About this task

  • 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.
  1. Shutting down the impaired controller
    You can shut down or take over the impaired controller using different procedures, depending on the storage system hardware configuration.
  2. Removing the controller module
    To access components inside the controller module, you must remove the controller module from the chassis.
  3. Replacing a PCIe card
    To replace a PCIe card, you must locate the failed PCIe card, remove the riser that contains the card from the controller module, replace the card, and then reinstall the PCIe riser in the controller module.
  4. Replacing the mezzanine card
    The mezzanine card is located under riser number 3 (slots 4 and 5). You must remove that riser to access the mezzanine card, replace the mezzanine card, and then reinstall riser number 3. See the FRU map on the controller module for more information.
  5. Installing the controller module
    After you have replaced the component in the controller module, you must re-install the controller module into the chassis, and then boot it to Diagnostics menu.
  6. Restoring the controller module to operation after running diagnostics
    After completing diagnostics, you must recable the system, give back storage owned by the controller module, and then reenable automatic giveback.
  7. Completing the replacement process
    After you replace the part, you can return the failed part to Lenovo, as described in the RMA instructions shipped with the kit. Contact technical support at Lenovo Data Center Support if you need the RMA number or additional help with the replacement procedure.
