Abstract
A method of restoring data coherency is disclosed, whereby a duplex shared memory subsystem quickly recovers from a failure of one of the duplexed memory pair. A cluster first divides the duplex shared memory subsystem into segments each of which is a unit for copying. After synchronizing itself with other operating clusters, the cluster initiates a coherency restoration process to be performed in cooperation with all other operating clusters, sharing the jobs related to the segments. This results in reducing the time required for the coherency restoration process where the system must operate in an unreliable, coherency-lacking situation.
