Abstract
Exemplary methods, systems, and computer program product embodiments for synchronizing a swappable module between modular computer systems are provided. Each of the embodiments has dual controllers and distributed copies of states. Upon an insertion of the swappable module in a storage system, a plurality of storage components are queried, including a partner swappable module, to determine if a quorum of identification information is present. If the quorum is present, at least one of the plurality of storage components having non-matching identification information is overwritten with the identification information of the quorum. If the quorum is not present, a reset to default procedure is performed. The reset to default procedure designates at least as many storage components of the plurality of storage components with the identification information sufficient to constitute the quorum.
