Security Key and RAID Management 129Failure to Select or Configure Non Self-Encrypting Disks (non-SED)A virtual disk can be either secured or unsecured depending on how it wasconfigured when created. In order to create a secured virtual disk, thecontroller must have a security key present and must be composed of SEDsonly. In order to select/configure non-SED, you must create an unsecuredvirtual disk. You can create an unsecured virtual disk even if there is a securitykey present. Select the secure virtual disk option as No in the Create New VDmenu. See "Creating Virtual Disks" on page 88 for steps on how to create anunsecured virtual disk.Failure to Delete Security KeyA security key is used to lock or unlock access to a security-enabledcomponent. This key is not utilized in the actual encryption of data. If asecurity key is present, both secured and unsecured virtual disks may exist.To delete the security key, you must have a previously established security keypresent on the controller and there can not be any configured secured disks.If there are configured secured disks, remove or delete them.Failure to Instant Secure Erase Task on Physical DisksInstant Secure Erase is the process of securely erasing all data permanently onan encryption-capable physical disk and resetting the security attributes. It isused in a couple of scenarios such as deleting a foreign configuration in theevent of a forgotten or lost passphrase or unlocking a disk that had beenpreviously locked.Instant Secure Erase can be executed only on encryption-capable disks as longas the disks are not hot spares and are not configured (not part of a virtualdisk). Ensure that the conditions are met and see "Instant Secure Erase" onpage 128.
