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.
