Hot-swapping a disk drive in a DS224C or DS212C disk shelf

You can hot-swap a failed disk drive in a DS224C or DS212C disk shelf—nondisruptively replace a disk drive in a system that is powered on and serving data (I/O is in progress).

Before you begin

About this task

Steps

  1. If you want to manually assign disk ownership for the replacement disk drive, you need to disable disk ownership automatic assignment if it is enabled; otherwise, go to the next step.
    Note: You need to manually assign disk ownership if disk drives in the stack are owned by both controllers in an HA pair.
    Note: You manually assign disk ownership and then reenable disk ownership automatic assignment later in this procedure.
    1. Verify if disk ownership automatic assignment is enabled:storage disk option show
      If you have an HA pair, you can enter the command at the console of either controller.
      If disk ownership automatic assignment is enabled, the output shows "on" (for each controller) in the "Auto Assign" column.
    2. If disk ownership automatic assignment is enabled, you need to disable it:storage disk option modify -node node_name -autoassign off
      You need to disable disk ownership automatic assignment on both controllers in an HA pair.
  2. Properly ground yourself.
  3. Unpack the new disk drive, and set it on a level surface near the disk shelf.
    Save all packaging materials for use when returning the failed disk drive.
    Note: NetApp requires that all returned disk drives be in a ESD-rated bag.
  4. Physically identify the failed disk drive from the system console warning message and the illuminated attention (amber) LED on the disk drive.
    Note: The activity (green) LED on a failed disk drive can be illuminated (solid), which indicates the disk drive has power, but should not be blinking, which indicates I/O activity. A failed disk drive has no I/O activity.
  5. Press the release button on the disk drive face, and then pull the cam handle to its fully open position to release the disk drive from the mid plane.
    When you press the release button, the cam handle on the disk drive springs open partially.
    Note: Disk drives in a DS212C disk shelf are arranged horizontally with the release button located on the left of the disk drive face. Disk drives in a DS224C disk shelf are arranged vertically with the release button located at the top of the disk drive face.

  6. Slide out the disk drive slightly to allow the disk to safely spin down, and then remove the disk drive from the disk shelf.
    An HDD can take up to one minute to safely spin down.
    Note: When handling a disk drive, always use two hands to support its weight.
  7. Using two hands, with the cam handle in the open position, insert the replacement disk drive into the disk shelf, firmly pushing until the disk drive stops.
    Note: Wait a minimum of 10 seconds before inserting a new disk drive. This allows the system to recognize that a disk drive was removed.
    Note: Do not place hands on the disk drive boards that are exposed on the underside of the disk carrier.
  8. Close the cam handle so that the disk 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 disk drive.
  9. If you are replacing another disk drive, repeat Steps 3 through 8.
  10. Verify the disk drive's activity (green) LED is illuminated.
    When the disk drive's activity LED is solid green, it means the disk drive has power. When the disk drive's activity LED is blinking, it means the disk drive has power and I/O is in progress. If the disk drive firmware is automatically updating, the LED will be blinking.
  11. If you disabled disk ownership automatic assignment in Step 1, manually assign disk ownership, and then reenable disk ownership automatic assignment if needed:
    1. Display all unowned disks:storage disk show -container-type unassigned
    2. Assign each disk:storage disk assign -disk disk_name -owner owner_name
      You can use the wildcard character to assign more than one disk at once.
    3. Reenable disk ownership automatic assignment if needed:storage disk option modify -node node_name -autoassign on
      You need to reenable disk ownership automatic assignment on both controllers in an HA pair.
  12. Return the failed part to NetApp, as described in the RMA instructions shipped with the kit.
