Lost or forgotten Master Key

IMPORTANT: HP strongly recommends storing a backup of the Master Encryption Key in a secure location. In some instances it is possible that a missing key will render your data inaccessible. If operating HP Secure Encryption in Remote Key Management Mode, HP strongly recommends that you back up the ESKM regularly.

Local mode

If operating HP Secure Encryption in Local Mode, securing the Master Encryption Key value is critical to accessing the encrypted logical drive data. If the controller requires replacement or if the physical drives are moved to another controller, a matching Master Key is required to gain access to the data. Master Keys are not recoverable if lost. If the Master Key is lost or forgotten, you must perform a data restore operation from the backup media to regain access to the data.

Remote mode

Locating the key using the HP ESKM

To locate a lost or forgotten Master Encryption Key using the HP ESKM:

1.Log in to the HP ESKM ("Logging in to the HP ESKM" on page 18).
