Replace the boot media for automated boot recovery - AFF A70 and AFF A90

The boot media in your AFF A70 or AFF A90 storage system stores essential firmware and configuration data. The replacement process involves removing the System Management module, removing the impaired boot media, installing the replacement boot media in the System Management module, and then reinstalling the System Management module.

The automated boot media recovery process is supported only in ONTAP 9.17.1 and later. If your storage system is running an earlier version of ONTAP, use the manual boot recovery procedure.

Replace the boot media, which is located inside the System Management module at the rear of the controller.

Before you begin

  • You must have a replacement boot media.

  • Have an anti-static mat available for the System Management module.

Steps

  1. Verify that NVRAM destage has completed before proceeding. When the LED on the NV module is off, NVRAM is destaged.

    If the LED is flashing, wait for the flashing to stop. If flashing continues for longer than 5 minutes, contact NetApp Support for assistance.

  2. Go to the rear of the chassis and properly ground yourself if you are not already grounded.

  3. Disconnect power from the controller:

    • For AC power supplies, disconnect the power cords from the power supplies.

    • For DC power supplies, disconnect the power block from the power supplies.

  4. Remove the System Management module:

    1. Remove any cables connected to the System Management module. Label the cables to identify their correct ports for reinstallation.

    2. Rotate the cable management arm down by pulling the buttons on both sides of the cable management arm.

    3. Depress the system management cam button.

      The cam lever moves away from the chassis.

    4. Rotate the cam lever all the way down and remove the System Management module from the controller.

    5. Place the System Management module on an anti-static mat with the boot media accessible.

  5. Remove the boot media from the System Management module:

    1. Press the blue locking button.

    2. Rotate the boot media up, slide it out of the socket, and set it aside.

  6. Install the replacement boot media into the System Management module:

    1. Align the edges of the boot media with the socket housing, and then gently push it squarely into the socket.

    2. Rotate the boot media down toward the locking button.

    3. Push the locking button, rotate the boot media all the way down, and then release the locking button.

  7. Reinstall the System Management module:

    1. Align the edges of the System Management module with the chassis opening.

    2. Gently slide the module into the chassis until the cam latch begins to engage.

    3. Rotate the cam latch all the way up to lock the module in place.

    4. Reconnect the cables to the System Management module using the labels you created during removal.

    5. Rotate the cable management arm up to the closed position.

  8. Reconnect power to the controller:

    • For AC power supplies, plug the power cords into the power supplies.

    • For DC power supplies, reconnect the power block to the power supplies.

      The controller automatically reboots when power is restored.

  9. Interrupt the boot process by pressing Ctrl-C to stop at the LOADER prompt.
