A method and system for method of removing a node from a multi-node
computer. The node receives a system management interrupt (SMI),
resulting in a quiescenting of only that node. The SMI receiving node
then polls other nodes in the multi-node computer to determine if the SMI
affects an operation of any of the other nodes, and quiescents any other
node affected by the SMI. Each quiescent node then transfers all of the
contents of its system memory to a backup memory in an unaffected remote
node in the multi-node computer. The remote node than assumes the
function of the removed node that had received the SMI. The method and
system thus allows node removal in the event of a hot-swap request or a
predicted failure of a node.
