NOTE: Patrol read mode operations such as Start and Stop are not supported if there are no
virtual disks available in the controller. Though you can invoke the operations successfully using
the iDRAC interfaces, the operations will fail when the associated job is started.
• To specify the Check Consistency Mode, use Storage.Controller.CheckConsistencyMode object.
• To enable or disable the Copyback Mode, use Storage.Controller.CopybackMode object.
• To enable or disable the Load Balance Mode, use Storage.Controller.PossibleloadBalancedMode
object.
• To specify the percentage of the system's resources dedicated to perform a check consistency on a
redundant virtual disk, use Storage.Controller.CheckConsistencyRate object.
• To specify the percentage of the controller's resources dedicated to rebuild a failed disk, use
Storage.Controller.RebuildRate object
• To specify the percentage of the controller's resources dedicated to perform the background
initialization (BGI) of a virtual disk after it is created,
useStorage.Controller.BackgroundInitializationRate object
• To specify the percentage of the controller's resources dedicated to reconstruct a disk group after
adding a physical disk or changing the RAID level of a virtual disk residing on the disk group, use
Storage.Controller.ReconstructRate object
• To enable or disable the enhanced auto import of foreign configuration for the controller, use
Storage.Controller.EnhancedAutoImportForeignConfig object
• To create, modify, or delete security key to encrypt virtual drives:

Importing or auto importing foreign configuration
A foreign configuration is data residing on physical disks that have been moved from one controller to
another. Virtual disks residing on physical disks that have been moved are considered to be a foreign
configuration.
You can import foreign configurations so that virtual disks are not lost after moving Physical Disks. A
foreign configuration can be imported only if it contains a virtual disk that is in either Ready or Degraded
state or a hotspare that is dedicated to a virtual disk which can be imported or is already present.
All of the virtual disk data must be present, but if the virtual disk is using a redundant RAID level, the
additional redundant data is not required.
For example, if the foreign configuration contains only one side of a mirror in a RAID 1 virtual disk, then
the virtual disk is in a Degraded state and can be imported. If the foreign configuration contains only one
physical disk that was originally configured as a RAID 5 using three physical disks, then the RAID 5 virtual
disk is in a Failed state and cannot be imported.
In addition to virtual disks, a foreign configuration may consist of a physical disk that was assigned as a
hot spare on one controller and then moved to another controller. The Import Foreign Configuration task
imports the new physical disk as a hot spare. If the physical disk was set as a dedicated hot spare on the
