Abstract
Provided are a computer program product, system, and method for providing a reserved data area to use to extend a data set. A data set is configured in the volume configured in the storage. A reserved data area is configured in the storage for the volume. The reserved data area is used to extend the data set in the volume in response to there being insufficient available space in the data set. The reserved data area is used to allocate for use in the volume in response to there being no more available free space for use in the volume and if the reserved data area is available.
Claims20
A computer program product for managing space assigned to data sets configured in a volume in a storage, wherein the computer program product comprises a computer readable storage medium having program instructions embodied therewith, the program instructions executable by a processor to cause operations, the operations comprising:
- configuring a data set in the volume configured in the storage;
- configuring a reserved data area in the storage for the volume, wherein the reserved data area includes physical space in the storage contiguous with respect to the physical space of the data set, wherein one physical address of the data set is contiguous with respect to one physical address of the reserved data area;
- using the reserved data area to extend the data set in the volume in response to there being insufficient available space in the data set;
- and
- using the reserved data area to allocate for use in the volume in response to there being no more available free space for use in the volume and if the reserved data area is available.
A system for managing space assigned to data sets configured in a volume in a storage, comprising:
- a processor;
- and
- a computer readable storage medium having program code executed by the processor to perform operations, the operations comprising:
- configuring a data set in the volume configured in the storage;
- configuring a reserved data area in the storage for the volume, wherein the reserved data area includes physical space in the storage contiguous with respect to the physical space in the data set, wherein one physical address of the data set is contiguous with respect to one physical address of the reserved data area;
- using the reserved data area to extend the data set in the volume in response to there being insufficient available space in the data set;
- and
- using the reserved data area to allocate for use in the volume in response to there being no more available free space for use in the volume and if the reserved data area is available.
A method, comprising:
- configuring a data set in a volume configured in a storage;
- configuring a reserved data area in the storage for the volume, wherein the reserved data area includes physical space in the storage contiguous with respect to the physical space in the data set, wherein one physical address of the data set is contiguous with respect to one physical address of the reserved data area;
- using the reserved data area to extend the data set in the volume in response to there being insufficient available space in the data set;
- and
- using the reserved data area to allocate for use in the volume in response to there being no more available free space for use in the volume and if the reserved data area is available.
