VANTAGE Space Total for Multivolume Datasets

Issue/Introduction

If the multivolume dataset is residing on 10 volumes with 2 GB on each volume, that makes a total of 20 GB for the entire dataset.
 
If looking for datasets that are bigger than, for example, 15 GB and setting a filter with ('Allocated Bytes' > 15000000000), the dataset is not found because every portion of the multi-volume file is only 2 GB.

Is there a simple solution for this request? In the tree under "Data Set Management" I checked both "All Data Sets" and "Multi Volume Data Sets", but couldn't find a column with the dataset total, only the amount per volume.

Environment

Vantage 

Resolution

The solution could be achieved using a JOIN object in Vantage.

This object will combine Details and Summaries objects information into one new Join Object. Follow the wizard to create a join object, where "Details object" is the Base object and the Candidate object is a "summary of multivol data sets". In the Relationship between Base and Candidate object select Data Set Name.

This creates a combined object that includes information from both objects, where the key is the dataset name. 

In the view of the output definition, enable just the following column to display:

Dataset name, Volume, EAV, Allocated Total over All volumes (from summaries), Allocated on Volume (from details), Data class name.

If the dataset resizes to over 3 volumes, the object will have 3 lines: 

DNS Name, Volser, EAV, Total size 3 Vols, Size on this concrete volser, Data Class Name

This object allows to filter based on  'Total size over 3 Vols' > threshold AND 'EAV' =N AND 'DC-name' EXCL(DATA CLASS).
