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 conguration for the controller, use
Storage.Controller.EnhancedAutoImportForeignCong object
• To create, modify, or delete security key to encrypt virtual drives:
racadm storage createsecuritykey:<Controller FQDD> -key <Key id> -passwd <passphrase>
racadm storage modifysecuritykey:<Controller FQDD> -key <key id> -oldpasswd <old passphrase> -
newpasswd <new passphrase>
racadm storage deletesecuritykey:<Controller FQDD>
Importing or auto importing foreign conguration
A foreign conguration 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 conguration.
You can import foreign congurations so that virtual disks are not lost after moving Physical Disks. A foreign conguration 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 conguration 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 conguration contains only one physical disk that was originally congured 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 conguration 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 Conguration task imports the new physical disk as a hot spare. If the physical disk was
set as a dedicated hot spare on the previous controller, but the virtual disk to which the hot spare was assigned is no longer present in the
foreign conguration, then the physical disk is imported as a global hot spare.
If any foreign congurations locked using Local Key manager (LKM) are Detected, then import foreign conguration operation is not
possible in iDRAC in this release. You must unlock the drives through CTRL-R and then continue to import foreign conguration from
iDRAC.
The Import Foreign Conguration task is only displayed when the controller has detected a foreign conguration. You can also identify
whether a physical disk contains a foreign conguration (virtual disk or hot spare) by checking the physical disk state. If the physical disk
state is Foreign, then the physical disk contains all or some portion of a virtual disk or has a hot spare assignment.
NOTE
: The task of importing foreign conguration imports all virtual disks residing on physical disks that have been added to the
controller. If more than one foreign virtual disk is present, all the congurations are imported.
