Recovering a RAID Group with an Error Status

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 volumes and storage pools using the RAID group change to Inactive.

  • All data on the affected volumes and LUNs 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 or single static volume with the status Inactive.
  4. Click Manage.

    The Storage Pool Management or Volume Management window opens.

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

QTS starts to rebuild the RAID group.
