Provided is 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 determines which one of the TPGS-compliant multipath driver and the non-TPGS-compliant multipath driver is used in each host, based on whether a command that only the TPGS-compliant multipath driver transmits is received or not and, when receiving a command needing a sense response from the host (50) in which the non-TPGS-compliant multipath driver is used via a path set as the standby path (S301; Yes, S302; Yes, S303; No), ignores the standby path setting and processes the command. [Reference numerals] (AA) Start; (BB,DD,FF) No; (CC,EE,GG) Yes; (HH) End; (S301) Sense responding target command?; (S302) Is a comm. path a standby path?; (S303) Is a sender an RTPG issued initiator?; (S304) Perform command processing; (S305) Reply sense "2/040B" |
