Abstract

A processing apparatus that constitutes an information processing system includes: a device that constitutes the processing apparatus; and a processing unit that detects an abnormality in the device, that counts the number of the abnormalities detected in the device, and that logically separates the device from the information processing system when the counted number of the abnormalities detected in the device is equal to or greater than a threshold.

Claims

1. A processing apparatus that constitutes an information processing system, the processing apparatus comprising:

a device configured to constitute the processing apparatus; and

a processing unit configured to detect an abnormality in the device, to count a number of the abnormalities detected in the device, and to logically separate the device from the information processing system when the counted number of the abnormalities detected in the device is equal to or greater than a threshold.

2. The processing apparatus according to claim 1, wherein

the processing unit performs reboot of the device when the number of the abnormalities detected in the device is less than the threshold.

3. The processing apparatus according to claim 2, wherein the processing unit

obtains, from another processing apparatus, operation status information related to an operation status of a device of the other processing apparatus,

according to the operation status information, determines whether a redundant state for the device is achieved when the device is logically separated, and

according to a result of the determination, adjusts the threshold for the number of the abnormalities related to the device.

4. The processing apparatus according to claim 3, wherein

when the redundant state for the device is not achieved due to the logical separating of the device, the processing unit sets a threshold that is higher than the threshold that is set when the redundant state for the device is achieved.

5. The processing apparatus according to claim 1, wherein the processing unit

reboots a device located between the devices when an abnormality between the devices is detected, and specifies the rebooted device as a fault portion when an abnormality is not detected within a predetermined time period,

reboots a device located between the devices that is different from the previously rebooted device when an abnormality between the devices is detected again within the predetermined time period, and specifies the rebooted device as a fault portion when an abnormality is not detected within the predetermined time period, and

determines the rebooted device as an abnormality in the device specified as the fault portion.

6. A non-transitory computer-readable record medium having stored therein a program for causing a processing apparatus that constitutes an information processing system to execute a process comprising:

detecting an abnormality in a device that constitutes the processing apparatus;

counting a number of the abnormalities detected in the device; and

logically separating the device from the information processing system when the counted number of the abnormalities detected in the device is equal to or greater than a threshold.

7. The non-transitory computer-readable record medium according to claim 6, wherein

the logically separating performs reboot of the device when the number of the abnormalities detected in the device is less than the threshold.

8. The non-transitory computer-readable record medium according to claim 7, wherein

the logically separating obtains, from another processing apparatus, operation status information related to an operation status of a device of the other processing apparatus, according to the operation status information, determines whether a redundant state for the device is achieved when the device is logically separated, and, according to a result of the determination, and adjusts the threshold for the number of the abnormalities related to the device.

9. The non-transitory computer-readable record medium according to claim 8, wherein

the logically separating sets a threshold that is higher than the threshold that is set when the redundant state for the device is achieved in a case that the redundant state for the device is not achieved due to the logical separating of the device.

10. The non-transitory computer-readable record medium according to claim 6, wherein the logically separating

reboots a device located between the devices when an abnormality between the devices is detected, and specifies the rebooted device as a fault portion when an abnormality is not detected within a predetermined time period,

reboots a device located between the devices that is different from the previously rebooted device when an abnormality between the devices is detected again within the predetermined time period and specifies the rebooted device as a fault portion when an abnormality is not detected within the predetermined time period, and

determines the rebooted device as an abnormality in the device specified as the fault portion.

11. A processing method performed by a processing apparatus that constitutes an information processing system, the processing method comprising:

detecting, by using the processing apparatus, an abnormality in a device that constitutes the processing apparatus,

counting, by using the processing apparatus, a number of the abnormalities detected in the device, and

logically separating, by using the processing apparatus, the device from the information processing system when the counted number of the abnormalities detected in the device is equal to or greater than a threshold.

12. The processing method according to claim 11, wherein

the logically separating performs reboot of the device when the number of the abnormalities detected in the device is less than the threshold.

13. The processing method according to claim 12, wherein

the logically separating obtains, from another processing apparatus, operation status information related to an operation status of a device of the other processing apparatus, according to the operation status information, determines whether a redundant state for the device is achieved when the device is logically separated, and, according to a result of the determination, and adjusts the threshold for the number of the abnormalities related to the device.

14. The processing method according to claim 13, wherein

the logically separating sets a threshold that is higher than the threshold that is set when the redundant state for the device is achieved in a case that redundant state for the device is not achieved due to the logical separating of the device.

15. The processing method according to claim 11, wherein the logically separating

reboots a device located between the devices when an abnormality between the devices is detected, and specifies the rebooted device as a fault portion when an abnormality is not detected within a predetermined time period,

reboots a device located between the devices that is different from the previously rebooted device when an abnormality between the devices is detected again within the predetermined time period, and specifies the rebooted device as a fault portion when an abnormality is not detected within the predetermined time period, and

determines the rebooted device as an abnormality in the device specified as the fault portion.
