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.

Important:

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.
    Important:

    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.
