Abstract
A storage apparatus configures a second transfer unit of data based on a zHL read request from a transfer unit of data based on a fiber connect read request, calculates a warranty code for the data of the second transfer unit, stores the data and the warranty code in a memory; after receiving a read request based on zHL, transfers the data together with the warranty code to a host computer if it is determined that the data of the second transfer unit, which is a target of the read request, exists in the memory; and sends a notice of an error of the read request to the host computer when the data of the second transfer unit, which is the target of the read request based on zHL, does not exist in the memory, wherein the host computer which has received the notice outputs a read request.
