After you have created a security key, you can create secure disk groups from security capable physical disks. Creatinga secure disk group makes the physical disks in the disk group security enabled. Security enabled physical disks enterSecurity Locked status whenever power is re-applied. They can be unlocked only by a RAID controller module thatsupplies the correct key during physical disk initialization. Otherwise, the physical disks remain locked, and the data isinaccessible. The Security Locked status prevents any unauthorized person from accessing data on a security enabledphysical disk by physically removing the physical disk and installing the physical disk in another computer or storagearray.Changing A Security KeyWhen you change a security key, a new security key is generated by the system. The new key replaces the previouskey. You cannot view or read the key. However, a copy of the security key must be kept on some other storage mediumfor backup in case of system failure or for transfer to another storage array. A pass phrase that you provide encryptsand decrypts the security key for storage on other media. When you change a security key, you also provide informationto create a security key identifier. Changing the security key does not destroy any data. You can change the security keyat 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.
