Hot-swapping a disk drive in a DS460C disk shelf

You can hot-swap a failed disk drive in a DS460C 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. Identify the failed disk drive from the system console warning message and the illuminated amber attention LED on the drive drawer.

    The 2.5-inch and 3.5-inch SAS drive carriers do not contain LEDs. Instead, you must look at the Attention LEDs on the drive drawers to determine which drive has failed.

    The drive drawer's Attention LED (amber) blinks so you can open the correct drive drawer to identify which drive to replace.

    The drive drawer's Attention LED is on the front-left side in front of each drive, with a warning symbol on the drive handle just behind the LED.

  5. Open the drawer containing the failed drive:
    1. Unlatch the drive drawer by pulling on both levers.
    2. Using the extended levers, carefully pull the drive drawer out until it stops.
    3. Look at the top of the drive drawer to find the Attention LED that resides on the drawer in front of each drive.
  6. Remove the failed drive from the open drawer:
    1. Gently pull back the orange release latch that is in front of the drive you want to remove.

      1 Orange release latch
    2. Open the cam handle, and lift out the drive slightly.
    3. Wait 30 seconds.
    4. Use the cam handle to lift the drive from the shelf.
    5. Place the drive on an antistatic, cushioned surface away from magnetic fields.
  7. Insert the replacement drive in the drawer:
    1. Raise the cam handle on the new drive to vertical.
    2. Align the two raised buttons on each side of the drive carrier with the matching gap in the drive channel on the drive drawer.
      1 Raised button on the right side of the drive carrier
    3. Lower the drive straight down, and then rotate the cam handle down until the drive snaps into place under the orange release latch.
    4. Carefully push the drive drawer back into the enclosure.


      Attention: Possible loss of data access – Never slam the drawer shut. Push the drawer in slowly to avoid jarring the drawer and causing damage to the storage array.
    5. Close the drive drawer by pushing both levers towards the center.
      The green Activity LED for the replaced drive on the front of the drive drawer comes on when the drive is inserted correctly.
  8. If you are replacing another disk drive, repeat Steps 4 through 7.
  9. Check the Activity LED and the Attention LED on the drive you replaced.
    LED status Description
    The Activity LED is on or blinking, and the Attention LED is off The new drive is working correctly.
    The Activity LED is off The drive might not be installed correctly. Remove the drive, wait 30 seconds, and then reinstall it.
    The Attention LED is on The new drive might be defective. Replace it with another new drive.
    Note: When you first insert a drive, its Attention LED might be on. However, the LED should go off within a minute.
  10. 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.
  11. Return the failed part to NetApp, as described in the RMA instructions shipped with the kit.
    Contact technical support at NetApp Support, 888-463-8277 (North America), 00-800-44-638277 (Europe), or +800-800-80-800 (Asia/Pacific) if you need the RMA number or additional help with the replacement procedure.
