| Partially optimal virtual disk | One or more physical disks in the virtual disk have failed and reduced the fault tolerance of the virtual disk. The virtual disk is still operating normally. |
| Partially optimal virtual disk with background activity | The partially optimal virtual disk is performing a background activity. |
| Degraded virtual disk | The virtual disk is degraded and has no fault tolerance. In this state, data is not recoverable if one physical disk fails. Rebuild the virtual disk by replacing the failed physical disks. |
| Degraded virtual disk with background activity | The degraded virtual disk is rebuilding. |
