Transition of drives from local key management to enterprise key management (without supported firmware for PERC and iDRAC)

Local key management drives can be transitioned to an enterprise key management enabled system, but the controller cannot be transitioned from local key management mode to enterprise key manager mode or the reverse without first disabling security on the controller. Perform the following steps to transition from local key management drives to enterprise key management:

1. Save the current local key management security key.
2. Shut down both systems.
3. Remove the local key management drives and reinsert them to the enterprise key manager enabled system.
4. Power on the enterprise key manager system.
5. Go to HII foreign configuration.
6. Enter the local key management keys for those drives.
7. Import the configuration.
   NOTE:Once local key management drives are migrated to enterprise key manager, they cannot be migrated back to local key management mode. The drives have to be cryptographically erased to disable security and then converted back to local key management disks.
