Hot-swap Hard Drives
The NAS supports hot-swapping hard drives if 1 member drive crashes in RAID 1 or 1–2
member drives crash in RAID 5 or RAID 6. Follow these steps to hot-swap hard drives if a
member drive fails in a RAID configuration.
1.
Log into 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 about 20 seconds or until the NAS beeps
twice.
5.
Remove the failed drive from the drive tray.
6.
Install the new hard drive on the drive tray. Insert it into the NAS.
7.
The server should beep for 1.5 seconds twice.
8.
Check the volume status on the web administration page. The volume should be
rebuilding.
Warning:
It is strongly recommended to turn off the NAS before replacing hard
drives to reduce the risk of electric shock.
