Replace I/O module - AFX 1K

Contributors netapp-driley netapp-jsnyder

Replace an I/O module in your AFX 1K storage system when the module fails. The replacement process involves shutting down the controller, replacing the failed I/O module, rebooting the controller, and returning the failed part to NetApp.

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

Before you begin

  • You must have the replacement part available.

  • Make sure all other components in the storage system are functioning properly; if not, contact technical support.

Step 1: Shut down the impaired node

Shut down or take over the impaired controller.

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

About this task

  • If you have a cluster with more than four nodes, it must be in quorum. To view cluster information about your nodes, use the cluster show command. For more information about the cluster show command, see View node-level details in an ONTAP cluster.

  • If the cluster is not in quorum or if the health or eligibility of any controller (other than the impaired controller) shows as false, 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=<# of hours>h

    The following AutoSupport message suppresses automatic case creation for two hours:

    cluster1:> system node autosupport invoke -node * -type all -message MAINT=2h

  2. Disable automatic giveback from the console of the impaired controller:

    storage failover modify -node impaired-node -auto-giveback-of false

    Note When you see Do you want to disable auto-giveback?, enter y.

    1. If you are running ONTAP version 9.17.1 and the impaired controller cannot be brought up or is already taken over, you must take the HA interconnect link down from the healthy controller before booting up the impaired controller. This prevents the impaired controller from performing automatic giveback.

      system ha interconnect link off -node healthy-node -link 0

      system ha interconnect link off -node healthy-node -link 1

      Note If you are not running ONTAP version 9.17.1, skip the above step and go to step 3.

  3. Take the impaired controller to the LOADER prompt:

    If the impaired controller is displaying…​ Then…​

    The LOADER prompt

    Go to the next step.

    System prompt or password prompt

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

    The -halt true parameter brings the impaired node to the LOADER prompt.

Step 2: Replace a failed I/O module

To replace an I/O module, locate it within the enclosure and follow the specific sequence of steps.

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

  2. Unplug any cabling on the target I/O module.

    Note Make sure that you label where the cables were connected, so that you can connect them to the correct ports when you reinstall the module.

  3. Rotate the cable management tray down by pulling the buttons on both sides on the inside of the cable management tray and then rotate the tray down.

    Note This following illustration shows removing a horizontal and vertical I/O module. Typically, you will only remove one I/O module.

    Remove I/O module

    Callout number 1

    I/O cam latch

    Make sure that you label the cables so that you know where they came from.

  4. Remove the target I/O module from the enclosure:

    1. Depress the cam button on the target module.

    2. Rotate the cam latch away from the module as far as it will go.

    3. Remove the module from the enclosure by hooking your finger into the cam lever opening and pulling the module out of the enclosure.

      Make sure that you keep track of which slot the I/O module was in.

  5. Set the I/O module aside.

  6. Install the replacement I/O module into the enclosure:

    1. Align the module with the edges of the enclosure slot opening.

    2. Gently slide the module into the slot all the way into the enclosure, and then rotate the cam latch all the way up to lock the module in place.

  7. Re-cable the I/O module.

  8. Rotate the cable management tray up to the closed position.

Step 3: Reboot the controller

After you replace an I/O module, you must reboot the controller.

  1. Reboot the controller from the LOADER prompt:

    bye

    Note Rebooting the impaired controller also reinitializes the I/O modules and other components.

  2. Press <enter> when console messages stop.

    • If you see the login prompt, go to the next step.

    • If you do not see login prompt, log into the partner node.

  3. Give back only the root with override-destination-checks option:

    storage failover giveback -ofnode impaired-node -only-root true -override -destination-checks true

    Note The following command is only available in the Diagnostic mode privilege level. For more information on privilege levels, see Understand the privilege levels for ONTAP CLI commands.

    If you encounter errors, contact NetApp Support.

  4. Wait 5 minutes after the giveback report completes, and check failover status and giveback status:

    storage failover show and storage failover show-giveback

    Note The following command is only available in the Diagnostic mode privilege level.

  5. If the HA internconnect links were taken down, bring them back up:

    system ha interconnect link on -node healthy-node -link 0

    system ha interconnect link on -node healthy-node -link 1

  6. If automatic giveback was disabled, reenable it:

    storage failover modify -ofnode impaired-node -automatic-giveback true

  7. Return the impaired controller to normal operation by giving back its storage:

    storage failover giveback -ofnode impaired_node_name

  8. Restore automatic giveback from the console of the healthy controller:

    storage failover modify -node local -auto-giveback-of true

  9. If AutoSupport is enabled, restore/unsuppress automatic case creation:

    system node autosupport invoke -node * -type all -message MAINT=END

Step 4: 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.
