Abstract
Storage media is coupled to first and second storage controllers. When the first storage controller performs encryption key rotation, the first storage controller writes a key rotation message to a storage controller metadata section of the storage media indicating that key rotation is underway. The second storage controller observes the key rotation message indicating that key rotation is underway and suspends access by the second storage controller to encrypted portions of the storage media.
