1. Administration in web interface
You can view the state of the RAID in the web interface of your device. To do this, select the item RAID setup in the main menu of the web interface. This screen also gives you the option to repair the RAID if necessary.
2. Exchanging a defective hard drive
If a hard drive is detected as being defective, this will be displayed in the web interface with defective. On the actual device, depending on the nature of the error, this will be shown by a blue flashing LED at the hard drive bay.
Moving the small lever on the left-hand side of the bay will unlock the fixing mechanism, enabling you to pull the frame out of the housing together with the hard drive. You can now loosen the screws on the underside of the frame and remove the defective hard drive. Now mount the new hard drive into the frame and push the frame back into the free bay of the device.
If the device is switched on while you are exchanging the hard drive, the RAID rebuild will start automatically. You can view the progress in the web interface.
Failsafe operation is only restored once the RAID has been completely repaired.
3. Both hard drives defective
If the device detects that both hard drives are defective or have been removed from the device, a restart is automatically triggered.
