Abstract
The invention provides a method and system in which a node in a 2-node high availability cluster can declare itself impaired. In doing so, an impaired node can self diagnose or request another node in the cluster assist in diagnosing the problem. An impaired node can then request another node takeover the impaired node's tasks whereby the impaired node is able to shut down gracefully.
