Abstract
A computer program product includes computer readable program code for initiating boot of a multi-node system including a first compute node scaled together with a second compute node, wherein the multi-node system boots from a basic input output system of the first compute node that is identified as a primary node by a trusted platform module of the first compute node. The computer program product further comprises computer readable program code for receiving a request to reconfigure the multi-node system so that the second compute node would become the primary node, and computer readable program code for reconfiguring the multi-node system so that the second node is the primary mode only in response to a user manually asserting physical presence to a trusted platform module of the first compute node.
