216 Script CommandsSet Storage Array Security KeyUse this command to set the security key that is used throughout the storagearray to implement the Physical Disk Security premium feature. When anysecurity-capable physical disk in the storage array is assigned to a secured diskgroup, that physical disk is security-enabled using the security key. Before youcan set the security key, you must use the create storageArray securityKeycommand to create the security key.Syntaxset storageArray securityKeyParametersNone.Additional InformationSecurity-capable physical disks have hardware to accelerate cryptographicprocessing and each has a unique physical disk key. A security-capablephysical disk behaves like any other physical disk until it is added to a secureddisk group. When a security-capable physical disk is added to a secured diskgroup, it becomes security-enabled.Whenever a security-enabled physical disk is powered on, it requires thecorrect security key from the RAID controller module before it can read orwrite data. So, a security-enabled physical disk uses two keys: the physical diskkey that encrypts and decrypts the data and the security key that authorizesthe encryption and decryption processes. The set storageArray securityKeycommand commits the security key to all of the RAID controller modules andsecurity-enabled physical disks in the storage array. The self encrypting diskfeature ensures that if a security-enabled physical disk is physically removedfrom a storage array, its data cannot be read by any other device unless thesecurity key is known.
