Patent ID: 7290167

Claim:
In a system including a management server, a plurality of processor devices, and a plurality of storage devices, the processor devices and the storage devices being coupled via a network, a method for the management server to establish clustering system comprising: storing mapping information between application programs being executed by the processor devices and portions of storage implemented in the storage devices being utilized by the application programs, and storage device information relating to each of the storage devices; receiving a command, from a user interface, identifying a primary processor device and an application program executed by the primary processor device; specifying at least one portion of storage implemented in at least one primary storage device utilized by the identified application program from the storage devices based on the identified primary processor device, the identified application program and the mapping information, the at least one portion of storage implemented in at least one primary storage device and the primary processor device being configured to be a primary computer resource; specifying at least one portion of storage implemented in at least one secondary storage device to which data stored in the specified at least one portion of storage implemented in at least one primary storage device can be copied based on the storage device information, the at least one portion of storage implemented in the at least one secondary storage device and a secondary processor device corresponding to the specified primary processor being configured to be at least one secondary computer resource, the secondary processor device being configured to be a member of a cluster of which the primary processor device is a member, the at least one portion of storage implemented in the at least one secondary storage device being accessible from the secondary processor device; and presenting, to the user interface, the at least one portion of storage implemented in at least one secondary storage device and the secondary processor device to select a redundant computer resource corresponding to the primary computer resource from the at least one secondary computer resource.
