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.
  • Be mindful of other workers nearby.
  • Exercise care when removing or storing the dense intermix drive tray.
  • Do not pull out multiple dense intermix drive trays at one time because the rack can fall over.
  • Do not put objects on a dense intermix drive tray you removed from the rack.
  • Do not use the dense intermix drive tray as working space because the rack can fall over.

 

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 drive tray from the rack, remove the top cover, and then 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 is #0 to #59, from the bottom left to the top right.

  1. Pull up the stopper of the drive handle toward you to release the lock.
  2. Open the handle toward you, and then gently remove the drive to be replaced. Handle the drive with care.
  3. Place the drive into the guide rail and slide it gently in the direction of the arrow.
  4. Push the drive until a click indicates it has locked in place.

  5. Gently pull the handle of the drive toward you to make sure the drive is installed securely.
  6. In the maintenance utility, click Hardware > Controller Chassis or Hardware > Drive Box.
  7. 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.
  8. Confirm that the red ALM LED is off at the new drive.
  9. Attach the top cover of the dense intermix drive tray, and then return the drive tray to the rack.

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.
