    Abstract: A storage system with redundant mass storage device arrays determines that a mass storage device is non-responsive, and individually offlines the specific mass storage device for a temporary period. Reads to the offline mass storage device may be temporarily prevented from reaching the mass storage device, and may be serviced by a redundant array. Write to the offline mass storage device may also be temporarily prevented from reaching the mass storage device, and may be serviced with a temporary storage management that tracks and/or stores write transactions. The mass storage device can be synchronized with the write transactions on the basis of the tracking.

    Abstract: A system and method for managing access to assets in a distributed data storage system includes requesting, from a client computer, a semi-preemptible access lock from a server computer. The semi-preemptible lock, if granted, is held by the client computer as long as the server does not demand it back, with the client computer granting open instances under non-preemptible file locks for the asset to which the locks pertain as long as the client computer holds the semi-preemptible lock. When another client computer requests the semi-preemptible lock, the server can demand the lock from the holding client, which relinquishes the lock if no open instances are protected by the lock. Otherwise, the holding client computer first attempts to downgrade its lock to meet the request, and if compatibility is not achieved thereby, the holding client refuses to relinquish the lock.

    Abstract: An improved method for automatically focusing an integrated circuit manufacturing projection step and repeat photolithography printer employing an optical signal to focus the printer is disclosed. The automatic focusing is achieved by reflecting an optical signal off a photoresist layer on the surface of a wafer and converting the reflected optical signal into an electronic signal employed to focus the printer. According to the preferred embodiment of the present invention, a dye which absorbs light at the wavelength the optical signal is added to the photoresist layer to improve the quality of the reflected optical signal thereby considerably reducing or eliminating focusing errors.
