QNAP Turbo NAS TVS-1271U-RP, Hardware User Manual

Page: 31 / 51

The NAS supports hot-swapping the hard drives when 1 member drive crashes in RAID 1 or
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 storage pool status in “Storage Manager” > “Storage
Pools”.
2. The storage pool status should be “Warning” and RAID group status should be
“Degraded”.
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: Users are strongly recommended to turn OFF the server before replacing
the hard drive to reduce the risk of electric shock.
