To save the security key for the storage array,
1. In the AMW toolbar, select Storage Array → Security → Physical Disk Security → Save Key.
The Save Security Key File - Enter Pass Phrase window is displayed.
2. Edit the default path by adding a file name to the end of the path or click Browse, navigate to the
required folder and enter the name of the file.
3. In Pass phrase, enter a string for the pass phrase.
The pass phrase must meet the following criteria:
– It must be between eight and 32 characters long.
– It must contain at least one uppercase letter.
– It must contain at least one lowercase letter.
– It must contain at least one number.
– It must contain at least one non-alphanumeric character (for example, < > @ +).
The pass phrase that you enter is masked.
4. In Confirm pass phrase, re-enter the exact string you entered in Pass phrase.
Make a record of the pass phrase you entered. You need it for later secure operations.
5. Click Save.
6. Make a record of the security key identifier and the file name from the Save Security Key Complete
dialog, and click OK.
Validate Security Key
A file in which a security key is stored is validated through the Validate Security Key dialog. To transfer,
archive, or back up the security key, the RAID controller module firmware encrypts (or wraps) the security
key and stores it in a file. You must provide a pass phrase and identify the corresponding file to decrypt
the file and recover the security key.
Data can be read from a security enabled physical disk only if a RAID controller module in the storage
array provides the correct security key. If security enabled physical disks are moved from one storage
array to another, the appropriate security key must also be imported to the new storage array. Otherwise,
the data on the security enabled physical disks that were moved is inaccessible.
See the online help topics for more information on validating the security key.
Unlocking Secure Physical Disks
You can export a security enabled disk group to move the associated physical disks to a different storage
array. After you install those physical disks in the new storage array, you must unlock the physical disks
before data can be read from or written to the physical disks. To unlock the physical disks, you must
supply the security key from the original storage array. The security key on the new storage array is
different and cannot unlock the physical disks.
You must supply the security key from a security key file that was saved on the original storage array. You
must provide the pass phrase that was used to encrypt the security key file to extract the security key
from this file.
For more information, see the online help topics.
Erasing Secure Physical Disks
In the AMW, when you select a security enabled physical disk that is not part of a disk group, the Secure
Erase menu item is enabled on the Physical Disk menu. You can use the secure erase procedure to re-
