Abstract:
A method and system for the automatic data recovery for a duplex pair is provided. The preferred embodiment includes the discovery of lost data on the first subsystem. A copy of the lost data is automatically transferred from the second subsystem to the first subsystem. Then the copy of the lost data is automatically written into the first subsystem. The host processor and the operator is unaware data had been lost. The method and system of the present invention eliminates the need to terminate the job which triggered the discovery of the lost data. It also eliminates the need for any involvement of the operator in the data recovery process.
