Appeal 2007-0426
Application 10/145,307
Appellants invented a method and an apparatus for increased data
storage performance in multiple primary storage devices wherein an unused,
unassigned storage device is selected to be used as a replacement drive when
one of the primary storage devices fails (Specification 6).
Claim 1, which is representative of the claims on appeal, reads as
follows:
1. A method in a data processing system for increasing data storage
performance, the data processing system having a plurality of primary
storage devices and a first unused, unassigned storage device, the method
comprising the computer-implemented steps of:
establishing a logical volume definition that defines a logical volume
utilizing said plurality of primary storage devices;
detecting a failure of a first storage device of said plurality of primary
storage devices; and
in response to said detecting step, reconstructing data stored on said
first storage device from data on other storage devices of said plurality of
primary storage devices to form reconstructed data, saving said
reconstructed data to said first unused, unassigned storage device, and
automatically assigning, within said logical volume definition, said first
unused, unassigned storage device to be a replacement primary device for
said first storage device.
The prior art relied upon by the Examiner in rejecting the claims on
appeal is:
Dunphy, Jr. US 5,077,736 Dec. 31, 1991
Golasky US 6,880,101 B2 Apr. 12, 2005
The Examiner rejected claims 1, 3-9, 11-17, and 19-22 under
35 U.S.C. § 103(a) based upon the teachings of Dunphy and Golasky.
