The NA
S supports hot-swapping the hard drives when 1 member drive crashes in
RAID 1, 1–2 member drives crash in RAID 5 or RAID 6. Follow the steps below to
hot-swap the hard drive when a member drive fails in a RAID configuration.
1. Login the NAS and check the disk volume configuration in “Volume
Management”.
2. The volume status should be “in degraded mode”.
3. Prepare a new hard drive to replace the failed one. The capacity of the new
hard drive should be the same as or larger than the failed hard drive.
4. Unplug the failed drive from the NAS. Wait for about 20 seconds or until the
server beeps twice.
5. Remove the failed drive from the drive tray.
6. Install the new hard drive on the drive tray. Insert it to the NAS.
7. The server should beep 1.5 seconds twice.
8. Check the volume status on the web administration page. The volume should
be rebuilding.
Warning: You are strongly recommended to turn OFF the server before
replacing the HDD to reduce the risk of electric shock.
