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. 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 three resources to complete these tasks: BareMetalHost HostFirmwareSettings FirmwareSchema 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 and the FirmwareSchema resource to detail firmware specifications 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 3.1.1. Bare Metal Operator architecture The Bare Metal Operator (BMO) uses three 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. Additional resources Metal3 API service for provisioning bare-metal hosts Ironic API service for managing bare-metal infrastructure 3.2. 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 3.2.1. 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 doesn't require power control, the fields can be empty. The fields are: 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 4.11 supports hardware RAID for BMCs using the iRMC protocol only. OpenShift Container Platform 4.11 does not support software RAID. 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 don't 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 4.11 does not support software RAID. The following information is for reference only. This configuration contains the list of logical disks for software RAID. If you don't 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. Therefore, 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 following levels are supported: 0 , 1 , 1+0 . physicalDisks : A list of device hints. 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. The hint must match the actual value exactly. rotational : A boolean indicating whether the device should be a rotating disk (true) or not (false). 3.2.2. The BareMetalHost status The BareMetalHost status represents the host's current state, and includes tested credentials, current hardware details, and other information. Table 3.2. BareMetalHost status Parameters Description goodCredentials A reference to the secret and its namespace holding the last set of baseboard management controller (BMC) credentials the system was able to validate as working. errorMessage Details of the last error reported by the provisioning backend, if any. errorType Indicates the class of problem that has caused the host to enter an error state.

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.

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. 3.4.1. 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 . 3.4.2. 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. 3.5. 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. 3.6. 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/cluster-api-delete-machine=yes -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. 3.7. 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. 3.8. 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. 3.9. 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).
