Replace the mezzanine card by disconnecting the cables and any SFP and QSFP modules from the card, replace the failed mezzanine card, and then recable the cards.

  • You can use this procedure with all versions of ONTAP supported by your system

  • All other components in the system must be functioning properly; if not, you must contact technical support.

Animation - Replace the mezzanine card

Step 1: Shut down the impaired controller

To shut down the impaired controller, you must determine the status of the controller and, if necessary, take over the controller so that the healthy controller continues to serve data from the impaired controller storage.

If you have a cluster with more than two nodes, it must be in quorum. If the cluster is not in quorum or a healthy controller shows false for eligibility and health, you must correct the issue before shutting down the impaired controller; see Synchronize a node with the cluster.

Steps

  1. If AutoSupport is enabled, suppress automatic case creation by invoking an AutoSupport message: system node autosupport invoke -node * -type all -message MAINT=_number_of_hours_down_h

    The following AutoSupport message suppresses automatic case creation for two hours: cluster1:*> system node autosupport invoke -node * -type all -message MAINT=2h

  2. If the impaired controller is part of an HA pair, disable automatic giveback from the console of the healthy controller: storage failover modify -node local -auto-giveback false

  3. Take the impaired controller to the LOADER prompt:

    If the impaired controller is displaying…​ Then…​

    The LOADER prompt

    Go to Remove controller module.

    Waiting for giveback…​

    Press Ctrl-C, and then respond y.

    System prompt or password prompt (enter system password)

    Take over or halt the impaired controller from the healthy controller: storage failover takeover -ofnode impaired_node_name

    When the impaired controller shows Waiting for giveback…​, press Ctrl-C, and then respond y.

Step 2: Remove the controller module

Remove the controller module from the system and then remove the cover on the controller module.

Steps

  1. If you are not already grounded, properly ground yourself.

  2. Loosen the hook and loop strap binding the cables to the cable management device, and then unplug the system cables and SFPs (if needed) from the controller module, keeping track of where the cables were connected.

    Leave the cables in the cable management device so that when you reinstall the cable management device, the cables are organized.

  3. Remove and set aside the cable management devices from the left and right sides of the controller module.

  4. Squeeze the latch on the cam handle until it releases, open the cam handle fully to release the controller module from the midplane, and then, using two hands, pull the controller module out of the chassis.

  5. Turn the controller module over and place it on a flat, stable surface.

  6. Open the cover by pressing the blue buttons on the sides of the controller module to release the cover, and then rotate the cover up and off of the controller module.

Step 3: Replace the mezzanine card

Replace the mezzanine card.

  1. If you are not already grounded, properly ground yourself.

  2. Remove the mezzanine card using the following illustration or the FRU map on the controller module:

    drw 2850 replace HIC IEOPS 700
    Callout number 1

    IO Plate
    icon round 2

    PCIe mezzanine card

    1. Remove the IO Plate by sliding it straight out from thr controller module.

    2. Loosen the thumbscrews on the mezzanine card and lift the mezzanine card straight up.

      Note You can loosen the thumbscrews with your fingers or a screwdriver. If you use your fingers, you might need to rotate the NV battery up for better finger purchase on the thumbscrew next to it.

  3. Reinstall the mezzanine card:

    1. Align the socket on the replacement mezzanine card plug with the socket on the motherboard, and then gently seat the card squarely into the socket.

    2. Tighten the three thumbscrews on the mezzanine card.

    3. Reinstall the IO Plate.

  4. Reinstall the controller module cover and lock it into place.

Step 4: Install the controller module

Reinstall the controller module.

Steps

  1. If you are not already grounded, properly ground yourself.

  2. If you have not already done so, replace the cover on the controller module.

  3. Turn the controller module over and align the end with the opening in the chassis.

  4. Gently push the controller module halfway into the system.Align the end of the controller module with the opening in the chassis, and then gently push the controller module halfway into the system.

    Note Do not completely insert the controller module in the chassis until instructed to do so.

  5. Recable the system, as needed.

    If you removed the media converters (QSFPs or SFPs), remember to reinstall them if you are using fiber optic cables.

  6. Complete the reinstallation of the controller module:

    1. With the cam handle in the open position, firmly push the controller module in until it meets the midplane and is fully seated, and then close the cam handle to the locked position.

      Note Do not use excessive force when sliding the controller module into the chassis to avoid damaging the connectors.

      The controller begins to boot as soon as it is seated in the chassis.

    2. If you have not already done so, reinstall the cable management device.

    3. Bind the cables to the cable management device with the hook and loop strap.

  7. Return the controller to normal operation by giving back its storage: storage failover giveback -ofnode impaired_node_name

  8. Restore automatic giveback by using the storage failover modify -node local -auto-giveback true command.

  9. If an AutoSupport maintenance window was triggered, end it by using the system node autosupport invoke -node * -type all -message MAINT=END command.

Step 5: Return the failed part to NetApp

Return the failed part to NetApp, as described in the RMA instructions shipped with the kit. See the Part Return and Replacements page for further information.
