  • Method and apparatus for reducing space allocation failures in storage management systems
    Patent number: 6591334
    Abstract: A method and apparatus for reducing space allocation failures in a computer system that utilizes direct access storage devices to store data. The method comprises the steps of determining if authorization has been given to attempt to allocate an initial space request over more than one volume, and, if so, attempting to allocate space on a plurality of volumes. If the initial space request cannot be allocated on a plurality of volumes, the initial space request is reduced by a preset percentage, the five-extent limit is removed and an attempt is made to allocate the reduced space request on the plurality of volumes with the five extent limit removed. Alternatively, if authorization has not been given to attempt to allocate the initial space request over more than one volume, the initial space request is reduced by a preset percentage, the five-extent limit is removed and an attempt is made to allocate the reduced space request on a single volume.
