OpenShift Container Platform

Retrieving the host firmware schema for a managed cluster

You can discover the host firmware schema for managed clusters. The host firmware schema for bare-metal hosts is populated with information that the Ironic API returns. The API returns information about host firmware interfaces, including firmware setting types, allowable values, ranges, and flags.

Prerequisites

You have installed the OpenShift CLI (oc).
You have installed Red Hat Advanced Cluster Management (RHACM) and logged in to the hub cluster as a user with cluster-admin privileges.
You have provisioned a cluster that is managed by RHACM.

Procedure

Discover the host firmware schema for the managed cluster. Run the following command:

$ oc get firmwareschema -n <managed_cluster_namespace> -o yaml

The following example output shows the host firmware schema:
