Prerequisites

 

  • Wear a wrist strap connected to the storage system to prevent part failures caused by static electricity. Do not remove the wrist strap until you finish the procedure.
  • Confirm that the storage system power is turned on.

 

Confirm the blocked drive

 

  1. Start the maintenance utility.
  2. In the Maintenance Utility window, click Hardware > Controller Chassis or Hardware > Drive Box.
  3. Click the Drives tab.

  4. In the Status column, confirm that Warning, Failed, Blocked, Copy incomplete, or Reserved appears for the drive you want to replace.
  5. Remove the front bezel and check whether the red ALM LED on the failed drive is on or off:
    · If the LED is on, replace the drive.
    · If the LED is off:

- In the Drives tab of the maintenance utility, check the blocked drive, and then click Block.

- Confirm that the drive shown in the Block Drives window (for example, HDD00-03 in the following figure) matches the number of the slot containing the failed drive, and then click Block.

- If prompted about whether you want to perform sparing, click Yes.

- Click Close and replace the drive.

 

Replace the drive

 

Facing the front of the chassis, drive numbering in a chassis is #0 to #23, from left to right.

  1. Remove the front bezel.
  2. Pull up the stopper of the drive handle toward you, to release the lock.
  3. Open the handle toward you, and then gently remove the drive to be replaced. Handle the drive with care.
  4. Place the drive into the guide rail and slide it gently in the direction of the arrow.
  5. Push the lower part of the drive until it reaches the position where the hook on the handle engages with the square hole on the frame.
  6. With the stopper toward you, raise the stopper and press it to disengage the lock. If the handle is raised so the hook of the handle cannot enter into each hole, the drive cannot be installed properly because it is blocked by the frame of the storage system.

  7. Gently pull the handle of the drive toward you, to make sure the drive is installed securely.
  8. Confirm that the red ALM LED is off at the new drive.
  9. In the maintenance utility, click Hardware > Controller Chassis or Hardware > Drive Box.
  10. Click the Drives tab, and then confirm that the status of the drive to be replaced is Normal. If necessary, click Refresh at the top-right of the window to update the status in the window.
  11. Attach the front bezel.

Check the drive status

 

  1. In the maintenance utility, click Hardware > Controller Chassis or Hardware > Drive Box.
  2. Click the Drives tab.
  3. Confirm that the status of the replacement drive is Normal.
  4. Perform the appropriate next step:

If you replaced a drive without blocking it, click Refresh at the top-right of the Maintenance Utility window to update the window, and then check the status of the replaced drive.

If you replaced the drive after saving data to a spare drive, the drive status changes to Normal after performing the copy-back operation. This operation can take up to 12 hours to perform, depending on the configuration and drive capacity.

If the drive status is Copy incomplete, the correction-copy operation cannot be performed because a copy-processing operation is being performed in the parity group to which the target drive belongs. Complete the other copy-processing operation, and then replace the drive.

If the drive status is Reserved, the copy-back operation cannot be performed because more than one copy-processing operation is being performed in the parity group to which the copy-back source drive of the target drive belongs. Complete the other copy-processing operation, and then replace the drive.

If the copy-back operation is set to disabled, this operation will not be performed.
