The claims below are in addition to those above.
All refrences to claim(s) which appear below refer to the numbering after this setence.
1. A request processing device comprising:
a request sender that sends a write request or a read request to a storage device;
a response processor that receives a response to a request which the request sender has sent; and
a test request processor that converts a read response which is a response to a read request, into a test write request, and converts a write response which is a response to a write request into a test read request, from among responses that the response processor has received or from among responses that have been input from a device which is provided outside the request processing device.
2. The request processing device according to claim 1, wherein the test request processor is capable of operating in two operation modes, which are a test mode and a normal mode, and
