Management method and a management system for volume

A computer system comprising:

• a storage system having a plurality of storage areas and a plurality of ports;
• and
• an iSNS server, coupled to the storage system via an IP network, which manages relationship between a plurality of portals and a plurality of storage nodes in the IP network,
• wherein the storage system sends a command which includes configuration information of the plurality storage areas to the iSNS server if a configuration of the plurality of storage areas is changed,
• wherein the iSNS server modifies the relationship between the plurality of portals and the plurality of storage nodes based on the configuration information sent by the storage system when the iSNS server receives the command from the storage system via the IP network so that the relationship between the plurality of portals and the plurality of storage nodes should be synchronized to the configuration of the plurality of storage areas.

A computer system comprising:

• a storage system which has a plurality of storage areas and a plurality of ports, is coupled to a plurality of computers via an IP network, and stores restriction information whether a first computer of the plurality of computers can access to a first storage area of the plurality of storage areas via a first port of the plurality of ports and the IP network or not;
• an iSNS server, coupled to the storage system and the plurality of computers via the IP network, which stores discovery domain (DD) information that a plurality of portals belonging to a DD can access each other by using a discovery request and the iSNS server;
• and
• a management computer, coupled to the storage system, which indicates the iSNS server to modify the DD information if the restriction information is changed.

A storage system, coupled to an iSNS server which manages relationship between a plurality of portals and a plurality of storage nodes in an IP network via the IP network, comprising:

• a plurality of ports coupled to the IP network;
• a control unit coupled to the plurality of ports;
• and
• a plurality of storage areas coupled to the control unit,
• wherein the control unit sends a command which includes configuration information of the plurality storage areas if a configuration of the plurality of storage areas is changed so that the iSNS server modifies the relationship between the plurality of portals and the plurality of storage nodes based on the configuration information sent by the storage system.
