To reduce current storage shortages, you need to analyze the data returned by IBM's DCOLLECT utility to work out which datasets are over allocated, unreferenced or wasting the most space.
There are commercial products that can perform this function for you (including MXI with its "Storage Management" plugin) - and I imagine that there could also be DCOLLECT post-processing REXX execs in the public domain (check www.cbttape.org). Long term strategy for reducing storage usage will probably involve changes to the HSM policy and the SMS ACS routines and regular examination of the DCOLLECT records will help ensure your DASD farm is being effectively used.

Can someone suggest the best practices i could follow to achieve this.
