How do I set up two RAID 1 groups in TR-004?
Applicable Products
- TR-004
- QNAP External RAID Manager
Overview
The QNAP TR-004 is a 4-bay RAID expansion enclosure that supports multiple RAID configurations. When connected directly to a Windows PC or Mac OS, you can use the QNAP External RAID Manager utility to configure RAID groups. To set up two RAID 1 arrays, you must configure the device so that each pair of disks operates as a separate RAID 1 group.
Each RAID 1 array requires two disks. All data on the selected disks will be deleted during setup. The TR-004 must be set to Software Control mode to use the External RAID Manager.
Procedure
Important: Back up all important data before configuring or deleting RAID groups, as this process will erase all data on the selected disks.
- Set the TR-004 to Software Control mode.
- Ensure the mode switch on the rear of the TR-004 is set to Software Control before connecting it to your PC.
