Information processing apparatus, processing unit switching method and storage medium storing processing unit switching program

A processing unit switching method executed by an information processing apparatus for processing information by executing a system operation, the method comprising:

• diagnosing an active unit that is activated for executing the system operation, and includes a first processing units each having a first storing device and a first processor performing a computation;
• diagnosing a standby unit that stands by for executing the system operation, and includes second processing units each having a second storing device and a second processor performing a computation;
• monitoring the diagnosis of the active unit;
• and embedding the standby unit in the information processing apparatus by switching a first processing unit in which an abnormality is detected to a second processing unit which is not being diagnosed when the abnormality in the first processing unit is detected

A non-transitory computer-readable storage medium storing a processing unit switching program for causing an information processing apparatus execute process for processing information by executing a system operation, the process comprising:

• diagnosing an active unit that is activated for executing the system operation, and includes a first processing units each having a first storing device and a first processor performing a computation for information held in the first storing device connected to the first processor;
• diagnosing a standby unit that stands by for executing the system operation, and includes second processing units each having a second storing device and a second processor performing a computation for information held in the second storing device connected to the second processor;
• monitoring the diagnosis of the active unit;
• and
• embedding the standby unit in the information processing apparatus by switching a first processing unit belonging to the active unit from which an abnormality is detected to a second processing unit belonging to the standby unit which is not being diagnosed based on a diagnosis schedule for the second processing units when the monitoring detects the abnormality in the first processing unit.
