Unlock Foreign
Configuration
racadm storage unlock:<Controller FQDD> -key
<Key id> -passwd <passphrase>
This feature is used to authenticate locked
drives which have a different source
controller encryption than the destination.
Once unlocked, the drive can be successfully
migrated from one controller to another.
Import Foreign
Configuration
racadm storage
importconfig:RAID.Integrated.1-1
After a successful unlock the drives are still
secured by the foreign controller key. Running
the import feature changes the key on these
drives with the local controller and the
security status changes from Foreign to
Secured.

Patrol read mode considerations
Patrol read identifies disk errors to avoid disk failures, data loss, or corruption. It runs automatically once a week on SAS and SATA HDDs.
The Patrol Read does not run on a physical disk in the following circumstances:
• The physical disk is an SSD.
• The physical disk is not included in a virtual disk or assigned as a hot spare.
• The physical disk is included in a virtual disk that is undergoing one of the following:
• A rebuild
• A reconfiguration or reconstruction
• A background initialization
• A check consistency
In addition, the Patrol Read operation suspends during heavy I/O activity and resumes when the I/O is complete.
NOTE:
For more information on how often the Patrol Read operation runs when in auto mode, see the respective
controller documentation.
