirmwareSettings resources: USD oc get hfs -n openshift-machine-api Get the HostFirmwareSettings resource for a particular host USD oc get hfs <host_name> -n openshift-machine-api -o yaml Where <host_name> is the name of the host. 3.11. Editing the HostFirmwareSettings resource You can edit the HostFirmwareSettings of provisioned hosts. Important You can only edit hosts when they are in the provisioned state, excluding read-only values. You cannot edit hosts in the externally provisioned state. Procedure Get the list of HostFirmwareSettings resources: USD oc get hfs -n openshift-machine-api Edit a host's HostFirmwareSettings resource: USD oc edit hfs <host_name> -n openshift-machine-api Where <host_name> is the name of a provisioned host. The HostFirmwareSettings resource will open in the default editor for your terminal. Add name/value pairs to the spec.settings section: Example spec: settings: name: value 1 1 Use the FirmwareSchema resource to identify the available settings for the host. You cannot set values that are read-only. Save the changes and exit the editor. Get the host's machine name: USD oc get bmh <host_name> -n openshift-machine name Where <host_name> is the name of the host. The machine name appears under the CONSUMER field. Annotate the machine to delete it from the machineset: USD oc annotate machine <machine_name> machine.openshift.io/delete-machine=true -n openshift-machine-api Where <machine_name> is the name of the machine to delete. Get a list of nodes and count the number of worker nodes: USD oc get nodes Get the machineset: USD oc get machinesets -n openshift-machine-api Scale the machineset: USD oc scale machineset <machineset_name> -n openshift-machine-api --replicas=<n-1> Where <machineset_name> is the name of the machineset and <n-1> is the decremented number of worker nodes. When the host enters the Available state, scale up the machineset to make the HostFirmwareSettings resource changes take effect: USD oc scale machineset <machineset_name> -n openshift-machine-api --replicas=<n> Where <machineset_name> is the name of the machineset and <n> is the number of worker nodes. 3.12. Verifying the HostFirmware Settings resource is valid When the user edits the spec.settings section to make a change to the HostFirmwareSetting (HFS) resource, the Bare Metal Operator (BMO) validates the change against the FimwareSchema resource, which is a read-only resource. If the setting is invalid, the BMO will set the Type value of the status.Condition setting to False and also generate an event and store it in the HFS resource. Use the following procedure to verify that the resource is valid. Procedure Get a list of HostFirmwareSetting resources: USD oc get hfs -n openshift-machine-api Verify that the HostFirmwareSettings resource for a particular host is valid: USD oc describe hfs <host_name> -n openshift-machine-api Where <host_name> is the name of the host. Example output Events: Type Reason Age From Message ---- ------ ---- ---- ------- Normal ValidationFailed 2m49s metal3-hostfirmwaresettings-controller Invalid BIOS setting: Setting ProcTurboMode is invalid, unknown enumeration value - Foo Important If the response returns ValidationFailed , there is an error in the resource configuration and you must update the values to conform to the FirmwareSchema resource. 3.13. About the FirmwareSchema resource BIOS settings vary among hardware vendors and host models. A FirmwareSchema resource is a read-only resource that contains the types and limits for each BIOS setting on each host model. The data comes directly from the BMC through Ironic. The FirmwareSchema enables you to identify valid values you can specify in the spec field of the HostFirmwareSettings resource. The FirmwareSchema resource has a unique identifier derived from its settings and limits. Identical host models use the same FirmwareSchema identifier. It is likely that multiple instances of HostFirmwareSettings use the same FirmwareSchema . Table 3.4. FirmwareSchema specification Parameters Description The spec is a simple map consisting of the BIOS setting name and the limits of the setting. The fields include: attribute_type : The type of setting. The supported types are: Enumeration Integer String Boolean allowable_values : A list of allowable values when the attribute_type is Enumeration . lower_bound : The lowest allowed value when attribute_type is Integer . upper_bound : The highest allowed value when attribute_type is Integer . min_length : The shortest string length that the value can have when attribute_type is String . max_length : The longest string length that the value can have when attribute_type is String . read_only : The setting is read only and cannot be modified. unique : The setting is specific to this host. 3.14. Getting the FirmwareSchema resource Each host model from each vendor has different BIOS settings. When editing the HostFirmwareSettings resource's spec section, the name/value pairs you set must conform to that host's firmware schema. To ensure you are setting valid name/value pairs, get the FirmwareSchema for the host and review it. Procedure To get a list of FirmwareSchema resource instances, execute the following: USD oc get firmwareschema -n openshift-machine-api To get a particular FirmwareSchema instance, execute: USD oc get firmwareschema <instance_name> -n openshift-machine-api -o yaml Where <instance_name> is the name of the schema instance stated in the HostFirmwareSettings resource (see Table 3). 3.15. About the HostFirmwareComponents resource Metal 3 provides the HostFirmwareComponents resource, which describes BIOS and baseboard management controller (BMC) firmware versions. The HostFirmwareComponents resource contains two sections: The HostFirmwareComponents spec The HostFirmwareComponents status 3.15.1. HostFirmwareComponents spec The spec section of the HostFirmwareComponents resource defines the desired state of the host's BIOS and BMC versions. Table 3.5. HostFirmwareComponents spec Parameters Description The updates configuration setting contains the components to update. The fields are: component : The name of the component. The valid settings are bios or bmc . url : The URL to the component's firmware specification and version. 3.15.2. HostFirmwareComponents status The status section of the HostFirmwareComponents resource returns the current status of the host's BIOS and BMC versions. Table 3.6. HostFirmwareComponents status Parameters Description The components section contains the status of the components. The fields are: component : The name of the firmware component. It returns bios or bmc . initialVersion : The initial firmware version of the component. Ironic retrieves this information when creating the BareMetalHost resource. You cannot change it. currentVersion : The current firmware version of the component. Initially, the value matches the initialVersion value until Ironic updates the firmware on the bare-metal host. lastVersionFlashed : The last firmware version of the component flashed on the bare-metal host. This field returns null until Ironic updates the firmware. updatedAt : The timestamp when Ironic updated the bare-metal host's firmware. The updates configuration setting contains the updated components. The fields are: component : The name of the component. url : The URL to the component's firmware specification and version. 3.16. Getting the HostFirmwareComponents resource The HostFirmwareComponents resource contains the specific firmware version of the BIOS and baseboard management controller (BMC) of a physical host. You must get the HostFirmwareComponents resource for a physical host to review the firmware version and status. Procedure Get the detailed list of HostFirmwareComponents resources: USD oc get hostfirmwarecomponents -n openshift-machine-api -o yaml Get the list of HostFirmwareComponents resources: USD oc get hostfirmwarecomponents -n openshift-machine-api Get the HostFirmwareComponents resource for a particular host: USD oc get hostfirmwarecomponents <host_name> -n openshift-machine-api -o yaml Where <host_name> is the name of the host.
