Users Guide

While running the unlock command, provide the source controller passphrase and key ID for these drives. Even after unlocking,
the ‘foreign controller key’ still secures these drives. However, you can see these drives while searching for foreign drives in the
existing ‘preview foreign config’. You can import or clear the foreign configuration on these secure drives.
If foreign drives with different security keys are migrated from more than one controller, then unlock and import or clear the
set of drives from one foreign controller before unlocking the drives migrated from another controller. This action ensures that
unlock is not allowed on a controller, if the controller has drives that are unlocked but not imported or cleared.
Once drives are unlocked, you can import the foreign configuration using the CMC web interface or RACADM.
If the controller is power cycled after the unlock and before the import phase, the drives are locked again.
If the system has multiple foreign configurations, unlock and import each foreign configuration before unlocking the foreign
configuration.
The key ID used in unlocking is used only to identify the drives with matching the key ID. After the matching drives are found,
the passphrase is used for unlocking the drives.
Unlocking Foreign Configuration Using CMC Web Interface
To unlock the foreign configuration:
1. In the left pane, click Chassis Overview > Storage > Controllers > Setup.
2. Navigate to the Setup page.
3. Click Click here to Unlock.
The Physical Disks page is displayed.
4. Select the physical disks that you want to unlock.
5. Check if the Physical disk is associated with the key identifier.
6. From the Actions drop-down, select Unlock Drive.
A dialogue box is displayed prompting you to enter the security key phrase.
7. Enter a passphrase in the Security Key Passphrase text box.
8. Re-enter the passphrase and click Unlock.
The physical drive is unlocked and the drive does not appear in the Recover Physical Disks list.
Unlocking Foreign Configuration Using RACADM
To unlock foreign configuration by running a RACADM command, use the following syntax:
racadm raid unlock:<Controller FQDD> -key <Key id> -passwd <passphrase>
For more information, see the Chassis Management Controller PowerEdge VRTX RACADM Command Line Reference Guide.
Cryptographic Erase
You can use the cryptographic erase option to securely erase data present on secure SEDs. Secure data exists on drives even
after the virtual disk is deleted and is thus exposed to threat. Cryptographic erase can be used in the following conditions:
● To erase data to retire/reuse secure drives.
● To securely erase data if secure and locked foreign configuration need not be imported.
● To recover locked drives if the passphrase is lost.
You can perform the cryptographic erase on one or more SED physical disks.
CAUTION: Performing the cryptographic erase task erases all data on the physical disk.
Performing Cryptographic Erase
If the physical disk is part of a virtual disk, remove it from the virtual disk before performing cryptographic erase.
To perform a cryptographic erase:
1. In the left pane, go to Storage > Physical Disks > Setup.
