Ron, By balanced I mean an even spread across the volumes.
Our DASD farm is built from SAN type storage and cached so I/O performance, right now, is not a major concern. It may be down the road, but not now. In addition, the process using these files has its own caching mechanism in place so all I am looking for is some tool to help me place the files in a somewhat, allocation based, balanced order.

I'm sure you mean something else. Do you mean balanced in terms of space, number of datasets, or do you simply need them spread randomly across "up to" 70 volumes.

While some of you offered some good ideas on how to handle the problem, none of them presented was an automated process, which is what I was hoping for. Some of you asked questions about types of files and cross LPAR conditions and I will not go into those details. Suffice it to say, I have 1500+ files of varying sizes and I need to balance their placement across 70 volumes. If no one knows of a tool out there that can do this, then you have all fulfilled my need. I will have to, I guess, invent the wheel.

Sent: Thursday, October 08, 2015 9:25 PM To: IBM-MAIN@LISTSERV.UA.EDU Subject: File Placement Utility I have a need to juggle the locations of 1500+ files on 70 volumes. These packs are not SMS managed and will never be. There will be 4 sets of these files across 4 sets of 70 DASD volumes. Does anyone know of a utility, REXX, EXCEL, executable program, etc, that would let me feed in the file names and sizes, dasd characteristics, etc, and produce a list of what files should be allocated on what packs? The file sizes vary file to file, but they do not expand or contract once allocated and won't change until the next time the files need to be adjusted, which won't hopefully, change for a while.
