摘要： A method, non-transitory computer readable medium, and apparatus that monitors an active virtual storage controller. A determination of when a failure of the active virtual storage controller has occurred is made based on the monitoring. When the failure of the active virtual storage controller is determined to have occurred, storage devices previously assigned to the active virtual storage controller are remapped to a passive virtual storage controller and transactions in a transaction log are replayed. In another example, active storage controllers are monitored with a passive storage controller. When a failure of one of the active storage controllers has occurred based on the monitoring is determined, storage devices previously assigned to the active storage controller are remapped, a transaction log associated with the active storage controller is retrieved from a transaction log database, and transactions in the transaction log are replayed.
