Importing Or Recovering Foreign Configurations
The recover operation attempts to restore degraded, failed, or missing virtual disks to a healthy state. A virtual disk may be in a degraded, failed, or missing state after losing communication with the controller due to a power loss, faulty cable connection, or other failure. A rebuild or background initialization may automatically initiate after the recover operation completes.
The virtual disk data may be inconsistent after recovery. Verify the virtual disk data after the Import/Recover Foreign Configuration task completes.
In some cases, the virtual disk data is incomplete and it is not possible to successfully recover the virtual disk.
To import or recover a foreign configuration:
Click Import/Recover to import or recover all virtual disks residing on physical disks attached to the controller.
To exit without importing or recovering the foreign configuration, click Cancel.
