Configuring an Enclosure Spare Disk

An enclosure space disk acts as a hot spare for all RAID groups within a single enclosure (NAS or expansion unit). Under normal conditions, the enclosure space disk is unused and does not store any data. When a disk in any RAID group fails, the hot spare disk automatically replaces the faulty disk.

Important:

Storage enclosures (the NAS and expansion units) cannot share enclosure space disks. A unique spare disk must be assigned to each storage enclosure.

  1. Go to Storage & Snapshots > Storage > Disks/VJBOD
  2. Optional: Select a connected expansion unit.
  3. Select a free disk.
    Warning:

    All data on the selected disk will be deleted.

  4. Click Action, and then select Set as Enclosure Spare.

    A confirmation message appears.

  5. Click OK.

The disk appears as a Spare on the Disks/VJBOD screen.
