Set Storage Array Security Key - Dell PowerVault MD3220 Cli Manual

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.
