Abstract
A failure detection method including: detecting, by a virtual computer, occurrence of the failure in a virtual function of an I/O device; acquiring, a virtual device name corresponding to the virtual function in which the failure has occurred; referring, to device information retaining a virtual device name of the I/O device assigned to the virtual computer and VF specific information on the I/O device, thereby acquiring the VF specific information based on the acquired virtual device name; transmitting, the acquired VF specific information to the host; referring, by the host, to I/O correspondence information retaining a slot number of a slot in which the I/O device is mounted, and VF specific information, thereby acquiring the slot number corresponding to the VF specific information received from the virtual computer; and identifying, the acquired slot number as the slot number of the I/O device on which the failure has occurred.
