Hot-swap a drive - NX224 shelves

You can replace a failed drive nondisruptively in an NX224 shelf that is powered on, and while I/O is in progress.

Before you begin

  • The drive that you are installing must be supported by the NX224 shelf. You can verify your shelf's compatible drives in the NetApp Hardware Universe.

  • If SED authentication is enabled, you must use the SED replacement instructions in the ONTAP documentation.

    You can view the additional steps that must be completed before and after replacing an SED in the NetApp encryption overview with the CLI documentation.

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

  • Verify that the drive you are removing is failed.

    You can verify that the drive is failed by running the storage disk show -broken command. The failed drive appears in the list of failed drives. If it does not, you should wait, and then run the command again.

    Note Depending on the drive type and capacity, it can take up to several hours for the drive to appear in the list of failed drives.
About this task

  • Best practice: Ensure your system can recognize and use newly qualified drives by downloading the current version of the Disk Qualification Package.

    This avoids system event messages about having noncurrent drive information and prevention of drive partitioning because drives are not recognized. The DQP also notifies you of noncurrent drive firmware.

  • Best practice: The best practice is to have current versions of NVMe shelf module (NSM) firmware and drive firmware on your system before replacing FRU components. You can visit the NetApp Support Site to download disk shelf firmware and download disk drive firmware.

    Note

    Do not revert firmware to a version that does not support your shelf and its components.

  • Drive firmware is automatically updated (nondisruptively) on new drives that have non-current firmware versions.

    Note Drive firmware checks occur every two minutes.

  • If needed, you can turn on the shelf's location (blue) LEDs to aid in physically locating the affected shelf: storage shelf location-led modify -shelf-name shelf_name -led-status on

    If you do not know the shelf_name of the affected shelf, run the storage shelf show command.

    A shelf has three location LEDs: one on the operator display panel and one on each NSM. Location LEDs remain illuminated for 30 minutes. You can turn them off by entering the same command, but using the off option.

  • When you unpack the replacement drive, save all packing materials for use when you return the failed drive.

    If you need the RMA number or additional help with the replacement procedure, contact technical support at NetApp Support, 888-463-8277 (North America), 00-800-44-638277 (Europe), or +800-800-80-800 (Asia/Pacific).

Steps

  1. Properly ground yourself.

  2. Physically identify the failed drive.

    When a drive fails, the system logs a warning message to the system console indicating which drive failed. Additionally, the attention (amber) LED on the shelf operator display panel and the failed drive illuminate.

    Note The activity (green) LED on a failed drive can be illuminated (solid), which indicates that the drive has power, but should not be blinking, which indicates I/O activity. A failed drive has no I/O activity.

  3. Remove the failed drive:

    Remove drive.
    Callout number 1

    Press the release button on the drive face to open the cam handle.
    Callout number 2

    Rotate the cam handle downward to disengage the drive from the midplane.
    Callout number 3

    Slide the drive out of the shelf using the cam handle and supporting the drive with your other hand.

  4. Wait a minimum of 70 seconds before inserting the replacement drive.

    This allows the system to recognize that a drive was removed.

  5. Insert the replacement drive:

    1. With the cam handle in the open position, use both hands to insert the drive.

    2. Gently push until the drive stops.

    3. Close the cam handle so that the drive is fully seated into the mid plane and the handle clicks into place.

      Be sure to close the cam handle slowly so that it aligns correctly with the face of the drive.

  6. Verify that the drive's activity (green) LED is illuminated.

    When the drive's activity LED is solid, it means that the drive has power. When the drive's activity LED is blinking, it means that the drive has power and I/O is in progress. If the drive firmware is automatically updating, the LED blinks.

  7. If you are replacing another drive, repeat steps 3 through step 7.
