Information processing apparatus, method of information processing, and recording medium having stored therein program for information processing

A method of processing information in an information processing apparatus comprising a plurality of processors each comprising a plurality of memories and a memory controller that controls the plurality of memories, the method comprising:

• checking whether the plurality of processors operate normally when the information processing apparatus is started;
• finding any failed processor on the basis of a result of the checking;
• falling back a failed processor if any;
• determining whether the plurality of memories are used in a redundancy configuration that makes the plurality of memories redundant;
• determining that determines, when the plurality of memories are determined to be used in the redundant configuration, whether the redundancy configuration of the plurality of memories is to be cancelled;
• and
• cancelling, when the redundancy configuration of the plurality of memories is determined to be cancelled, the redundancy configuration of the plurality of memories in at least one processor operating normally among the plurality of processors.

A computer-readable recording medium having stored therein a program for information processing that causes an information processing apparatus comprising a plurality of processors each comprising a plurality of memories and a memory controller that controls the plurality of memories to function as:

• a normality checker that checks whether the plurality of processors operate normally when the information processing apparatus is started;
• a failure detector that finds any failed processor on the basis of a result of the checking by the normality checker;
• a fallback unit that falls back a failed processor if any;
• a redundancy determiner that determines whether the plurality of memories are used in a redundancy configuration that makes the plurality of memories redundant;
• a redundancy cancellation determiner that determines, when the redundancy determiner determines that the plurality of memories are used in the redundant configuration, whether the redundancy configuration of the plurality of memories is to be cancelled;
• and
• a redundancy canceller that cancels, when the redundancy cancellation determiner determines that the redundancy configuration of the plurality of memories is to be cancelled, the redundancy configuration of the plurality of memories in at least one processor operating normally among the plurality of processors.
