Patent ID: 8010836

Claim:
A storage configuration recovery method of recovering a storage configuration of a non-duplicated virtualization apparatus upon failure, in which post-recovery operation is performed without passing through the non-duplicated virtualization apparatus when failure occurs in the non-duplicated virtualization apparatus in a storage management system in which a plurality of hosts, a plurality of storages including a plurality of volumes and the non-duplicated virtualization apparatus for causing the plurality of storages to be identified with one storage can make communication through a first network and the host, the storages and the non-duplicated virtualization apparatus can make communication with a management server through a second network, wherein the management server comprising: a configuration information getting step to get configuration information of the non-duplicated virtualization apparatus and configuration information of the storages; a failure occurrence detection step to detect failure occurrence in the non-duplicated virtualization apparatus; a volume recovery method decision step to judge whether a physical volume and a pair can be recovered or not when the failure occurrence is detected, and to decide candidates of volume recovery methods; a data recovery method decision step to judge whether data can be recovered or not with the candidates of the volume recovery methods decided in the volume recovery method decision step, and to decide candidates of data recovery methods; and a recovery execution step to execute, when any combination of the candidates of the volume recovery methods and the candidates of the data recovery methods is selected, the selected combined recovery method, and to make a request for constructing a path between the storage relevant to the combined recovery method and the host to the storage.
