The pass phrase that you enter is masked.

NOTE:

Create Key is active only if the pass phrase meets the above

mentioned criterion.

5 In Confirm pass phrase, re-enter the exact string that you entered in Pass

phrase.
Make a record of the pass phrase that you entered and the security key

identifier that is associated with the pass phrase. You need this

information for later secure operations.

6 Click Create Key.
7 Make a record of the security key identifier and the file name from the

Create Security Key Complete dialog, and click OK.

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.

Changing a Security Key

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.
