Abstract:
1. A machine implemented method for a storage system having access to a storage device, comprising: configuring a first visual indicator for indicating that data is being transferred from a first memory to a second memory after a power failure of a primary power source of the storage system is detected; configuring a second visual indicator for indicating that the second memory has no data, after data is transferred from the second memory to the first memory, upon restoring power from the primary power source; detecting power failure from the primary power source of the storage system; using the first visual indicator for indicating a data transfer operation where data stored at the first memory is transferred to the second memory; transferring data from the first memory to the second memory using a secondary power source; storing any bit errors that occur while transferring data from the first memory to the second memory in a data structure; disabling the secondary power source upon transferring data from the first memory to the second memory; transferring data from the second memory to the first memory, after power from the primary power source is restored; using the second visual indicator to indicate that no data is stored at the second memory; and providing the data structure to a processor after the primary power source is restored to correct any bit error that occurred during transfer from the first memory to the second memory.
