Replace SSD Drive - AFF A70 and AFF A90

You can replace a failed SSD drive nondisruptively while I/O is in progress.

When a drive fails, the platform logs a warning message to the system console indicating which drive has failed. In addition, both the fault LED on the operator display panel and the fault LED on the failed drive are illuminated.

Before you begin

  • Follow best practice and install the current version of the Disk Qualification Package (DQP) before replacing a drive.

  • Identify the failed disk drive by running the storage disk show -broken command from the system console.

    The failed drive appears in the list of failed drives. If it does not, you should wait, and then run the command again.

    Note It can take up to several hours for the drive to appear in the list of failed drives.

  • Determine whether SED authentication is enabled.

    How you replace the disk depends on how the disk drive is being used. If SED authentication is enabled, you must use the SED replacement instructions in the ONTAP 9 NetApp Encryption Power Guide. These Instructions describe additional steps you must perform before and after replacing an SED.

  • Make sure the replacement drive is supported by your platform. See the NetApp Hardware Universe.

  • Make sure all other components in the system are functioning properly; if not, you must contact technical support.

About this task

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

When replacing several disk drives, you must wait 70 seconds between the removal of each failed disk drive and the insertion of the replacement disk drive to allow the storage system to recognize the existence of each new disk.

Steps

  1. If you want to manually assign drive ownership for the replacement drive, you need to disable automatic drive assignment replacement drive, if it is enabled

    Note You manually assign drive ownership and then reenable automatic drive assignment later in this procedure.

    1. Verify whether automatic drive assignment is enabled: storage disk option show

      You can enter the command on either controller module.

      If automatic drive assignment is enabled, the output shows on in the “Auto Assign” column (for each controller module).

    2. If automatic drive assignment is enabled, disable it: storage disk option modify -node node_name -autoassign off

      You must disable automatic drive assignment on both controller modules.

  2. Properly ground yourself.

  3. 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 drive 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.

  4. Remove the failed drive:

    1. Press the release button on the drive face to open the cam handle.

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

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

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

  6. Insert the replacement drive:

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

    2. Push until the drive stops.

    3. Close the cam handle so that the drive is fully seated into the midplane 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.

  7. 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.

  8. If you are replacing another drive, repeat Steps 3 through 7.

  9. If you disabled automatice drive assignment in Step 1, then, manually assign drive ownership and then reenable automatic drive assignment if needed.

    1. Display all unowned drives: storage disk show -container-type unassigned

      You can enter the command on either controller module.

    2. Assign each drive: storage disk assign -disk disk_name -owner node_name

      You can enter the command on either controller module.

      You can use the wildcard character to assign more than one drive at once.

    3. Reenable automatic drive assignment if needed: storage disk option modify -node node_name -autoassign on

      You must reenable automatic drive assignment on both controller modules.

  10. Return the failed part to NetApp, as described in the RMA instructions shipped with the kit.
