Abstract
A multi-node computer system is described which includes a number of active nodes and a standby node. Each node hosts a server installation. Each server has a system disk, and a recovery disk, which holds a synchronised recovery copy of data held on the system disk. In the event of failure of a node, a recovery process is run to reconfigure the system, by connecting the recovery disk corresponding to the failed computer to the system disk of the standby computer, and copying the contents of this recovery disk to the system disk. This causes the server in the failed node to migrate to the standby node, which thus becomes an active node.
