Abstract:
1. A disk array device having at least one volume from/to which data is read/written based on an access request transmitted from a first client device via a server device and a storage area network (SAN), the disk array device comprising: a failure generation unit for generating a simulated internal failure of said disk array device; an access request transmission unit simulating as a second client device for creating a simulated access request as if issued from the second client device and transmitting the simulated access request from said disk array device to said server device via a local area network (LAN), the simulated access request being a write or read request for accessing data stored in said disk array device via the LAN, the server device and the SAN; and a verification unit for verifying a setting of said server device for a response to said simulated internal failure based on comparison data, stored in the disk array device and corresponding to the simulated access request transmitted from said access request transmission unit simulating as the second client device in a state that said simulated internal failure is being generated by said failure generation unit, with a response of said server device to the simulated access request transmitted from said access request transmission unit simulating as the second client device.
