Storage device, control method for storage device and control program

摘要

A storage device that can be used without problems in an environment where TPGS-compliant and non-TPGS-compliant multipath drivers are used. The storage device judges which one of the TPGS-compliant multipath driver and the non-TPGS-compliant multipath driver is used in each host 50 based on whether a command that only the TPGS-compliant multipath driver transmits is received or not, and, when receiving a command to which a sense is to be returned from the host in which the TPGS-compliant multipath driver is used via a path set as the standby path, processes the command in a way that ignores the standby path setting.
