Patent ID: 8397102

Claim:
A non-transitory computer readable medium storing a computer program for a management server for managing failure information in a system, wherein the system includes at least one storage device equipped with a real volume, a virtualization device coupled to said at least one storage device and providing a virtual volume using said real volume of said at least one storage device, the computer program causing the management server to: manage a virtual mapping relation including said virtual volume and a first port of said virtualization device on an access path from a computer to said virtual volume, and a real mapping relation including said real volume provided as said virtual volume and a second port of said storage device on a connection path from a computer to said real volume, and an association between said virtual mapping relation and said real mapping relation; receive a plurality of failure notifications from said at least one storage device and said virtualization device at which a failure is detected; detect a first failure notification, which notifies a failure of at least one element in said virtual mapping relation, from said plurality of failure notifications, and a second failure notification, which notifies a failure of at least one element in said real mapping relation, from said plurality of failure notifications; associate said first failure notification with said second failure notification based on said association between said virtual mapping relation and said real mapping relation; and output results of said associating step, in which said first failure notification and second failure notification are associated with a particular cause.
