Changing 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 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 menu bar, select Storage Array > Security > Physical Disk Security > Change 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.
  3. In Secure key identifier, enter a string that become part of the secure key identifier.
    You may leave the text box blank, or enter up to 189 alphanumeric characters without white space, punctuation, or symbols. Additional characters is generated automatically.
  4. 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.
  5. 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 nonalphanumeric character—for example, < > @ +.

    The pass phrase that you enter is masked.

  6. In Confirm pass phrase, re-enter the exact string you entered in Pass phrase.
    Make a record of the pass phrase you entered and the security key identifier it is associated with. You need this information for later secure operations.
  7. Click Change Key.
  8. Make a record of the security key identifier and the file name from the Change Security Key Complete dialog, and click OK.
