Set Storage Array Security Key
Description
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.
Set Storage Array Time
Description
This command sets the clocks on both RAID controller modules in a storage array by synchronizing the RAID controller
module clocks with the clock of the host from which you run this command.
Syntax
set storageArray time
Parameters
None.
