Configuring a RAID Enclosure as an External Storage Device

Important:
  • The Mode switch on the RAID enclosure must be set to Software Control mode. For details, see the enclosure's hardware user guide.

  • The RAID enclosure must not contain any existing RAID groups.

Warning:

To prevent errors or data loss, do not change the enclosure Mode switch from Software Control to any other mode while the enclosure is connected to the NAS.

      Select this option to save a local copy of the encryption key on the NAS. This enables QTS to automatically unlock and mount the encrypted volume when the NAS starts up. If the encryption key is not saved, you must specify the encryption password each time the NAS restarts.

      Warning:
      • Saving the encryption key on the NAS can result in unauthorized data access if unauthorized personnel are able to physically access the NAS.

      • If you forget the encryption password, the volume will become inaccessible and all data will be lost.
