Electronic apparatus, method for controlling electronic apparatus, and non-transitory recording medium

A method for controlling an electronic apparatus including a plurality of processing devices, the method comprising:

• based on reception of an abnormality occurrence notification from at least one of the plurality of processing devices detecting an occurrence of an abnormality, transmitting a restart preparation instruction to a rest of the plurality of processing devices other than a transmission source of the abnormality occurrence notification;
• waiting for a preparation completion notification in response to transmission of the restart preparation instruction, or an extension request of a time-out time, from each of the plurality of processing devices, the preparation completion notification indicating completion of preparation for restart, the extension request being transmitted based on a determination that the preparation completion notification is not to be transmitted within the time-out time;
• powering off and restarting each of the plurality of processing devices in response to one of:
• a) reception of the preparation completion notification from all of the plurality of processing devices before an elapse of the time-out time, and b) the elapse of the time-out time;
• and
• extending the time-out time by an extension time in response to reception of the extension request, and powering off and restarting each of the plurality of processing devices in response to one of:
• c) reception of the preparation completion notification from all of the processing devices before an elapse of the extension time, and d) the elapse of the extension time.

A non-transitory recording medium storing a plurality of program codes which, when executed by one or more processors, causes the processors to perform a method for controlling power supply to each of a plurality of processing devices of an electronic apparatus, the method comprising:

• based on reception of an abnormality occurrence notification from at least one of the plurality of processing devices detecting an occurrence of an abnormality, transmitting a restart preparation instruction to a rest of the plurality of processing devices other than a transmission source of the abnormality occurrence notification;
• waiting for a preparation completion notification in response to transmission of the restart preparation instruction, or an extension request of a time-out time, from each of the plurality of processing devices, the preparation completion notification indicating completion of preparation for restart, the extension request being transmitted based on a determination that the preparation completion notification is not to be transmitted within the time-out time;
• powering off and restarting each of the plurality of processing devices in response to one of:
• a) reception of the preparation completion notification from all of the plurality of processing devices before an elapse of the time-out time, and b) the elapse of the time-out time;
• and
• extending the time-out time by an extension time in response to reception of the extension request, and powering off and restarting each of the plurality of processing devices in response to one of:
• c) reception of the preparation completion notification from all of the processing devices before an elapse of the extension time, and d) the elapse of the extension time.
