Set Storage Array Security Key Use this command to set the security key that is used throughout the storage array to implement the Physical Disk Security premium feature. When any security-capable physical disk in the storage array is assigned to a secured disk group, that physical disk is security-enabled using the security key. Before you can set the security key, you must use the create storageArray securityKey command to create the security key. Syntax set storageArray securityKey Parameters None. Additional Information Security-capable physical disks have hardware to accelerate cryptographic processing and each has a unique physical disk key. A security-capable physical disk behaves like any other physical disk until it is added to a secured disk group. When a security-capable physical disk is added to a secured disk group, it becomes security-enabled. Whenever a security-enabled physical disk is powered on, it requires the correct security key from the RAID controller module before it can read or write data. So, a security-enabled physical disk uses two keys: the physical disk key that encrypts and decrypts the data and the security key that authorizes the encryption and decryption processes. The set storageArray securityKey command commits the security key to all of the RAID controller modules and security-enabled physical disks in the storage array. The self encrypting disk feature ensures that if a security-enabled physical disk is physically removed from a storage array, its data cannot be read by any other device unless the security key is known. 216 Script Commands
