Rekey Encryption

Caution: Hewlett Packard Enterprise strongly recommends that you back up the authentication key and save the backup key file to a secure location. If there is an unforeseen event and you cannot use the backup file and its password, you will be at risk of losing all of your data.

Tip: In environments with multiple storage systems, Hewlett Packard Enterprise recommends that you use unique file names that can be associated with each encrypted storage system.

When you have completed your choices, click Rekey to start the action and close the dialog.
