|Fast, Efficient and Minimally Disruptive z/OS DASD Volume Reorganization
Modern disk arrays are still regarded by the z/OS operating system as a set of conventional DASD Volumes. Each logical volume in the array has a fixed number of cylinders, and space is managed in the usual way – with a standard VTOC and VTOCIX.
As described in more detail in the Case for FASTCPK White Paper or in the Technical section, the issues of fragmented freespace, multi-extent datasets, over-allocated datasets and wasted space are as important today as they have always been.
FASTCPK is a DASD Volume reorganization tool that provides a fast, efficient and minimally disruptive solution to a wide range of DASD related Storage Management issues, including:
Simulation & Reporting
FASTCPK can produce a wide range of information, in both detailed and summary format.
Before and After maps can be produced for each volume processed, either on a SIMULATE or a real Compaktion, together with a concise summary of the effects of the Compaktion.
Here is an example of the summary report:
