Configuration: Disk Groups and Virtual Disks

After you have created a security key, you can create secure disk groups from 

security capable physical disks. Creating a secure disk group makes the 

physical disks in the disk group security-enabled. Security-enabled physical 

disks enter Security Locked status whenever power is re-applied. They can be 

unlocked only by a RAID controller module that supplies the correct key 

during physical disk initialization. Otherwise, the physical disks remain 

locked, and the data is inaccessible. The Security Locked status prevents any 

unauthorized person from accessing data on a security-enabled physical disk 

by physically removing the physical disk and installing the physical disk in 

another computer or storage array.

When you change a security key, a new security key is generated by the 

system. The new key replaces the previous key. You cannot view or read the 

key. However, a copy of the security key must be kept on some other storage 

medium for backup in case of system failure or for transfer to another storage 

array. A pass phrase that you provide encrypts and decrypts the security key 

for storage on other media.
When you change a security key, you also provide information to create a 

security key identifier.
Changing the security key does not destroy any data. You can change the 

security key at any time. 
Before you change the security key, ensure that:

• All virtual disks in the storage array are in Optimal status.
• In storage arrays with two RAID controller modules, both are present and 

working normally.

To change the security key:

1 In the AMW toolbar, select Storage ArrayPhysical Disk Security 

Change Security Key. 
The Confirm Change Security Key window is displayed.

2 Type yes in the text field, and click OK.

The 

Change Security Key window is displayed.
