Abstract
The disclosed embodiments relate to systems and methods for coordinating management of a shared disk storage between nodes. Particularly, a messaging protocol may be used to communicate notifications regarding each node's perception of the shared storage's state. The nodes may use the messaging protocol to achieve consensus when recovering from a storage device failure. Some embodiments provide for recovery when localized failures, such as failures at an adapter on a node, occur.
