Replacing the chassis

If your rack does not have additional space, you must uninstall the failed chassis and replace it with the new chassis.

Before you begin

  • You have an electrostatic discharge (ESD) wristband, or you have taken other antistatic protection.
  • You have the replacement chassis.
  • You have a lift or two or more persons to perform the steps.
  • You have a #1 Phillips screwdriver.
  • You have shut down the nodes correctly and physically removed them.

Steps

  1. Put on antistatic protection.
  2. Unpack the replacement chassis, and keep it on a level surface.
    Keep the packaging for when you return the failed unit to NetApp.
  3. Remove the failed chassis from the rack, and place it on a level surface.
    Note: Always use sufficient manpower or a lift while moving a chassis.
  4. Remove the rails.
  5. Install the new rails that were shipped to you with the replacement chassis.
  6. Slide the replacement chassis into the rack.
    Note: Always use sufficient manpower or a lift while moving a chassis.
  7. Secure the chassis to the rack with the front mounting thumb screws, and tighten the screws with the screwdriver.
  8. Install the nodes into the new chassis as follows:
    1. Reinstall the node into its original slot in the 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.
      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.
    2. For storage nodes, install the drives into their respective slots in the node by pressing down the cam handle on each drive until it clicks.
    3. 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.
  9. Verify that the nodes are online as follows:
    Option Steps
    If you reinstalled all the nodes (both storage and compute) in your NetApp HCI deployment
    1. In the VMware vSphere Web Client, confirm that the compute nodes (hosts) are listed in the ESXi cluster.
    2. In the Element plug-in for vCenter server, confirm that the storage nodes are listed under Active.
    If you reinstalled only the nodes in the failed chassis
    1. In the VMware vSphere Web Client, confirm that the compute nodes (hosts) are listed in the ESXi cluster.
    2. In the Element plug-in for vCenter server, click Cluster > Nodes > Pending.
    3. Select the node, and click Add.
      Note: It might take up to 15 minutes for the node to get added and be displayed under Nodes > Active.
    4. Click Drives.
    5. From the Available list, add the drives.
    6. Perform these steps for all the storage nodes you reinstalled.
  10. Verify that the volumes and datastores are up and accessible.
