On-line Divided Diagnosis for High-availability Systems
On-line Divided Diagnosis for High-availability Systems
○真矢 讓（日立）
The decrease in availability in mission critical systems has become a serious problem due to open source software and commoditization of hardware. Serious failures such as system-down occur during fault recover processing even in the high-availability systems. To solve this problem, I propose an on-line divided diagnosis. This scheme divides high-availability functions into several sub-functions and diagnoses each sub-function in on-line processing. It acquires the system status at the diagnosis of the sub-function. I show that availability can be improved because the proposed scheme suppresses fault occurrence during fault recovery processing.
