DYNAMIC REPLICA VOLUME SWAP IN A CLUSTER

摘要

A method, system, and article are provided to enable a dynamic replica volume swap operation in a clustered computer system. Each node in the system is configured with flash memory, with a hierarchical list of boot volumes therein. Following a dynamic replica volume swap operation, the current boot volume is communicated to each node in the cluster and each node joining the cluster. All previously inactive nodes that were booted from the improper boot volume are re-booted from the correct one and the flash memory is amended to reflect the correct boot volume.
