Abstract
Method, apparatus and computer program product are provided for operating a plurality of computer nodes while maintaining trust. A primary computer node and at least one secondary computer node are connected into a cluster, wherein each of the clustered computer nodes includes a trusted platform module (TPM) that is accessible to software and includes security status information about the respective computer node. Each clustered computer node is then merged into a single node with only the TPM of the primary computer node being accessible to software. The TPM of the primary computer node is updated to include the security status information of each TPM in the cluster. Preferably, the step of merging is controlled by power on self test (POST) basic input output system (BIOS) code associated with a boot processor in the primary node.
