2. Click Main Menu > Configuration Management > Manage Foreign Configurations.
3. Click Enter Passphrase for Locked Disks.
A screen is displayed asking if you are sure you want to perform the operation.
4. Enter Passphrase if importing non-RAID disk with a different passphrase.
5. Select the Confirm option.
6. Click Yes.
NOTE: If Auto-Configure for non-RAID Disks is enabled, the disk becomes a non-RAID disk. Else, it is unconfigured.
Import a secured virtual disk
Prerequisites
NOTE: The controller must have an existing security key before importing secured foreign virtual disk.
Steps
1. Enter the Dell PERC 11 Configuration Utility. See Navigate to Dell PERC 11 configuration utility.
2. Click Main Menu > Configuration Management > Manage Foreign Configurations > Preview Foreign
Configurations.
3. Click Import Foreign Configuration.
A screen is displayed asking if you are sure you want to perform the operation.
4. Enter Passphrase if importing virtual disk with a different passphrase.
5. Select the Confirm option.
6. Click Yes.
The foreign configuration is imported successfully.
Dell Technologies OpenManage Secure Enterprise Key
Manager
This feature allows the PERC to receive a security key from a remote server instead of saving the key on a local controller. This
protects data on secured disks under the PERC if the disks or entire system is stolen. Refer to the www.dell.com/idracmanuals
for more information on configuring OpenManage Secure Enterprise Key Manager, as well as Secure Sockets Layer (SSL) or
Transport Layer Security (TLS) related configuration.
NOTE:
Downgrade of PERC firmware to a firmware that does not support enterprise key management while enterprise key
manager mode is enabled, is blocked.
NOTE: When replacing a controller enabled with enterprise key management, lifecycle controller part replacement will
re-configure the new controller to match the existing controller's configuration.
NOTE: If key exchange fails during boot, view and correct any connection issues with the key server identified in the iDRAC
lifecycle log. Then the system can be cold booted.
Supported controllers for OpenManage Secure Enterprise Key
Manager
Enterprise key manager mode is supported on the PERC H755 adapter, PERC H755 front SAS, and PERC H755N front
NVMe, and allows the creation of secured virtual disks and non–RAID disks. For more information on supported platforms, see
www.dell.com/idracmanuals.
