Goal

Replace a failed drive in a ST5320 NAS CU(Controller Unit) or EU(Expansion Unit) disk tray.

Solution

The following sections describes how to replace a failed disk drive in a ST5320 NAS CU(Controller Unit) or EU(Expansion Unit) disk tray.

Tools and Equipment:
Antistatic protection
Replacement drive

Be sure to consider the following cautions.

Caution - Mixed configurations speed requirements. In configurations involving various models of EUs, or drive modules, all modules must be operating at the same speed. Refer to the Product Release Notes for any model-specific restrictions.

Caution - Risk of data loss and permanent damage. Magnetic fields can destroy all data on a disk drive and cause irreparable damage to its circuitry. To prevent data loss and damage to disk drives, always keep drive modules and drives away from magnetic devices.

To replace a drive in a ST5320 NAS CU(Controller Unit) or EU(Expansion Unit):

1. Locate failed drive with the RAID Management menu in the Web Admin.

Caution - Electrostatic discharge damage to sensitive components. To prevent electrostatic discharge damage to the module, use proper antistatic protection when handling the module components.

2. Put on antistatic protection.

Caution - Potential damage to drives. Bumping disk drives against another surface can damage the drive mechanism or connectors. To prevent damage when removing or installing a drive, always place your hand under the drive to support its weight

3. Unpack the new drive.
Set the new drive on a dry, level surface, away from magnetic fields. Save all packing materials in case you need to return the drive.

Caution - Potential data loss. Removing a drive that has not failed can cause data loss. To prevent data loss, remove only a failed drive that has a fault (amber) light on or that are otherwise certain has failed.

4. Check the Fault lights on the front of the module. If a fault is detected, the amber fault light is on.

Caution - Be very careful to remove only the drive with the fault indication. If you remove an active drive accidentally, wait 30 seconds and then reinstall it. Check the RAID management menu in Web Admin to verify that there are no failed LUNs. If a LUN has failed due to the unexpected drive removal, STOP immediately and escalate the issue.

5. Lift the locking lever and remove the failed drive.

6. Wait 30 seconds for the operating system to recognize that the drive has been removed.

7. Slide the new drive all the way into the empty slot and close the drive lever.
As the drive spins up, the fault light can flash intermittently. A flashing active light indicates that data is being restored to the new drive.

8. Choose one of the following steps, based on the status of the Active and Fault lights:

* Active (OK) light is off
The drive might be installed incorrectly. Remove the drive, wait 30 seconds, and then reinstall it. When finished, go to Step 9.

* Fault (Service Required) light is illuminated
The new drive might be defective. Use another new drive to repeat this procedure.

Is the problem corrected?
Yes - Go to Step 9.
No - Contact technical support.

* Active lights are on and Fault lights are off.
Go to Step 9.

9. Remove the antistatic protection.

Procedure is from the ST5320 Trouble Shooting Guide, 819-4285
