Abstract
An apparatus, program product and method initiate a restart of a node in a clustered computer system using a member of a clustering group that resides on a different node from that to be restarted. Typically, a restart operation is initiated by the member in response to a membership change message sent by another group member that is resident on the node to be restarted, with an indicator associated with the membership change message that indicates that a restart should be initiated. Typically, the restart is implemented in much the same manner as a start operation that is performed when a node is initially added to a cluster, with additional functionality utilized to preclude repeated restart attempts upon a failure of a prior restart operation.
