When a power failure of a volatile first storage occurs, an apparatus detects the power failure, and writes backup target data in a non-volatile second storage. When an abnormality of the first storage occurs, the apparatus detects the abnormality, acquires second information including a hardware state at a time when the abnormality is detected, and writes the first information and the second information in the second storage. When an abnormality occurs during the writing the backup target data, the apparatus suspends the writing the backup target data, acquires the second information, and writes backup data and the second information in the second storage, where the backup data is the backup target data that has not been written to the second storage.

Storage control device with power failure processing and abnormality processing

An information processing apparatus manages activation of a program by a task which is a unit of execution, and executes a task for each sequence in units of process block. The information processing apparatus has a nonvolatile memory which keeps an execution state management table. The execution state of the process block is stored in the execution state management table. The control unit performs a first activation procedure which initializes the execution state management table and, while updating the execution state in the execution state management table, executes the task. When activation by the first activation procedure has failed, the control unit performs activation by a second activation procedure and identifies a suspicious sequence. When activation by the second activation procedure has failed, the control unit performs activation by a third activation procedure and identifies a suspicious task.
