Abstract
An information processing apparatus of the embodiment includes: a data storage unit to store a virtual address in association with first information that includes at least identification information of a slot; and circuitry. And the circuitry is configured to: detect an interrupt that notifies an operating system that a first PCI card was replaced and is output from a second PCI card by which the first PCI card was replaced on a certain slot; extract, from the data storage unit, a virtual address associated with first information that includes identification information of the certain slot, upon detecting the interrupt; and set the second PCI card so as to communicate using the extracted virtual address.
