Abstract

There is provided an information processing apparatus that includes a CPU board 1 having a processing unit, a control device (CPU 11, CPU board controller 12, and the like) that is mounted on the CPU board 1 and includes hardware replacement management area 16 that stores replacement information indicating that the CPU board 1 has been replaced, the replacement information initialized at the time when the information processing apparatus is started or when the CPU board 1 is replaced, a memory 13 that stores error information based on occurrence of an error in the control device, the error information initialized at the time when the information processing apparatus is started, an initialization control section 18 that initializes the information processing apparatus, and a unit control section 45 that includes an error monitoring section 42 that monitors the error information stored in the memory 13 and controls the CPU board 1.

Claims

1. An information processing apparatus including a unit having a processing unit, comprising:

a control device that is mounted on the unit and includes a replacement information storage section that stores replacement information indicating that the unit has been replaced, the replacement information initialized at the time when the information processing apparatus is started or when the unit is replaced;

a first storage device that stores error information based on occurrence of an error in the control device, the error information initialized at the time when the information processing apparatus is started;

an initialization control section that initializes the information processing apparatus; and

a unit control section that includes an error monitoring section that monitors error information stored in the storage device, and controls the unit.

2. The information processing apparatus according to claim 1, wherein

the information processing apparatus further includes a system control device that controls the information processing apparatus, and

the unit control section further includes:

an error notification section that notifies the error information to the system control device; and

an error notification disabling section that disables notification of the error information to the system control device by the error notification section when an occurrence frequency of the error exceeds a predetermined frequency.

3. The information processing apparatus according to claim 1, wherein

the error information stored in the first storage device is initialized by the initialization control section when the information processing apparatus is started.

4. The information processing apparatus according to claim 1, wherein

the error information stored in the first storage device is stored by the system control section when an error occurs in the control device.

5. The information processing apparatus according to claim 1, wherein

the information processing apparatus further includes a second storage device that is different from the first storage device, and

the processing device functions as an initialization control section when an initialization firmware stored in the second storage device is executed.

6. The information processing apparatus according to claim 5, wherein

the information processing apparatus further includes a third storage device that is different from the first storage device and the second storage device, and

the processing device functions as the unit control section when a control firmware stored in the third storage device is executed.

7. The information processing apparatus according to claim 6, wherein

the third storage device is mounted on the unit.

8. A medium that records an error notification program that controls a computer to execute error notification when an error occurs in the inside of a unit that can be replaced even during operation of an information processing apparatus in a manner readable by the computer, the error notification program controlling the computer to execute:

initializing replacement information retained in a storage device included in the unit and indicating that the unit has been replaced, when the unit is replaced;

initializing disabled information indicating that notification of an error is disabled and setting a predetermined value to the replacement information, when the replacement information is initialized and an error occurs;

setting a predetermined value to the disabled information based on an error occurrence frequency; and

disabling notification of an error when the predetermined value is set to the disabled information, and notifying an error when the predetermined value is not set to the disabled information.

9. The medium that records the error notification program according to claim 8, further controls a computer to execute determining whether start of the information processing apparatus or start accompanying replacement of a unit takes place, wherein

in the initialization of the replacement information, the disabled information is initialized when a result of the determination indicates start of the information processing apparatus.

10. An error notification method of when an error occurs in the inside of a unit that can be replaced even during operation of an information processing apparatus, the error notification method that executes:

initializing replacement information retained in a storage device included in the unit and indicating that the unit has been replaced, when the unit is replaced;

initializing disabled information indicating that notification of an error is disabled and setting a predetermined value to the replacement information, when the replacement information is initialized and an error occurs;

setting a predetermined value to the disabled information based on an error occurrence frequency; and

disabling notification of an error when the predetermined value is set to the disabled information, and notifying an error when the predetermined value is not set to the disabled information.
