Abstract:
1. An information system comprising: an IP network; host computers coupled to the IP network by first IP addresses; a storage apparatus coupled to the IP network by a second IP address and providing a logical volume using an iSCSI target name; an iSNS server coupled to the IP network; and a management computer coupled to the IP network, wherein the iSNS server stores iSCSI name information including associations between the first IP addresses and iSCSI initiator names and an association between the second IP address and an iSCSI target name, sends the iSCSI initiators names to the host computers, and sends the iSCSI target name to the storage apparatus, wherein the storage apparatus stores access information including an accessible iSCSI initiator name for the iSCSI target name, and wherein the management server is configured to: (A) acquire the accessible iSCSI initiator name from the storage apparatus; (B) acquire a corresponding IP address which is corresponding to the accessible iSCSI initiator name, from the iSNS server; (C) store the corresponding IP address as a discovery target into discovery target information; and (D) send a discovery request to a first part of the host computers via the IP network using the corresponding IP address.
