Configuring a RAID Group Hot Spare

Assigning a hot spare gives extra protection against data loss. In normal conditions, a hot spare disk is unused and does not store any data. When a disk in the RAID group fails, the hot spare disk automatically replaces the faulty disk. QTS copies the data to the spare disk in a process called RAID rebuilding.

  1. Verify that the NAS contains one or more free disks.
  2. Go to Storage & Snapshots > Storage > Storage/Snapshots.
  3. Select a storage pool or single static volume.
  4. Click Manage.
  5. Select a RAID 1, RAID, 5, RAID 6, or RAID 10 group.
  6. SelectManage > Configure Spare Disk.
  7. Select one or more disks.
    Warning:

    All data on the selected disks will be deleted.

  8. Click Apply.

    A confirmation message appears.

  9. Click OK.

The spare disks are added to the RAID group. The disk appears as a green Spare in the disks summary at Disks/VJBOD.
