In a computer system including a storage system which has a plurality of storage areas and a first port that is coupled to a computer with a second port via an IP network, and including an iSNS server coupled to the storage system and the computer via the IP network, the method comprising the steps of:

• assigning one of the plurality of storage areas to the computer;
• sending, to the iSNS server, a command which includes configuration information of the one storage area if the one storage area is assigned,
• storing, by the iSNS server, a relationship between a plurality of portals and a plurality of storage nodes in the IP network based on the configuration information so that the relationship between the plurality of portals and the plurality of storage nodes is synchronized to the configuration of the one storage area.

In a computer system including a storage system which has a plurality of storage areas and a plurality of ports, a computer is coupled to the storage system via an IP network, and an iSNS server coupled to the storage system and the computer via the IP network, a method comprising the steps of:

• assigning, to the computer, a first storage area of the plurality of storage areas via a first port of the plurality of ports and the IP network;
• defining discovery domain (DD) information such that a plurality of portals belonging to a DD can access each other by using a discovery request,
• updating the DD information on the basis of information related to the step of assigning.
