Replace the mezzanine card in your FAS2820 system if the card fails or upgrade it to a different protocol by installing a new card.

  • Use this procedure with any ONTAP version supported by your system.

  • Replace the mezzanine card with the same type or a different type.

  • Write down the ifgrp and VLAN information before shutting down the controller.

  • If changing mezzanine card types, change LIF and port settings after the controller restarts.

  • Verify that all other system components are working. If the issue persists, call technical support.

Animation - Replace the mezzanine card

Step 1: Shut down the impaired controller

Before you begin

  • If you are changing mezzanine card types, capture the impaired node’s ifgrp and VLAN information.

    network port vlan show -node _impaired_node_name_
network port ifgrp show -node _impaired_node_name_

Take over and halt the impaired controller so that the healthy controller continues to serve data from the impaired controller's storage. To do this, you suppress automatic case creation in AutoSupport, disable automatic giveback, and bring the impaired controller to the LOADER prompt. The LOADER prompt is the safe halted state from which you can replace the FRU.

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 and its cover.

Steps

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

  2. Loosen the hook and loop strap, note where the cables are connected, and then unplug the system cables and SFPs (if needed).

    Leave the cables in the cable management device to keep them organized.

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

  4. Release the cam handle latch, open it fully, and pull the controller module out of the chassis.

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

  6. Press the blue buttons on the sides of the controller module to release the cover. Rotate the cover up and off 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:

    Callout number 1

    IO Plate
    Callout number 2

    PCIe mezzanine card

    1. Remove the IO Plate by sliding it straight out from the 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 connector on the replacement mezzanine card with the socket on the motherboard, and then gently seat the card squarely in the socket.

    2. Tighten the three thumbscrews on the mezzanine card.

    3. Reinstall the IO Plate.

  4. Put the controller module cover back on and lock it.

Step 4: Install and reboot the controller module

Reinstall and reboot the controller module.

Steps

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

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

  3. Gently push the controller module halfway into the chassis.

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

  4. Reconnect the system cables as needed.

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

  5. Complete the reinstallation of the controller module:

    1. With the cam handle open, firmly push the controller module in until fully seated. Close the cam handle to lock.

      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. == Step 5: Reconfigure the mezzanine card (if type changed)

After the controller restarts, change the mezzanine card settings to match the new card if you replaced it with a different type.

Option 1: Fibre Channel to Ethernet mezzanine card

Configure the Ethernet replacement mezzanine card by updating LIFs and port settings as needed.

Steps

  1. Use the network port show command to confirm new port names and link states.

  2. Rebuild any ifgrps and VLANs on the new Ethernet mezzanine ports.

  3. Put the new ports, or ifgrp/VLAN ports, in the correct broadcast domains and IPspaces, and set MTU values.

  4. Update affected LIF home port and failover settings.

  5. Delete LIFs that are no longer needed.

See Learn about ONTAP network port configuration for more detailed information about configuring Ethernet in ONTAP.

Option 2: Ethernet to Fibre Channel mezzanine card

Configure the replacement FC mezzanine card by updating LIFs and port settings as needed.

Steps

  1. Enable FCP on relevant SVMs. Create new data LIFs.

  2. Update fabric zoning and host paths. Update portset, igroup, and LUN mappings as needed.

  3. Verify host multipath. Confirm there are no stale paths and that paths are balanced between optimized and non-optimized paths.

  4. Verify no LIFs are homed on removed Ethernet ports, all FC LIFs are up and serving I/O, and AutoSupport monitoring reflects the new configuration.

See SAN management overview for more detailed information about configuring Fibre Channel in ONTAP.

Step 6: Return the controller to normal operation

Give back storage to the impaired controller, restore automatic giveback, and end the AutoSupport maintenance window.

  1. From the healthy controller or a cluster admin prompt, bring the controller back to normal operation by restoring its storage: storage failover giveback -ofnode impaired_node_name

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

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

Step 7: 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.
