About RAID 1
RAID 1 disk mirroring provides highly secure data protection. You can use two hard drives of the same capacity to create a RAID 1 array. The RAID 1 creates an exact copy of data on the member drives. RAID 1 protects data against single drive failure. The usable capacity of RAID 1 is the capacity of the smallest member drive. It is particularly suitable for personal or company use for important data saving.
Logical volume status when RAID 1 operates normally
When RAID 1 operates normally, the volume status is shown as Ready in the Current Disk Volume Configuration section.
When a drive fails, follow the steps below to check the drive status:
- The server beeps for 1.5 sec twice when the drive fails.
- The Status LED flashes red continuously.
- Check the Current Disk Volume Configuration section. The volume status is In degraded mode.
- You can check the error and warning messages for drive failure and disk volume in degraded mode respectively in the Event Logs.
Note: You can send and receive alert e-mail by configuring the alert notification. For the settings, please refer to the System Settings/ Alert Notification section in the user manual.
Install a new drive to rebuild RAID 1 by hot swapping
Please follow the steps below to hot swap the failed hard drive:
- Prepare a new hard drive to rebuild RAID 1. The capacity of the new drive should be at least the same as that of the failed drive.
- Insert the drive to the drive slot of the server. The server beeps for 1.5 seconds twice. The Status LED flashes red and green alternatively.
- Check the Current Disk Volume Configuration section. The volume status is Rebuilding and the progress is shown.
- When the rebuilding is completed, the Status LED lights in green and the volume status is Ready. RAID 1 mirroring protection is now active.
- You can check the disk volume information in the Event Logs.
Note: Do not install the new drive when the system is not yet in degraded mode to avoid unexpected system failure.
