Verifying AMD GPU availability on your cluster

Before you proceed with the AMD GPU Operator installation process, you can verify the presence of an AMD GPU device on a node within your {openshift-platform} cluster. You can use commands such as lspci or oc to confirm hardware and resource availability.

Prerequisites

  • You have administrative access to the {openshift-platform} cluster.

  • You have a running {openshift-platform} cluster with a node equipped with an AMD GPU.

  • You have access to the OpenShift CLI (oc) and terminal access to the node.

Procedure

  1. Use the OpenShift CLI to verify if GPU resources are allocatable:

    1. List all nodes in the cluster to identify the node with an AMD GPU:

      oc get nodes

    2. Note the name of the node where you expect the AMD GPU to be present.

    3. Describe the node to check its resource allocation:

      oc describe node <node_name>

    4. In the output, locate the Capacity and Allocatable sections and confirm that amd.com/gpu is listed. For example:

      Capacity:
  amd.com/gpu:  1
Allocatable:
  amd.com/gpu:  1

  2. Check for the AMD GPU device using the lspci command:

    1. Log in to the node:

      oc debug node/<node_name>
chroot /host

    2. Run the lspci command and search for the supported AMD device in your deployment. For example:

      lspci | grep -E "MI210|MI250|MI300"

    3. Verify that the output includes one of the AMD GPU models. For example:

      03:00.0 Display controller: Advanced Micro Devices, Inc. [AMD] Instinct MI210

  3. Optional: Use the rocminfo command if the ROCm stack is installed on the node:

    rocminfo

    1. Confirm that the ROCm tool outputs details about the AMD GPU, such as compute units, memory, and driver status.

Verification

  • The oc describe node <node_name> command lists amd.com/gpu under Capacity and Allocatable.

  • The lspci command output identifies an AMD GPU as a PCI device matching one of the specified models (for example, MI210, MI250, MI300).

  • Optional: The rocminfo tool provides detailed GPU information, confirming driver and hardware configuration.
