COMPUTER SYSTEM, STORAGE APPARATUS AND CONTROL METHOD

摘要

A computer system has a storage system including a first port and a second port, and a relay apparatus which couples the first port to an initiator apparatus. The storage apparatus stores relay apparatus information indicating a relay apparatus, and initiator information indicating an initiator apparatus. The storage apparatus establishes communications between the first port and a first relay apparatus, and based on communications with the relay apparatus recognizes the initiator apparatus with which the first relay apparatus has established communications. The storage apparatus also stores, in pathway information, a first pathway containing the first port, the first relay apparatus and the initiator apparatus. The storage apparatus creates a virtual port, which is a virtual port to which the first port is allocated, and when an initiator apparatus establishes communications with the virtual port, this apparatus adds a first virtual port associated pathway, in which the virtual port is associated with the first pathway, to the pathway information.

主权项

1. A computer system comprising a storage system including a first port and a second port, and
one or more relay apparatuses which couple the first port to an initiator apparatus, and which couple the second port to the initiator apparatus, wherein the storage system: establishes communications between the first port and the first relay apparatus, creates a virtual port which is a virtual port associated with the first port, and establishes communications between the virtual port and the first relay apparatus, and when the initiator apparatus has established communications with the virtual port and communications between the second port and the first relay apparatus have been established, the storage system: recognizes, based on communications with the first relay apparatus, that communications have been established between the second port and the first relay apparatus and also that communications have been established between the first relay apparatus and the initiator, stores as a first pathway an association between the first port, the first relay apparatus and the initiator apparatus, associates the virtual port with the first port and stores this association, and stores as a second pathway an association between the second port, the first relay apparatus and the initiator apparatus.
