Failure of Cryptographic Erase on encryption-capable 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 scenarios such as deleting a foreign configuration in the event of a forgotten or lost passphrase or unlocking a disk that had been previously locked.

You can perform Cryptographic Erase only on encryption-capable disks that are not hot spares and not configured as non-RAID or virtual disks. Ensure that the conditions are met and see Cryptographic Erase.
