Computer system and computer system management method

摘要

A computer system in which one or more host computers 30 having a FC (Fibre Channel) node port and one or more storage apparatuses 40 having a FC node port are coupled via a FC fabric. The storage apparatus acquires first information related to access control for controlling access to a relevant storage apparatus by the host computer. The storage apparatus, based on the first information, creates second information for defining the host computer that is able to access the relevant storage apparatus, and registers this second information in the fabric.

主权项

1. A computer system comprising:
at least one host computer having a node port; and a plurality of storage apparatuses, each of the storage apparatuses having a node port, the at least one host computer and the plurality of storage apparatuses coupled via a fabric, wherein the plurality of storage apparatuses comprise a first storage apparatus and a second storage apparatus, and wherein, prior to changing an access target from the first storage apparatus to the second storage apparatus for sending an I/O request to a logical volume, the second storage apparatus is configured to: acquire, directly or indirectly from the first storage apparatus, a host group information, which denotes a relationship between at least one port identifier of the at least one host computer and a logical unit identifier of the logical volume inside the first storage apparatus; create, based on the host group information in the first storage apparatus, zone information for defining one of the at least one port identifier of the at least one host computer that is able to access a port identifier of the second storage apparatus; and register the created zone information in the fabric.
