Abstract:
A logical central processing unit (logical CPU) selects a target device. When the target device is shared by another logical CPU, the logical CPU determines whether the logical CPU is in charge of exclusively making diagnosis of the target device. When the target device is not shared by another logical central processing unit or when the logical CPU is exclusively in charge of making diagnosis of the target device, the logical CPU makes diagnosis of the target device and stores a result of diagnosis in a storage unit.
