STORAGE CONTROL APPARATUS, METHOD OF SETTING REFERENCE TIME, AND COMPUTER-READABLE STORAGE MEDIUM STORING REFERENCE TIME SETTING PROGRAM

摘要

With a command delay time measurement unit that issues a first test command while the medium error status generator generates the medium error status, and measures a delay time of a command response for the first test command as a command delay time, and a response interval measurement unit that issues a plurality of second test commands to the storage apparatuses to be examined under a higher load when no error occurs, and measures an interval of each command response for the plurality of second test commands as a response interval, and by calculating, for each of the plurality of types of the storage apparatuses, a reference time for each storage apparatus type by adding the command delay time and the response interval, an error can be detected more efficiently.
