Recovering a RAID Group

RAID recovery enables you to recover a RAID group in the event of accidental disk removal or SATA connector failure. When several disks are removed or disconnected from a RAID group:

  • The status of the group changes to Error.

  • The statuses of all storage pools using the RAID group change to Inactive.

  • All data on shared folders and LUNs in affected storage pools becomes inaccessible.


RAID recovery only helps when disks are temporarily disconnected and then reconnected. It does not help in the event of disk failure.

  1. Reconnect all disconnected disks.

    Ensure that each disk is reinserted into its original drive bay.

  2. Go to Storage & Snapshots > Storage > Storage/Snapshots.
  3. Select a storage pool with the status Inactive.
  4. Click Manage.

    The Storage Pool Management window opens.

  5. Select a RAID group with the status Error.
  6. Click Manage, and then select Recover RAID.

QuTS hero starts to rebuild the RAID group.
