Moving the compute node

Before you move the compute node to the new chassis, you must migrate the virtual machines (VMs), shut it down correctly, and label the cables inserted into the node.

Before you begin

  • If your rack has additional space for a new chassis, you have installed the new chassis in the available space.
  • If your rack does not have additional space for a new chassis, you have verified that other chassis in your deployment have unused node slots available.
  • You have an electrostatic discharge (ESD) wristband, or you have taken other antistatic protection.


  1. Note down the serial number of the node from the sticker at the back of the node.
  2. In the VMware vSphere Web Client, click Hosts and Clusters, and select a node (host), and click Monitor > Hardware Status > Sensors.
  3. Check if the Node 0 serial number displayed matches the serial number you noted down from the sticker at the back of the node.

    In this figure, the serial number of the compute node is highlighted.
    • If the serial numbers match, proceed to Step 4.
    • If the serial numbers do not match, go to the next node listed under Hosts and Clusters, and look for the serial number. Do this until you find the matching serial number.
  4. Migrate the virtual machines (VMs) to another available host.
    See the VMware documentation for the migration steps.
  5. Right-click the node, and click Power > Shut Down.
    You are now ready to perform the steps for physically removing the node from the chassis.
  6. Label the node and all the cables at the back of the node.
  7. Remove the node from the chassis by pulling down the cam handle on the right side of each node, and pulling the node out using both the cam handles.
  8. Reinstall the node into the new chassis by pushing the node in until you hear a click.
    The labels you had on the node before you removed it will help guide you. The node powers on automatically when you install it correctly.
    Attention: Ensure that you support the node from under when you install it. Do not use excessive force while pushing the node into the chassis.
    Note: If installing into the new chassis, ensure that you install the node into its original slot in the chassis.
  9. Reconnect the cables to the same ports at the back of the node.
    The labels you had on the cables when you disconnected them will help guide you.
    Attention: Ensure that you do not force the cables into the ports; you might damage the cables, ports, or both.
  10. Confirm that the compute node (host) is listed in the ESXi cluster in the VMware vSphere Web Client.
  11. Perform these steps for all the compute nodes in the failed chassis.
