Patent ID: 7890645

Claim:
An information processing system comprising: a storage apparatuses having volumes that are memory areas; a host apparatuses which use said volumes of said storage apparatuses via iSCSI protocol; and a management server managing said storage apparatuses and said host apparatuses as apparatuses, wherein said management server refers to discovery target address management information and describing IP addresses of discovery targets, and issues a transmission instruction of constitution information on said apparatuses, with respect to said IP addresses of said discovery targets, and, wherein, if a response of said transmission instruction is given, said management server memories said IP address of an apparatus which has returned said response, as a monitoring target apparatus, into discovered apparatus management information; wherein said management server acquires said constitution information on said monitoring target apparatus, and wherein said management server memories said constitution information into device-coupling management information in such a manner that iSCSI target names coupled to said volumes, iSCSI initiator names permitted to access said volumes, and coupling-destination host IDs corresponding to said iSCSI target names are made related with each other; and wherein, if an iSNS server has been registered into said discovered apparatus management information, said management server refer to said device-coupling management information, detects a volume for which said coupling-destination host corresponding to said iSCSI target name is unknown, acquires an access-permitted iSCSI initiator name corresponding to said volume for which said coupling-destination host is unknown, requests said registered iSNS server to acquire said IP address corresponding thereto, and memories said acquired IP address into said discovery target address management information and said discovered apparatus-management information.
