Dell EMC H745P MX - Failure to Select or Configure Non Self-Encrypting Disks Non-SED; Failure to Delete Security Key; Failure of Cryptographic Erase Task on Secured Physical Disks; General Issues

• The secured virtual disk is in an oine state after supplying the correct passphrase—You must check to determine why the virtual
disk failed and correct the problem.
Failure to select or congure non Self-Encrypting Disks non-
SED
A virtual disk can be either secured or unsecured depending on how it was congured when created. In order to create a secured virtual
disk, the controller must have a security key present and must contain SEDs only. In order to select/congure non-SED, you must create an
unsecured virtual disk. You can create an unsecured virtual disk even if there is a security key. Select the Secure VD option as No in the
Create New VD menu. For steps on how to create an unsecured virtual disk, see Creating virtual disks.
Failure to delete security key
A security key is used to lock or unlock access to a security-enabled component. This key is not utilized in the actual encryption of data. If a
security key is present, both secured and unsecured virtual disks may exist.
To delete the security key, you must have a previously established security key present on the controller and there cannot be any
congured secured disks. If there are congured secured virtual disks, remove or delete them.
Failure of Cryptographic Erase task on secured physical disks
Cryptographic Erase is the process of securely erasing all data permanently on an encryption-capable physical disk and resetting the
security attributes. It is used in a couple of scenarios such as deleting a foreign conguration in the event of a forgotten or lost passphrase
or unlocking a disk that had been previously locked.
Cryptographic Erase can be executed only on encryption-capable disks as long as the disks are not hot spares and are not congured or
part of a virtual disk. Ensure that the conditions are met and see Cryptographic Erase.
